VS2019 16.2 Preview3 - 9.4.0.34 - My app crashes on Startup on Android 4.4 #3314

michaldobrodenka · 2019-07-02T08:00:50Z

Steps to Reproduce

Xamarin Android app with support libraries
Deploy to Phone/Emulator with Android 4.4 on Release & AOT
Crash

Since it seems related to resources, I've tried aapt1/2, Multidex On/Off (before this release Multidex was a must). My app has inherited Application class. On newer android emulators/phones app starts and runs without problems.

Expected Behavior

App start

Actual Behavior

Crash

Same issue...

jonathanpeppers · 2019-07-05T14:20:26Z

@michaldobrodenka or @Abesoddy can you provide the full adb logcat output?

If it happened on your splash screen, can you make a small sample app I can try to see this?

jonathanpeppers · 2019-07-05T14:33:35Z

Ok, I was able to reproduce it with a new Xamarin.Forms Master/Detail template and a Android 4.4 / API 19 emulator.

It appears to be something related to aapt2, unchecking this box solved the issue for me:

It could also be related to this React Native issue where they are seeing the exact same error message/same API level: oblador/react-native-vector-icons#457

Fixes: dotnet#3314 Create a new Xamarin.Forms project using aapt2, you will encounter a crash on startup for API 19 devices: android.content.res.Resources$NotFoundException: File res/drawable/abc_vector_test.xml from drawable resource ID #0x7f080058 at android.content.res.Resources.loadDrawable(Resources.java:2096) at android.content.res.Resources.getDrawable(Resources.java:700) at android.support.v4.content.ContextCompat.getDrawable(ContextCompat.java:360) at android.support.v7.widget.AppCompatDrawableManager.getDrawable(AppCompatDrawableManager.java:198) at android.support.v7.widget.AppCompatDrawableManager.getDrawable(AppCompatDrawableManager.java:186) at android.support.v7.widget.AppCompatDrawableManager.checkVectorDrawableSetup(AppCompatDrawableManager.java:753) at android.support.v7.widget.AppCompatDrawableManager.getDrawable(AppCompatDrawableManager.java:191) at android.support.v7.widget.TintTypedArray.getDrawableIfKnown(TintTypedArray.java:85) at android.support.v7.app.AppCompatDelegateImplBase.(AppCompatDelegateImplBase.java:128) at android.support.v7.app.AppCompatDelegateImplV9.(AppCompatDelegateImplV9.java:149) at android.support.v7.app.AppCompatDelegateImplV11.(AppCompatDelegateImplV11.java:29) at android.support.v7.app.AppCompatDelegateImplV14.(AppCompatDelegateImplV14.java:54) at android.support.v7.app.AppCompatDelegate.create(AppCompatDelegate.java:202) at android.support.v7.app.AppCompatDelegate.create(AppCompatDelegate.java:183) at android.support.v7.app.AppCompatActivity.getDelegate(AppCompatActivity.java:519) at android.support.v7.app.AppCompatActivity.onCreate(AppCompatActivity.java:70) at com.taphome.offline.SplashActivity.n_onCreate(Native Method) at com.taphome.offline.SplashActivity.onCreate(SplashActivity.java:29) at android.app.Activity.performCreate(Activity.java:5231) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2148) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2233) at android.app.ActivityThread.access$800(ActivityThread.java:135) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1196) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:136) at android.app.ActivityThread.main(ActivityThread.java:5001) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:793) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:609) at dalvik.system.NativeStart.main(Native Method) Java.Lang.RuntimeException: File res/drawable/abc_vector_test.xml from drawable resource ID #0x7f080058 ---> Org.XmlPull.V1.XmlPullParserException: Binary XML file line #15: invalid drawable tag vector Reviewing the logs, there was a missing `--no-version-vectors` flag? The Xamarin.Android.Support.Vector.Drawable NuGet was setting this value: Target _XamarinAndroidSupportVectorDrawableArgs AndroidResgenExtraArgs = --no-version-vectors Unfortunately the logic for passing this flag to aapt2 was happening *too soon*, at this point `$(AndroidResgenExtraArgs)` is blank: <AndroidAapt2LinkExtraArgs Condition=" '$(_AndroidUseAapt2)' == 'True' And $(AndroidResgenExtraArgs.Contains('--no-version-vectors')) And !($(AndroidAapt2LinkExtraArgs.Contains('--no-version-vectors'))) ">--no-version-vectors $(AndroidAapt2LinkExtraArgs) </AndroidAapt2LinkExtraArgs> The simple solution here is to move this property at the beginning of `_UpdateAndroidResgen` and the problem is solved. I added a test verifying that we are getting the `--no-version-vectors` flag for both aapt and aapt2.

cassionandi · 2019-07-05T18:03:01Z

I had this problema even with debug mode. Yesterday I solved by uninstalling all "support" packages anda reinstalling.

jonathanpeppers · 2019-07-05T18:53:36Z

If you are specifically getting:

android.content.res.Resources$NotFoundException: File res/drawable/abc_vector_test.xml from drawable resource ID #0x7f080058

Then the command-line invocation of aapt/aapt2 needs the --no-version-vectors switch.

To workaround you can either:

Disable aapt2 (aapt1 seems to work fine)
Set <AndroidAapt2LinkExtraArgs>--no-version-vectors</AndroidAapt2LinkExtraArgs> in your csproj

I don't how reinstalling NuGet packages would fix it, unless you removed the Xamarin.Android.Support.Vector.Drawable NuGet package.

cassionandi · 2019-07-06T21:40:28Z

the project don't have Xamarin.Android.Support.Vector.Drawable NuGet package.

michaldobrodenka · 2019-07-09T09:42:30Z

Ok, I've created minimal test app. In fact, it is just new project from VS template. It doesn't start on Android 4.4. I tryied --no-version-vectors , aapt1/2, Release or Debug.

Just run into this issue on Samsung with Android 4.4 device

Using:

Visual Studio Community 2019 for Mac: Version 8.4.4 (build 91)
Xamarin.Android: Version: 10.1.3.7 (Visual Studio Community)
Xamarin.Forms: 4.3.0.947036
AAPT2 enabled

Adding <AndroidAapt2LinkExtraArgs>--no-version-vectors</AndroidAapt2LinkExtraArgs>to the .csproj seems to fixed the issue.

I had the same issue, and adding <AndroidAapt2LinkExtraArgs>--no-version-vectors</AndroidAapt2LinkExtraArgs>to the .csproj fixed my issue.
