When ANR is encountered for Launcher, a dialog box opens and then Launcher launches. Select "OK" to restart Launcher after restarting the launcher, the remaining keys will be deleted.
The problem arises in my development environment and is difficult to reproduce. Therefore, I am doing a test for this:
- Create a simple APK like Launcher and sleeping for a while in onCreat or onResume so that ANR appears
- Launch Launcher and press the key to enable ANR.
- after sleep, the view is usually displayed behind the ANR dialog box, select “OK” to restart the launcher, then the keys cannot be received, because the activity cannot be created.
- Throwing an event because there is no focused window or focused application.
The APK is used on Android4.0 and Android2.2 there are no problems in Android2.2, this seems like a problem on Android 4.03. The magazine comes for a real testing problem and emulates the release in 2.2, 4.03. Plus: I also modify the original Launcher2 and slept in onResume, it doesn’t have such a problem, but I can’t find any clues.
Any help is appreciated.
