What I am doing is this: I have an app that changes wallpaper automaticly. If the user changes it manually using a different aplication I would like to notice it and ask the users if he/she wants to add that new wallpaper to the list in my application There is only a broadcast for when a wallpaper image changes: http://developer.android.com/reference/android/content/Intent.html#ACTION_WALLPAPER_CHANGED To do what you want, you will need to have more logic to use

I'm running into an issue with my program when trying to crop an image selected by the user from their gallery. The issue so far only appears when running on a Droid X, as running on the original moto Droid works fine. Basically the issue occurs as the cropping intent is being run. Once the user crops the photo and clicks the save button, it replaces the wallpaper on the main screen with the cropped image that was saved! It does not do this on the moto droid, or emulators. Below is the code for cropping and saving the picture to the SD card: @Override public void onActivityResult(int

Is there a way to programatically get all the android system wallpapers? I know how to get the current one, via WallpaperManager , and then save it to disk. But I want to know if there is a way to access all the pictures that act as system wallpaper included with the O.S.

On stock Android the wallpapers are located in Launcher2.apk:res/drawable- somedpi . On my devices they were in the drawable-hdpi folder, but

I'm having an orientation issue with a Live Wallpaper that I wrote. Basically the canvas will rotate depending on the application opened above it. I tested this and realized that the onSurfaceChanged() method is firing when I return to the home screen from a previously opened application who's orientation was changed. I suppose a better question would be, why does my Live Wallpaper Surface Change when an application is opened and it's orientation changed? Is there a way to prevent my Live Wallpaper orientation from ever changing? Thanks, hope that makes sense? You can handle screen orientation
