Pull request overview
Fixes Android 10+ SecurityException when sharing files via Share.RequestAsync by ensuring URI permission grants are correctly propagated through the share chooser (via ClipData + GrantReadUriPermission), and adds device tests to validate the new intent construction behavior.
Changes:
- Extracted Android file-share intent construction into
ShareImplementation.CreateShareFileIntent(...)and updated the chooser launch to includeGrantReadUriPermission. - Added
ClipDatapopulation for single and multiple file share intents on Android API 29+. - Added Android device tests validating
ClipDatais present for single/multiple file share intents.

Summary
PR #34417 fixes a SecurityException that occurs on Android 10+ when using Share.RequestAsync to share files via a FileProvider URI. The fix correctly adds ClipData to the share intent (both single-file and multi-file cases) and adds ActivityFlags.GrantReadUriPermission to the chooser intent flags. The implementation was validated by two independent try-fix attempts using different approaches, both of which confirmed that ClipData is the correct and idiomatic solution for this class of Android permission issue.
Root Cause
Android 10+ (API 29+) tightened URI permission enforcement. When an app calls startActivity() with an intent containing EXTRA_STREAM (a FileProvider content URI), the system needs to grant read permission to any app that receives the intent. This permission propagation requires ClipData to be set on the intent — without it, the system's share chooser (uid=1000) cannot read the FileProvider URI and logs:
SecurityException: Permission Denial: reading fileProvider uri content://...
requires the provider be exported, or grantUriPermission()
Two issues in the original code:
ClipDatawas not set on the file share intentActivityFlags.GrantReadUriPermissionwas missing from the chooser intent flags
Fix Quality
Assessment: ✅ Good
| Aspect | Evaluation |
|---|---|
| Correctness | ✅ ClipData.NewRawUri (single) + manual ClipData (multi) are idiomatic Android patterns |
| API guard | ✅ IsAndroidVersionAtLeast(29) guard is appropriate and matches test expectations for older devices |
| Testability | ✅ CreateShareFileIntent extracted as internal static enables device testing without launching Activity |
| Test coverage | ✅ Two device tests verify ClipData is set for single-file and multi-file cases, with correct API-level branching |
| Code style | ✅ Clean extraction, well-commented |
Minor observations (not blockers):
PlatformRequestAsync(ShareTextRequest)still lacksGrantReadUriPermissionon the chooser, but text shares don't use FileProvider URIs so this is not a bug.- The
contentTypevariable can benullifFilesis empty, passed tonew ClipData(label, new[] { null }, ...). In practice, empty files would fail validation before reaching this code, andClipDataaccepts null mimeType gracefully. - Attempt 2 from try-fix showed that removing the
IsAndroidVersionAtLeast(29)guard also works on API 29+ devices, but would break the PR's own test on API < 29 (Assert.Null(intent.ClipData)branch). The PR's guard is correct.

Phase 1: Title & Description Review
✅ Title: Good — Minor Refinement Optional
Current: [Android] Fix Share.RequestAsync SecurityException on Android 10+ caused by missing ClipData
Assessment: The title is accurate and informative. It includes the [Android] platform prefix and describes the exact fix. It is on the longer side; a slightly shorter alternative is provided below, but the current title is acceptable.
Optional alternative:
[Android] Share: Fix SecurityException on Android 10+ by adding ClipData to file intents
✅ Description: Good — Keep As-Is
Quality Assessment:
| Indicator | Status | Notes |
|---|---|---|
| NOTE block | ✅ Present | Properly prepended at top |
| Root cause | ✅ Present | Clearly explains missing ClipData and missing GrantReadUriPermission flag |
| Description of change | ✅ Present | Covers implementation, tests, and maintenance items |
| Issues Fixed | ✅ Present | Fixes #34370 |
| Tested platforms | ✅ Present | Android checked, others unchecked |
| Before/After evidence | ✅ Present | Videos attached |
Verdict: The existing description is thorough and accurate. It covers root cause, what changed, why, and testing evidence. Keep as-is.
Phase 2: Code Review Findings
🟡 Suggestions
1. Duplicate comment block could be extracted
- Files:
Share.android.cslines ~93 and ~107 - Issue: The same three-line comment explaining why
ClipDatais needed appears verbatim twice — once for the single-file case and once for the multiple-files case. - Recommendation: Minor nit. Acceptable as-is given the comment clearly explains intent in both branches. Alternatively, extract a helper like
AddClipDataIfNeeded(intent, contentType, contentUris).
2. ClipData gated to Android 10+ (API 29) only
- File:
Share.android.cs - Issue:
ClipDatais only set whenOperatingSystem.IsAndroidVersionAtLeast(29). Android documentation states that whenFLAG_GRANT_READ_URI_PERMISSIONis used,ClipDatashould also be set on the intent for all API levels ≥ 16 (whereClipDatawas introduced), not just API 29+. However, since the reported issue only manifests on Android 10+, limiting the change to API 29+ is a conservative, targeted fix that avoids unintended side-effects on older versions. - Recommendation: Low risk. Acceptable given the bug is scoped to Android 10+. Could be widened to API ≥ 16 for correctness, but that is a separate, lower-priority change.
3. Cast from IParcelable to AndroidUri
- File:
Share.android.cs, e.g.,(AndroidUri)contentUris[0] - Issue:
contentUrisis typedList<IParcelable>, and items in it areAndroid.Net.Urivalues. The direct cast is safe since the items are alwaysAndroid.Net.Uri, but it is an unguarded cast. - Recommendation: Very low risk — the items are always
Android.Net.Uriat this code path. ConsidercontentUris[0] as AndroidUriwith a null check for defensive coding, but not a blocking concern.
✅ Looks Good
CreateShareFileIntentextraction: Correctly extracted to aninternal staticmethod, making it testable without launching an Activity. Solid design decision.GrantReadUriPermissionon chooser intent: Added correctly to thechooserIntent.SetFlags(...)call — this was the missing flag identified in the root cause analysis.ClipDatafor multiple files: Correctly iterates through all URIs and adds each as aClipData.Item. HandlescontentUris.Count > 1vs== 1separately with the appropriateClipData.NewRawUriAPI for single files.- Tests: Both
Share_SingleFileIntent_HasClipDataandShare_MultipleFilesIntent_HasClipDataare correctly gated with#if ANDROID, cover API 29+ branching logic, and clean up temp files infinallyblocks. - Imports:
using System;andusing AndroidUri = Android.Net.Uri;added cleanly without disruption. OperatingSystem.IsAndroidVersionAtLeast(29): Correct API 29 check for Android 10 (Q).
Summary
| Area | Status |
|---|---|
| Title | ✅ Acceptable (minor optional refinement) |
| Description | ✅ Good — keep as-is |
| NOTE block | ✅ Present |
| Code correctness | ✅ Fix is sound |
| Test coverage | ✅ Both single and multi-file scenarios covered |
| Critical issues | None |
| Blocking concerns | None |
Overall verdict: ✅ Ready for merge. The fix is well-targeted, description is accurate, and test coverage validates the intent structure on Android 10+. The two suggestions are minor nits that do not block merge.

Platforms Affected: Android 10+ (API 29+)
Files Changed: 1 implementation, 1 test
Test Type: Device Tests (src/Essentials/test/DeviceTests/Tests/Share_Tests.cs)
Key Findings
- The linked issue reproduces on Android 10+ when sharing a FileProvider-backed file via
Share.RequestAsync; the chooser process (uid=1000) cannot read the URI without the expected permission propagation. - The PR changes only
src/Essentials/src/Share/Share.android.csand adds Android-only coverage insrc/Essentials/test/DeviceTests/Tests/Share_Tests.cs. - The implementation fix has two parts: add
ClipDatato the underlying share intent for single and multi-file requests, and addGrantReadUriPermissionto the chooser flags. - The intent-building logic is extracted into
CreateShareFileIntentfor testability without launching an activity. - Review discussion shows an earlier concern about tests assuming
ClipDataon all API levels; that was addressed by conditioning assertions onOperatingSystem.IsAndroidVersionAtLeast(29). - A prior agent review already concluded the PR was likely correct and selected the PR fix, but this run will independently verify the gate and run mandatory try-fix exploration.
Edge Cases From Discussion
- API levels below 29 should continue to produce
nullClipDatain the new tests. - Multiple-file sharing must add every URI into
ClipData, not just the first item.

Summary
PR #34417 addresses the Android 10+ file-sharing SecurityException by adding ClipData to the inner share intent, preserving URI-read grants through the chooser, and adding coverage around the extracted intent-construction path. I independently explored four alternative fixes and then ran the current PR through pwsh .github/skills/run-device-tests/scripts/Run-DeviceTests.ps1 -Project Essentials -Platform android; that run completed successfully with XHarness exit code: 0 and Tests completed successfully.
Root Cause
The shared FileProvider URI was not being propagated with the metadata Android expects when handing the request through the system chooser. On Android 10+, that means the chooser/receiving app can hit SecurityException when trying to read the file URI. The relevant moving parts are the share intent's ClipData and the read-permission flag used during chooser dispatch.
Fix Quality
The PR's fix is the best candidate reviewed.
- It keeps
ClipDataon the actual data-carrying share intent, which is the cleanest ownership model. - It stays scoped to the reported Android 10+ problem instead of broadening behavior on older releases without a demonstrated need.
- It keeps
GrantReadUriPermissionon the chooser path, which is safer than assuming the chooser flag is redundant. - It extracts
CreateShareFileIntent, which makes the behavior testable without launching an activity.
Comparison With Alternatives
- Attempt 1 passed, but attaching
ClipDatato the chooser wrapper is a less direct representation of the shared payload. - Attempt 2 passed, but removing the API 29 guard changes behavior beyond the reported bug scope and required changing the test contract.
- Attempt 3 passed, but explicit per-package
GrantUriPermissionis more complex and less maintainable than the PR'sClipDatasolution. - Attempt 4 passed, but it omits chooser
GrantReadUriPermission, so it is slightly riskier than the PR even though the device tests still passed.
Recommendation
Approve as-is. I did not find a cleaner or safer alternative than the PR's current implementation.

Phase 2: Code Review Findings
🟡 Suggestions
1. Duplicate comment block could be extracted
- Files:
Share.android.cslines ~93 and ~107 - Issue: The same three-line comment explaining why
ClipDatais needed appears verbatim twice — once for the single-file case and once for the multiple-files case. - Recommendation: Minor nit. Acceptable as-is given the comment clearly explains intent in both branches. Alternatively, extract a helper like
AddClipDataIfNeeded(intent, contentType, contentUris).
2. ClipData gated to Android 10+ (API 29) only
- File:
Share.android.cs - Issue:
ClipDatais only set whenOperatingSystem.IsAndroidVersionAtLeast(29). Android documentation states that whenFLAG_GRANT_READ_URI_PERMISSIONis used,ClipDatashould also be set on the intent for all API levels ≥ 16 (whereClipDatawas introduced), not just API 29+. However, since the reported issue only manifests on Android 10+, limiting the change to API 29+ is a conservative, targeted fix that avoids unintended side-effects on older versions. - Recommendation: Low risk. Acceptable given the bug is scoped to Android 10+. Could be widened to API ≥ 16 for correctness, but that is a separate, lower-priority change.
3. Cast from IParcelable to AndroidUri
- File:
Share.android.cs, e.g.,(AndroidUri)contentUris[0] - Issue:
contentUrisis typedList<IParcelable>, and items in it areAndroid.Net.Urivalues. The direct cast is safe since the items are alwaysAndroid.Net.Uri, but it is an unguarded cast. - Recommendation: Very low risk — the items are always
Android.Net.Uriat this code path. ConsidercontentUris[0] as AndroidUriwith a null check for defensive coding, but not a blocking concern.
✅ Looks Good

Platforms Affected: Android 10+ (API 29+)
Files Changed: 1 implementation, 1 test
Key Findings
- The linked issue reproduces on Android 10+ when sharing a locally generated file; the share action succeeds but preview access triggers a SecurityException because the chooser/receiver lacks URI read permission propagation.
- The PR fixes Android sharing by adding ClipData for single and multiple file share intents on API 29+ and by including GrantReadUriPermission on the chooser intent.
- The PR adds Android device tests in
src/Essentials/test/DeviceTests/Tests/Share_Tests.csthat validate ClipData is present on API 29+ and absent on older Android versions. - Prior review feedback flagged that the tests originally assumed ClipData would always exist; the author updated the tests to gate expectations by Android API level.
- No issue comments introduced additional edge cases beyond Android 10+ behavior; the main environment scope remains Android only.

Summary
PR #34417 fixes a SecurityException that occurs on Android 10+ when using Share.RequestAsync to share files via a FileProvider URI. The fix correctly adds ClipData to the share intent (both single-file and multi-file cases) and adds ActivityFlags.GrantReadUriPermission to the chooser intent flags. The implementation was validated by two independent try-fix attempts using different approaches, both of which confirmed that ClipData is the correct and idiomatic solution for this class of Android permission issue.
Root Cause
Android 10+ (API 29+) tightened URI permission enforcement. When an app calls startActivity() with an intent containing EXTRA_STREAM (a FileProvider content URI), the system needs to grant read permission to any app that receives the intent. This permission propagation requires ClipData to be set on the intent — without it, the system's share chooser (uid=1000) cannot read the FileProvider URI and logs:
SecurityException: Permission Denial: reading fileProvider uri content://...
requires the provider be exported, or grantUriPermission()
Two issues in the original code:
ClipDatawas not set on the file share intentActivityFlags.GrantReadUriPermissionwas missing from the chooser intent flags
Fix Quality
Assessment: ✅ Good
| Aspect | Evaluation |
|---|---|
| Correctness | ✅ ClipData.NewRawUri (single) + manual ClipData (multi) are idiomatic Android patterns |
| API guard | ✅ IsAndroidVersionAtLeast(29) guard is appropriate and matches test expectations for older devices |
| Testability | ✅ CreateShareFileIntent extracted as internal static enables device testing without launching Activity |
| Test coverage | ✅ Two device tests verify ClipData is set for single-file and multi-file cases, with correct API-level branching |
| Code style | ✅ Clean extraction, well-commented |
Minor observations (not blockers):
PlatformRequestAsync(ShareTextRequest)still lacksGrantReadUriPermissionon the chooser, but text shares don't use FileProvider URIs so this is not a bug.- The
contentTypevariable can benullifFilesis empty, passed tonew ClipData(label, new[] { null }, ...). In practice, empty files would fail validation before reaching this code, andClipDataaccepts null mimeType gracefully. - Attempt 2 from try-fix showed that removing the
IsAndroidVersionAtLeast(29)guard also works on API 29+ devices, but would break the PR's own test on API < 29 (Assert.Null(intent.ClipData)branch). The PR's guard is correct.

Key Findings
- The linked issue reports Android 10+
SecurityExceptionwhen the share chooser tries to read aFileProviderURI fromShare.RequestAsync. - The PR changes only Android Essentials sharing code and adds Android-only device tests under
Essentials.DeviceTests. - The PR description and resolved inline review threads indicate the intended behavior is API-sensitive:
ClipDatashould be asserted on API 29+ and expected to be null on older Android versions. - The PR discussion already contains a prior AI summary for this PR; this run continues independently using the same source material.
Edge Cases Noted
- Single-file and multi-file sharing both need coverage.
- Android API < 29 behavior must remain compatible with the test expectations.
- The user-visible symptom in the issue is missing preview/error noise in the chooser, not a total share failure.

Summary
PR #34417 appears to have the right production direction for the Android 10+ sharing bug: adding ClipData and propagating GrantReadUriPermission through the chooser matches the issue report and every successful try-fix variant kept that core idea. However, the PR as submitted is not ready because its new tests are coupled to a helper method that disappears when the broken baseline is restored, so gate verification fails at compile time instead of proving FAIL-without-fix / PASS-with-fix behavior.
Root Cause
There are two layers here. The product bug is the missing URI-permission propagation for shared FileProvider content on Android 10+, which the PR addresses. The review blocker is test design: Share_Tests.cs directly references ShareImplementation.CreateShareFileIntent(...), so when the verification workflow restores the pre-fix baseline, the helper no longer exists and the device tests fail with CS0117 during compilation. That prevents the repository’s gate from validating the fix end-to-end.
Fix Quality
The production fix itself looks strong, but the test strategy needs revision. Try-fix found four passing alternatives, and the best one was Candidate #1: keep the production fix but make the tests invoke the helper via reflection so they always compile and fail at runtime when the helper is absent. That option is better than the submitted PR because it preserves the intended production fix while making the tests compatible with gate verification, without adding extra production-only indirection or hooks.

Key Findings
- The linked issue reports Android 10+
SecurityExceptionwhen sharingFileProviderURIs throughShare.RequestAsync; the provided workaround explicitly setsClipDatain native Android code. - The PR changes
src/Essentials/src/Share/Share.android.csand adds Android-only device coverage insrc/Essentials/test/DeviceTests/Tests/Share_Tests.csfor single-file and multi-file intent construction. - The implementation extracts
CreateShareFileIntent(...)for testability, adds chooserGrantReadUriPermission, and setsClipDataon API 29+ file-share intents. - Prior review discussion flagged missing API guards in the new tests; those review threads are resolved and the tests now assert
ClipDataonly on Android 10+ andnullpre-29. - PR discussion also shows a prior agent review comment. I imported only the factual context (issue, file classification, resolved inline concern) and am re-running Gate/Try-Fix independently.
Edge Cases
- Single-file and multi-file share requests both need URI grant propagation.
- Pre-29 Android is intentionally treated differently by the tests (
ClipDataexpected to remainnull). - Text sharing is unaffected because it does not flow
FileProvidercontent URIs through the chooser.

Summary
PR #34417 fixes a SecurityException that occurs on Android 10+ when using Share.RequestAsync to share files via a FileProvider URI. The fix correctly adds ClipData to the share intent (both single-file and multi-file cases) and adds ActivityFlags.GrantReadUriPermission to the chooser intent flags. The implementation was validated by two independent try-fix attempts using different approaches, both of which confirmed that ClipData is the correct and idiomatic solution for this class of Android permission issue.
Root Cause
Android 10+ (API 29+) tightened URI permission enforcement. When an app calls startActivity() with an intent containing EXTRA_STREAM (a FileProvider content URI), the system needs to grant read permission to any app that receives the intent. This permission propagation requires ClipData to be set on the intent — without it, the system's share chooser (uid=1000) cannot read the FileProvider URI and logs:
SecurityException: Permission Denial: reading fileProvider uri content://...
requires the provider be exported, or grantUriPermission()
Two issues in the original code:
ClipDatawas not set on the file share intentActivityFlags.GrantReadUriPermissionwas missing from the chooser intent flags
Fix Quality
Assessment: ✅ Good
| Aspect | Evaluation |
|---|---|
| Correctness | ✅ ClipData.NewRawUri (single) + manual ClipData (multi) are idiomatic Android patterns |
| API guard | ✅ IsAndroidVersionAtLeast(29) guard is appropriate and matches test expectations for older devices |
| Testability | ✅ CreateShareFileIntent extracted as internal static enables device testing without launching Activity |
| Test coverage | ✅ Two device tests verify ClipData is set for single-file and multi-file cases, with correct API-level branching |
| Code style | ✅ Clean extraction, well-commented |
Minor observations (not blockers):
PlatformRequestAsync(ShareTextRequest)still lacksGrantReadUriPermissionon the chooser, but text shares don't use FileProvider URIs so this is not a bug.- The
contentTypevariable can benullifFilesis empty, passed tonew ClipData(label, new[] { null }, ...). In practice, empty files would fail validation before reaching this code, andClipDataaccepts null mimeType gracefully. - Attempt 2 from try-fix showed that removing the
IsAndroidVersionAtLeast(29)guard also works on API 29+ devices, but would break the PR's own test on API < 29 (Assert.Null(intent.ClipData)branch). The PR's guard is correct.

Issue: #34370 - [Bug] Share.RequestAsync throws java.lang.SecurityException (uid=1000) on Android 10+ due to missing intent.ClipData
PR: #34417 - [Android] Fix Share.RequestAsync SecurityException on Android 10+ caused by missing ClipData
Author: HarishwaranVijayakumar (community ✨, partner/syncfusion)
Platforms Affected: Android (Android 10+ / API 29+)
Files Changed: 1 implementation (Share.android.cs), 1 device test (Share_Tests.cs)
Test Type: Device Tests (Essentials.DeviceTests)
Key Findings
- Root cause confirmed: Android 10+ requires
ClipDataon share intents for URI permission grants via FileProvider. Without it, the system's share chooser (uid=1000) logsSecurityExceptionwhen reading the FileProvider URI. - Two-part fix:
- Added
ClipDatato the file share intent (single-file viaClipData.NewRawUri, multi-file via manual construction), guarded byOperatingSystem.IsAndroidVersionAtLeast(29) - Added
ActivityFlags.GrantReadUriPermissionto the chooser intent flags (was missing before)
- Added
- Refactor for testability: Logic extracted to
internal static CreateShareFileIntent(ShareMultipleFilesRequest)to enable unit/device testing without launching an Activity. - Copilot inline review concerns addressed: API level guard concerns (ClipData assertions on API <29) were raised and subsequently addressed by the author.
- Test coverage: Two new Device Tests added with proper API-level branching:
Share_SingleFileIntent_HasClipData— verifies ClipData set for single-file share (API 29+: not null, API <29: null)Share_MultipleFilesIntent_HasClipData— verifies ClipData set for multi-file share (API 29+: not null with 2 items, API <29: null)
- Prior agent review: A full prior review was found. Recommendation: APPROVE. PR's fix was selected as best candidate.

Summary
PR #34417 fixes a SecurityException that occurs on Android 10+ when using Share.RequestAsync to share files. The fix is correct, well-structured, and has been empirically verified: tests compile-fail without the fix (proving they catch the bug) and both pass on an Android emulator with the fix applied.
Root Cause
Android 10+ (API 29+) tightened URI permission enforcement. When sharing via a FileProvider content URI, the system's share chooser (uid=1000) must be granted read permission through the intent's ClipData. Without it:
SecurityException: Permission Denial: reading fileProvider uri content://...
requires the provider be exported, or grantUriPermission()
Two issues in the original code:
ClipDatawas not set on the share intent (required since API 29+ for URI permission propagation through the chooser)ActivityFlags.GrantReadUriPermissionwas missing from the chooser intent flags
Fix Quality
Assessment: ✅ Good
| Aspect | Evaluation |
|---|---|
| Correctness | ✅ ClipData.NewRawUri (single file) and manual ClipData construction (multi-file) are idiomatic Android patterns |
| API guard | ✅ IsAndroidVersionAtLeast(29) guard is correct; API <29 devices assert null (test handles both branches) |
| Testability | ✅ CreateShareFileIntent extracted as internal static enables device testing without launching an Activity |
| Test coverage | ✅ Two device tests verify ClipData is set for single-file and multi-file cases, with correct API-level branching |
| Code style | ✅ Clean, well-commented; using AndroidUri = Android.Net.Uri alias reduces ambiguity |
| Inline review | ✅ Copilot's concern about missing API guards in tests was raised and addressed by the author |
Code Notes
No issues found. The fix is minimal and targeted:
- Only
Share.android.cs(implementation) andShare_Tests.cs(device tests) are changed PlatformRequestAsync(ShareTextRequest)(text sharing) is unaffected — text sharing doesn't use FileProvider URIs so noGrantReadUriPermissionis needed there- The
ClipDataconstruction correctly handles the edge case wherecontentUris.Count == 1vs> 1with separate code paths matching Android's API expectations

Summary
PR #34417 fixes a SecurityException on Android 10+ when using Share.RequestAsync to share files via a FileProvider URI. The fix correctly adds ClipData to the share intent (both single-file and multi-file cases, guarded by API 29+) and adds ActivityFlags.GrantReadUriPermission to the chooser intent flags. Four independent fix alternatives were explored — 3 passed tests but none were preferable to the PR's approach for the reasons below.
Root Cause
Android 10+ (API 29+) requires ClipData on share intents for URI permission propagation through the system chooser. When an app calls startActivity() with a FileProvider content URI in EXTRA_STREAM but without ClipData, the system's share chooser (uid=1000) cannot read the URI and logs:
SecurityException: Permission Denial: reading fileProvider uri content://...
requires the provider be exported, or grantUriPermission()
Two issues in the original code:
ClipDatawas not set on the file share intentActivityFlags.GrantReadUriPermissionwas missing from the chooser intent flags
Fix Quality
Assessment: ✅ Good
| Aspect | Evaluation |
|---|---|
| Correctness | ✅ ClipData.NewRawUri (single) + manual ClipData (multi) are idiomatic Android patterns |
| API guard | ✅ IsAndroidVersionAtLeast(29) correctly matches test expectations (null on API < 29) |
| Testability | ✅ CreateShareFileIntent extracted as internal static enables device testing without launching Activity |
| Test coverage | ✅ Two device tests verify ClipData for single/multi-file cases with correct API-level branching |
| Code style | ✅ Clean extraction, well-commented, alias AndroidUri for clarity |
Minor observations (not blockers):
PlatformRequestAsync(ShareTextRequest)still lacksGrantReadUriPermissionon its chooser, but text shares don't use FileProvider URIs — not a bug.contentTypecan benullifFilesis empty, butClipDataonly reached whencontentUris.Count > 0;ClipDataaccepts null MIME gracefully.

MAKE SURE THIS PR IS TARGETING MAIN. !!!!!!! --> ### Issue Details - `Share.RequestAsync` logs `SecurityException` on Android 10+ ### Root Cause of the issue - Missing `ClipData` on the file share intent — Android 10+ uses `ClipData` (not `EXTRA_STREAM`) to propagate URI permission grants through the chooser - `chooserIntent.SetFlags(ClearTop | NewTask)` was missing `GrantReadUriPermission`, so the chooser process (share sheet UI, uid=1000) couldn't read the FileProvider URI to show preview thumbnails ### Description of Change <!-- Enter description of the fix in this section --> Enhancements to Android file sharing: * Ensured that `ClipData` is set on share intents for both single and multiple files, granting URI read permissions to receiving apps and preventing `SecurityException` on Android 10+ when accessing shared files. * Extracted the intent creation logic into a new `CreateShareFileIntent` method, making it easier to test without launching an activity. Test improvements: * Added unit tests for Android to verify that `ClipData` is correctly set for both single and multiple file share intents, ensuring shared URIs are accessible. Codebase maintenance: * Added missing `using System;` directive and aliased `AndroidUri` for clarity in `Share.android.cs`. * Updated test file imports to include necessary namespaces for file operations and storage. ### Issues Fixed <!-- Please make sure that there is a bug logged for the issue being fixed.
