opened on Jul 2, 2020

Steps to Reproduce

  1. Set your Android project as the startup project
  2. Select the Release configuration
  3. In your Android project settings, under Android Build > General, set the package format to aab
  4. Under Advanced, ensure x86 is enabled as a supported ABI
  5. Build and deploy your app to a simulator running Android 9.0 (Pie) - x86
  6. The app freezes on the splash screen (before OnCreate)
  7. Logs show the app is throwing a mono exception, crashing, and restarting

As a note, a crash does not occur on Android 7.1, 8.1, and 10.0.

Expected Behavior

The app does not crash on launch when using aab on Android 9.0.

Actual Behavior

The app crashes on Android 9.0 after a mono exception and appears to freeze on the launch screen.

    Is this related to typemaps?

    I don't know why using an app bundle on Android 9.0 would cause this.

    @codympearson do you see this problem on any app (even hello world) or just your app?

    Hi @jonathanpeppers, I have not tried with a hello world app, but I have seen this issue in two separate Xamarin.Forms applications I am working on currently (one significantly less complex than the other). If I use AAB in debug, both apps run on Android 9.0. Switching to release, AAB crashes on Android 9.0. I have ruled out the AndroidX packages, as the issue occurs on one project that has not migrated yet.

    @codympearson I tried your steps above with the Xamarin.Forms Shell template and it worked for me on an Android 9.0 x86 emulator.

    Is there something specific in your app causing this? Are you able to create a new project that shows the same problem?

    If you enable Mono debug logging for the running emulator via:

    adb shell setprop debug.mono.log debug,assembly,timing

    And relaunch the app, it might give more information in the log. Attach that here, thanks!

    @jonathanpeppers I've uploaded a repro project and log with the requested mono debug logging at the bottom of my post. I created a blank Xamarin.Forms app with Xamarin.Forms 4.6.0, switched the Android project to use AAB in release, ran it, and was able to reproduce the crash. Thanks for looking into this! Here's the interesting piece:

    Thanks, @codympearson I can reproduce the bug above now.

    @grendello when I do a diff between an .apk and the .aab the only file I've found that differs is libxamarin-app.so:

    libxamarin-app.so.zip

    Can you tell if there is something odd in here? The .NET assemblies and classes.dex are identical.

    @jonathanpeppers the libxamarin-app.so binaries are identical except for the different build id, which you noticed on Slack. The type maps are identical.

    After more testing, we can reproduce this issue in a "hello world" app:

    https://github.com/xamarin/xamarin-android/tree/master/samples/HelloWorld

    If you add <application android:extractNativeLibs="false" to AndroidManifest.xml. App bundles happen to use this setting.

    It seems to only occur on an x86 Android 9.0 emulator, the x86_64 emulator works.
