Firestore "DEADLINE_EXCEEDED" error in Release, but not in Debug mode #8378

Android application type

Classic Xamarin.Android (MonoAndroid12.0, etc.)

Affected platform version

VS 2022 17.7.4

Description

The Android app of a Xamarin.Android project I develop gives a "DEADLINE_EXCEEDED" error when run under "Release" configuration, but runs without any issues in "Debug" mode.

The error happens both on physical devices and when using the emulator. I also have tried different Android API levels (both on phones and on the emulator), but that makes no difference.

Steps to Reproduce

  1. Create an Android app that uses Firestore.
  2. Deploy the app under Release configuration.
  3. The "DEADLINE_EXCEEDED" error arises.

Did you find any workaround?

This is unlikely to be a problem with Xamarin.Android, the error appears to be server side. Please check some solutions suggested elsewhere:

If you still think this is caused by some issue in Xamarin.Android, please provide logs gathered by issuing the following commands at the developer prompt:

> adb shell setprop debug.mono.level default,assembly,timing=bare,mono_log_level=debug,mono_log_mask=all
> adb logcat -G 16M
> adb logcat -c
rem Run the application here and wait for the error to occur, then wait a few seconds more followed by:
> adb logcat -d > logcat.txt

And attach the resulting logcat.txt file here.

I'm afraid I didn't pay attention and I gave a wrong error. The right one is:
crc64[alphanumeric string].CrashlyticsException: Java.Lang.IncompatibleClassChnageError: no "Lcom/google/firebase/firestore/FirebaseFirestoreException$Code;" field "DEADLINE_EXCEEDED" in class "Lcom/google/firebase/firestore/FirebaseFirestoreException$Code;" or its super classes

no field in class or its superclass

Checking generated code in:

./generated/com.google.firebase.firebase-firestore/obj/Release/monoandroid12.0/generated/src/Firebase.Firestore.FirebaseFirestoreException.cs

Found code:

			// Metadata.xml XPath field reference: path="/api/package[@name='com.google.firebase.firestore']/class[@name='FirebaseFirestoreException.Code']/field[@name='DEADLINE_EXCEEDED']"
			[Register ("DEADLINE_EXCEEDED")]
			public static global::Firebase.Firestore.FirebaseFirestoreException.Code DeadlineExceeded {
				get {
					const string __id = "DEADLINE_EXCEEDED.Lcom/google/firebase/firestore/FirebaseFirestoreException$Code;";

					var __v = _members.StaticFields.GetObjectValue (__id);
					return global::Java.Lang.Object.GetObject<global::Firebase.Firestore.FirebaseFirestoreException.Code> (__v.Handle, JniHandleOwnership.TransferLocalRef);
				}
			}

gives a "DEADLINE_EXCEEDED" error when run under "Release" configuration, but runs without any issues in "Debug" mode.

This (Release crash, Debug OK) indicates that R8/proguard caused removal of that field (very high probability). Try adding proguard rules to the app.

Added a .cfg file to the Android project (Build Action: ProguardConfiguration) with the following rule:
-keep class com.google.firebase.** { *; }
No luck! Same error...

moljac commented Sep 27, 2023

-keep class com.google.firebase.** { *; }

OK. This would keep all Firebase stuff. Maybe too much.

Can you try -keepclassmembersand -keepclasseswithmembers

Something like:

# preserve private fields in all classes use
-keepclassmembers class * {
    private <fields>;    
}

Start with that and increase specificity until

-keepclassmembers class com.google.firebase.firestore.FirebaseFirestoreException.Code {
    private <fields>;    
}

maybe (note $):

-keepclassmembers class com.google.firebase.firestore.FirebaseFirestoreException$Code {
    public static <fields>;    
}

Some samples

BTW which version of Firestore do yo use?

@moljac

Actually after a couple of tries the error changed, so the rule worked. (Maybe a cached version of the app ran initially?)

Now the error is:
crc64[alphanumeric string].CrashlyticsException: Plugin.CloudFirestore.CloudFirestoreException: Failed to get document because the client is offline

I will address the issue of the generic rule I used after solving the new error. I will try to use the most specific one, but my priority is to fix the last error.

By the way, I use version 3.3.0.

-keepclassmembers class com.google.firebase.firestore.FirebaseFirestoreException$Code { <fields>; } works fine.

As for the new error, it is definitely an error that happens during linking. When I set the linking to "None" it vanishes. I'm not sure how to deal with it though.

@CostasAthan: reiterating @moljac 's comment, do you have full(er) adb logcat output?

In particular, this part of your most recent comment leaves me wanting more:

Fatal Exception: crc64[alphanumeric_string].CrashlyticsException: Plugin.CloudFirestore.CloudFirestoreException: Failed to get document because the client is offline.

  at (Inner Exception) Firebase.Firestore.FirebaseFirestoreException: Failed to get document because the client is offline.()

In particular, I want the full exception output for the nested FirebaseFirestoreException. This should be printed as part of the UNHANDLED EXCEPTION message which is printed as part of the .NET Android crash logging, but will not be part of the builtin Android crash logging. I suspect that your log information is from the Android crash logging output, not "full" adb logcat output.

How can I get the data you suggest? In Release mode I don't see any errors through the IDE and the error happens only in Release configuration.

CostasAthan commented Oct 3, 2023

Running the app on Debug mode with linking enabled I get the following 2 unhandled exceptions:

System.ArgumentException: 'Type 'MyApp.DatabaseFields+TableFields' does not have a default constructor
Parameter name: type'

Here is the line that causes the 1st one:

if (myDocument.ToObject<DatabaseFields>().myString1 == "string1")

That's the file that models the database's fields. Here is my code:

internal class DatabaseFields
{
    public class TableFields
    {
        public string myString1 { get; set; }

        public string myString2 { get; set; }
    }
}

When I hit the "Continue" button I get the following error:

System.TypeInitializationException: 'The type initializer for 'CreatorCache`1' threw an exception.'

All these happen when linking is enabled. Disabling the linking makes the errors to vanish.

CostasAthan commented Oct 6, 2023

A few things to add...

The error in Release mode happens also with linking set to "Sdk Assemblies Only", so I guess it does not come from nugget packages, right?

Furthermore, even though I have enabled debugging in the Release configuration ("Enable developer instrumentation (debugging and profiling)"), trying to follow @jonpryor suggestion, I get this message in Visual Studio:

Android application is running (debug is disabled in android project properties).

Anyway, I have enabled linking in Debug mode. I hope the results are equivalent. In this message I have listed the errors I get with Debug configuration when linking is enabled: #8378 (comment)

edit: The errors in Debug mode happen only when the linking is set to "Sdk and User Assemblies", in contrast with Release mode in which the error arises regardless if linking is set to "Sdk Assemblies Only" or "Sdk and User Assemblies".

@CostasAthan asked:

How can I get the data you suggest?

By using the adb command. Within Visual Studio, click Tools > Android > Android Adb Command Prompt…. This will open a new cmd.exe window which has adb in %PATH%.

Then, before launching your app, run:

adb logcat > log.txt

then run your app. Once your app has crashed, return to the cmd.exe window, and type Ctrl+C to exit adb logcat. You can then read or upload log.txt.

The linker and reflection don't always mix well. My assumption is that this expression:

myDocument.ToObject<DatabaseFields>()

involves Reflection, and tries to use the DatabaseFields+TableFields constructor. The linker doesn't know about this, and thus the linker has removed the constructor.

The fix for this is one of:

  1. Don't link that assembly, or
  2. "Somewhere" in code that is not linked away, use the DatabaseFields+TableFields constructor, a'la new TableFields(), or
  3. Tell the linker to preserve the constructor.

(3) can be done via custom attributes such as DynamicallyAccessedMembersAttribute or XML descriptors

System.TypeInitializationException: 'The type initializer for 'CreatorCache`1' threw an exception.

Similar to my other question regarding exceptions, the nested exception is hugely important, and is missing here. What exception did CreatorCache`1 throw? What's the message + callstack? Presumably this is another circumstance where Reflection is being used, and the linker has removed whatever CreatorCache`1 requires.
