Android openURI(...) not working on Android 11

Issue details

Android’s openURI is not working on Android 11 anymore. Calling openURI(...) does nothing. There is no error thrown.

Version of LibGDX and/or relevant dependencies

Latest stable release 1.9.13. The Android project has to be set to Android 11 (30).

Suggestion for Code Fix

A quick test showed the following code works. The live wallpaper flag needs to be set. Also, does this really need to run via UI thread as in libGDX’s example?

try {
   // open with the correct activity if any 
   startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
   return true;
}
catch (Exception e) {
   // ... log error...
   return false;
}

Please select the affected platforms

• Windows

Ah found it, it is not precaution but to make openUri threadsafe: https://github.com/libgdx/libgdx/pull/59#issuecomment-9296572 I don’t see much benefit in having a UI operation threadsafe though.

[MrStahlfelge]

I was able to reproduce this with a fresh emulator, too. The code @noblemaster gave in the OP works for me, too, or a slightly different variant:

	public boolean openURI (String URI) {
		final Uri uri = Uri.parse(URI);
		try {
			Intent intent = new Intent(Intent.ACTION_VIEW, uri);
			// LiveWallpaper and Daydream applications need this flag
			if (!(app.getContext() instanceof Activity)) {
				intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
			}
			app.startActivity(intent);
			return true;
		} catch (ActivityNotFoundException e) {
			return false;
		}
	}

According to stackoverflow, using the queries is needed when you need to know if there are applications, but not start them. We don’t have the situation here, and I am sure runOnUiThread is not needed. It was not introduced because of crash reports but from the beginning, probably out of precaution (5ef9a9ef)
