问题
When ANR occurs for Launcher,dialog pops up and the Launcher resume then. Select OK to restart Launcher after the launcher resume to respond, the rest keys will be dropped.
The problem occurs in my developing environment and it's hard to reproduce.So I do a test for this:
- Create a simple APK as Launcher, and sleep some time in onCreat or onResume to let the ANR occurs
- Start the Launcher and press key to let ANR occurs
- after sleep the view is normally shown behind the ANR dialog select OK to restart launcher, then keys can't be received because the activity can't created
- Dropping event because there is no focused window or focused application
The APK is used on Android4.0 and Android2.2 there is no problem in Android2.2, it looks like a problem on Android 4.03. Log are suppled for the real test issue and the emulate issue in 2.2, 4.03. Plus: I modify the original Launcher2 as well and sleep in onResume, It has no such issue but I can't find any clue.
Any help is appreciated.

回答1:
I add the attributes to the main activity in Launcher manifest
android:clearTaskOnLaunch="true"
android:stateNotNeeded="true"
The two attributes are in the original Launcher in Android which can solve this issue But why it works is still unknown.
