推荐答案

如果你看看在<一个href=\"http://developer.android.com/reference/android/content/Context.html#setWallpaper%28java.io.InputStream%29\"相对=nofollow>官方文档，你会发现，这个方法去$ P $因为pcated API 5 键，你应该使用<一个href=\"http://developer.android.com/reference/android/app/WallpaperManager.html#setBitmap%28android.graphics.Bitmap%29\"相对=nofollow> WallpaperManager.setBitmap（）代替

If you take a look at the official docs, you will find, that this method is deprecated since API 5 and you should use WallpaperManager.setBitmap() instead.
