`我正在使用 API 23，应用程序的最低 API 是 16。那么我应该怎么做才能修复错误
我尝试了壁纸管理器，但出现错误 这是代码
case R.id.button:
InputStream yeaaa =getResources().openRawResource(toPhone);
Bitmap Whatever = BitmapFactory.decodeStream(yeaaa);
WallpaperManager myWallpaper =WallpaperManager.getInstance(this);
try{
myWallpaper.setBitmap(Whatever);
} catch (IOException e) {
e.printStackTrace();
}
break;
