I'm seeing a bothersome change in behavior of the live wallpaper SDK in Android 2.2. Specifically, it's the windowToken parameter to WallpaperManager.sendWallpaperCommand(); in the docs it's described as "The window who these offsets should be associated with, as returned by View.getWindowToken()." Which sounds fine, but if the live wallpaper I'm trying to send a command to is the "main" one - on the home screen - what view should this be?
In 2.1, I could send a null for this parameter, and it worked fine - my live wallpaper got the command. In 2.2, the null produces a crash by the system. Here's a logcat trace, FWIW: E/WindowManager( 85): Window Session Crash E/WindowManager( 85): java.lang.IllegalArgumentException: Requested window null does not exist E/WindowManager( 85): at com.android.server.WindowManagerService.windowForClientLocked(WindowManagerService.java: 9244) E/WindowManager( 85): at com.android.server.WindowManagerService $Session.sendWallpaperCommand(WindowManagerService.java:6827) E/WindowManager( 85): at android.view.IWindowSession $Stub.onTransact(IWindowSession.java:345) E/WindowManager( 85): at com.android.server.WindowManagerService $Session.onTransact(WindowManagerService.java:6694) E/WindowManager( 85): at android.os.Binder.execTransact(Binder.java:288) E/WindowManager( 85): at dalvik.system.NativeStart.run(Native Method) Fortunately, this crash is invisible to the user, but that's small consolation as the command never reaches my wallpaper. Has anyone worked out how to get a window token for the home screen? Or any other way around this? Or any other way to send a message to the currently running live wallpaper?
