Hello,
i am trying to add center crop in my code but i get issue please help me to solve this.

here is my current codes,
//set wallpaper on Home Screen
private void setWallpaperToHomeScreen() {
relativeLayoutLoadMore.setVisibility(View.VISIBLE);
Glide.with(this)
.asBitmap()
.load(Config.ADMIN_PANEL_URL+"/images/"+arrayList.get(currentPosition).getImage_url())
.into(new CustomTarget() {
@RequiresApi(api = Build.VERSION_CODES.N)
@OverRide
public void onResourceReady(@nonnull Bitmap resource, @nullable Transition<? super Bitmap> transition) {

                    WallpaperManager wallpaperManager = WallpaperManager.getInstance(WallpaperDetailsActivity.this);
                    try {

                        DisplayMetrics metrics = new DisplayMetrics();
                        getWindowManager().getDefaultDisplay().getMetrics(metrics);
                        int height = metrics.heightPixels;
                        int width = metrics.widthPixels;
                        Bitmap bitmap = Bitmap.createScaledBitmap(resource,width,height, true);
                        wallpaperManager.getDesiredMinimumWidth();//returned 1280 on s3
                        wallpaperManager.getDesiredMinimumHeight();//also returned 1280 on s3
                        wallpaperManager.suggestDesiredDimensions(width, height);
                        wallpaperManager.setBitmap(bitmap,null, true, WallpaperManager.FLAG_SYSTEM);
                        new Handler().postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                Snackbar.make(rootLayout,"Wallpaper was set successfully",Snackbar.LENGTH_LONG).show();
                                relativeLayoutLoadMore.setVisibility(View.GONE);
                                showFullScreenAds();
                            }
                        }, Constant.DELAY_SET_WALLPAPER);
                    } catch (IOException e) {
                        e.printStackTrace();
                        relativeLayoutLoadMore.setVisibility(View.GONE);
                    }

                }
                @Override
                public void onLoadCleared(@Nullable Drawable placeholder) {

                }
    });
}

Code that i want add in my app
public static void setWallpaper(Context context, BitmapDrawable wallpaper) {

try {

        WallpaperManager wallpaperManager = WallpaperManager.getInstance(context);

                if(wallpaper != null) {

                            Bitmap bmp = wallpaper.getBitmap();

                                        DisplayMetrics metrics = new DisplayMetrics();

                                                    WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);

                                                                windowManager.getDefaultDisplay().getMetrics(metrics);

                                                                            int height = metrics.heightPixels;

                                                                                        int width = metrics.widthPixels;

                                                                                                    wallpaperManager.setWallpaperOffsetSteps(1, 1);

                                                                                                                wallpaperManager.suggestDesiredDimensions(width, height);

                                                                                                                            Bitmap bitmap = centerCropWallpaper(context, bmp, Math.min(wallpaperManager.getDesiredMinimumWidth(), wallpaperManager.getDesiredMinimumHeight()));

                                                                                                                                        wallpaperManager.setBitmap(bitmap);

                        int imageCenterWidth = scaledWidth /2;

                            int widthToCut = imageCenterWidth - deviceWidth / 2;

                                int leftWidth = scaledWidth - widthToCut;

                                    Bitmap scaledWallpaper = Bitmap.createScaledBitmap(wallpaper, scaledWidth, desiredHeight, false);

                                        return Bitmap.createBitmap(scaledWallpaper, widthToCut, 0, leftWidth, desiredHeight);

                                        }

please help me to add this my app
