Exception NoSuchMethodError
With plugin version 9.6.1 I see the following crash for some users, I was not able to replicate it myself. Does anybody know if this is a bug or if I am doing something wrong?
Fatal Exception: java.lang.NoSuchMethodError: No static method e(Landroid/content/Context;)Landroidx/core/app/n; in class Landroidx/core/app/n; or its super classes (declaration of 'androidx.core.app.n' appears in /data/app/~~v8yhhqH2FHoMiGDXLA-pgQ==/androidx.test.tools.crawler-WljZg1GOGnOmmNq4rJSXqg==/base.apk) at com.dexterous.flutterlocalnotifications.FlutterLocalNotificationsPlugin.getNotificationManager(FlutterLocalNotificationsPlugin.java) at com.dexterous.flutterlocalnotifications.FlutterLocalNotificationsPlugin.cancelAllNotifications(FlutterLocalNotificationsPlugin.java:2) at com.dexterous.flutterlocalnotifications.FlutterLocalNotificationsPlugin.onMethodCall(FlutterLocalNotificationsPlugin.java:323) at io.flutter.plugin.common.MethodChannel$IncomingMethodCallHandler.onMessage(MethodChannel.java:17) at io.flutter.embedding.engine.dart.DartMessenger.invokeHandler(DartMessenger.java:18) at io.flutter.embedding.engine.dart.DartMessenger.lambda$dispatchMessageToQueue$0(DartMessenger.java:20) at io.flutter.embedding.engine.dart.DartMessenger.$r8$lambda$TsixYUB5E6FpKhMtCSQVHKE89gQ(DartMessenger.java) at io.flutter.embedding.engine.dart.DartMessenger$$InternalSyntheticLambda$0$ceffc6bae7d364cb48afaf1aaebd60bf9050360d0efb9035ebc54f0851df0a05$0.run(DartMessenger.java:12) at android.os.Handler.handleCallback(Handler.java:938) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loopOnce(Looper.java:201) at android.os.Looper.loop(Looper.java:288) at android.app.ActivityThread.main(ActivityThread.java:7839) at java.lang.reflect.Method.invoke(Method.java) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:548) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1003)
I'm having a similar issue too (Flutter 2.10.5 / Dart 2.16.2).
I uploaded my app to the Google Play Store and the Pre-launch report brought up this crash report:
java.lang.NoSuchMethodError: No static method e(Landroid/content/Context;)Landroidx/core/app/i; in class Landroidx/core/app/i; or its super classes (declaration of 'androidx.core.app.i' appears in base.apk)

Difficult for me to say what is going with a minimal app and steps to reproduce this. Things that come mind are if Proguard rules were configured correctly or perhaps that are other settings your apps needs based on your situation that may not be applicable to all apps e.g. enabling multidex
Thanks for your reply. I did check the Proguard rules and, as far as I can see, it's set up correctly I think. It's below, if want want to take a look - See if there's anything I've missed!
## Flutter wrapper

## Gson rules
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.

My Notifications class helper, in case it's useful. You'll see a few Crashlytics logs in there, as I was trying to determine where it was crashing. In each case, it was crashing in the init() function with the call to await flutterLocalNotificationsPlugin.initialize()

The rules look fine to me for the gson stuff. Not sure about the Flutter ones. One thing to note is logs point to an error where it looks like it can't resolve a method within the Android APIs themselves as opposed to something from this plugin so not something I can help with
@tnaseem providing Dart code won't help with these issues, which is why I mentioned a minimal app and that could be a link to a GitHub repo
No worries. I'll get it done after the weekend and see if it still happens. I'll need to run the test on Firebase TestLab to see if it shows up the crashes then. Only seems to happen on a few of their test devices.
This also started showing for me in crashlytics:

No code changes or new release, started appearing 6 days ago
Found this, looks related: https://issuetracker.google.com/issues/238234609
That's interesting, in Crashlytics mine appears on those same devices mentioned in the last comment on that thread. ie.:
- Galaxy S20 5G
- Galaxy 8
- AQUOS sense2 SH-01L
- Pixel 5

That's my comment 😅, I confirmed later that this only happens when the pre release report is running
Looks like this is to do with an issue outside of the plugin. Will keep this open for now so others know about this.
According to the comment at https://issuetracker.google.com/issues/237785592#comment96, this has been fixed by the Google team so will close this
