android获取当前壁纸并设置它

Question

我获取当前壁纸并将其转换为位图并再次将其转换为字符串base64并将其保存在sharedprefrences中并从shareprefrences获取壁纸并将其设置为壁纸，所有代码都在循环中，每5秒设置一次。在那里工作的每件事只有一个问题wallapeper设置正确，但是当它再次设置壁纸崩溃或缓慢破坏后再次设置。请看我的代码为什么壁纸慢慢慢慢崩溃。请帮我一些代码谢谢。

final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {

            @Override
            public void run() {

        final WallpaperManager wallpaperManager = WallpaperManager.getInstance(context);
        Drawable wallpaper_profile3 = wallpaperManager.getDrawable();
        Bitmap bitmap_profile3 = ((BitmapDrawable) wallpaper_profile3).getBitmap();

            ByteArrayOutputStream baos_profile3 = new ByteArrayOutputStream();
            bitmap_profile3.compress(Bitmap.CompressFormat.JPEG, 100, baos_profile3);
            final byte[][] b_profile3 = {baos_profile3.toByteArray()};
            String encodedImage_profile3 = Base64.encodeToString(b_profile3[0], Base64.DEFAULT);

            wallpaper_sharedprefrences_profile3 = context.getSharedPreferences(PREF_PROFILE3, Context.MODE_PRIVATE);
            SharedPreferences.Editor edit = wallpaper_sharedprefrences_profile3.edit();
            edit.putString(PROFILE2_WALLPAPER, encodedImage_profile3);
            edit.commit();

            load_wallpaper_profile3 = wallpaper_sharedprefrences_profile3.getString(PROFILE2_WALLPAPER, "");

            ByteArrayOutputStream baos2_profile3 = new ByteArrayOutputStream();
            final byte[][] b2_profile3 = {baos2_profile3.toByteArray()};
            b2_profile3[0] = Base64.decode(load_wallpaper_profile3 , Base64.DEFAULT);
            Bitmap bit_profile3 = BitmapFactory.decodeByteArray(b2_profile3[0], 0, b2_profile3[0].length);

                WallpaperManager wallpaper = WallpaperManager.getInstance(context);

                        try {
                            wallpaper.setBitmap(bit_profile3);
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
//                        wallpaper.suggestDesiredDimensions(width, height);
                    Toast.makeText(context, "Wallpaper Set", Toast.LENGTH_SHORT).show();

    handler.postDelayed(this, 5000);
            }
        }, 5000);
