Try:
Context context = MyClass.this.getBaseContext();

Where MyClass is the name of your class.

this breaks everything else...
errors at:
getContentResolver().openInputStream(imageUri)
and
context.setWallpaper(bgImage)

What are you 2 new errors?

What kind of class contains your onClickListener?

Does that new code properly get your Context?
--If not, you might need getContext() rather than getBaseContext()

at
getContentResolver().openInputStream(imageUri)

Unhandled exception type fileNotFoundException
quick fix: Surround with try/catch

at
context.setWallpaper(bgImage)

Unhandled exception type IOException
quick fix: Surround with try/catch

when i changed it to Context context = MyClass.this.getBaseContext(); this line no longer errors

here is more of my code... i'm pretty sure that my only problem is in actually setting the wallpaper, i can't find any good sources on the WallpaperManager... what i've found is that people still use setWallpaper even though it says its depreciated.
