@hemantuno can you add more details on this error - what actions you performed when it happened, version of Android Studio, etc?

[hemantuno]

Run code on Samsung(Galaxy Tab A(2017) ) device using android studio 3.2.1. Very first time run app then above logs display.

[tiembo]

Does Sunflower work when you run it on an emulator?

[hemantuno]

Not try in emulator.

[tiembo]

Please try it in an emulator as to see if the error also happens there or only on the device.

[hemantuno]

Same error in emulator.

[tiembo]

I'm unable to reproduce this. Can you try Android Studio 3.3 and in a new emulator? Also try doing a "File -> Invalidate caches / Restart" in Android Studio.

[alashow]

I'm seeing this stack trace in my app. I'm using Android Studio 3.3, invalidated cache, running on an emulator. It's triggered after calling DataBindingUtil.setContentView(this, R.layout.activity):

Hi everyone - thanks for the error reports.

To help pinpoint the problem, please comment with the device you're using (even if it's an emulator), along with the OS version the device is running.

Hello everyone, I also faced this issue. How can i resolve it?

[timniko]

I also got this problem. Only thing I recently did was updating Android Studio to the latest version.

[demidrolk]

Got the same problem while rebuilding the same app on the same phone (one month ago it was working fine)

[marlonlom]

Whats the name of the class that is inaccesible?

b.h.i.u$b extended by class androidx.core.view.ViewCompat$5 is inaccessible

edit: Checking out the ViewCompat class file, at #2429:

v.setOnApplyWindowInsetsListener(new View.OnApplyWindowInsetsListener() {
  @Override
  public WindowInsets onApplyWindowInsets(View view, WindowInsets insets) {
    WindowInsetsCompat compatInsets = WindowInsetsCompat.wrap(insets);
    compatInsets = listener.onApplyWindowInsets(view, compatInsets);
    return (WindowInsets) WindowInsetsCompat.unwrap(compatInsets);
  }
});

Is something related to the 'insets' object that enforces us to use window insets in apps with android version <= Q ???

I believe this error occurred after I change the app name in string.xml file.

You mean intrusive, ugly, and log polluting?

[bryanwagner]

I have the same issue. After looking around, looks like this is a known bug in ViewCompat that's unlikely to be fixed. I found more information at https://stackoverflow.com/a/52954286/759719. If this is indeed a benign issue, the exception should be caught and logged at debug or trace level, rather than info level. This has a productivity impact on apps with clean logs, where a stack trace triggers alarm notifications. Unfortunately this is likely handled by a different Google team.

This error often occurs when you enable multidex support for your apps. You may read more about it here
