Out of memory error on getDrawable()

Question

I want to get the current image set as the wallpaper in Android device and set it to the image view in my list after scaling it . What i am doing id this:

final WallpaperManager wm = WallpaperManager.getInstance(this);
final Drawable wallpaperDrawable = wm.getDrawable();
Bitmap bitmap = drawableToBitmap(wallpaperDrawable);
imageview.setImageBitmap(bitmap);

The drawableToBitmap Function is as follows:

public static Bitmap drawableToBitmap (Drawable drawable) {
    if (drawable instanceof BitmapDrawable) {
        return ((BitmapDrawable)drawable).getBitmap();
    }

    int width = drawable.getIntrinsicWidth();
    width = width > 0 ? width : 1;
    int height = drawable.getIntrinsicHeight();
    height = height > 0 ? height : 1;

    Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
    drawable.draw(canvas);

    return bitmap;
}

But i get this error :

@beginner, what you need to do here is resize the bitmap image, you will get this error if the image is too big. here is a question, you can see the person who asked the question is scaling the image down http://stackoverflow.com/questions/34661257/load-applications-icons-and-getting-outofmemory-exception-while-resizing/34661894#34661894 — Pankaj Nimgade, Jan 29 '16 at 08:37
@beginner, what is the size of image you are trying to render ? — Pankaj Nimgade, Jan 29 '16 at 08:38

Resize your image Bitmap

Bitmap bitmap = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.yourImageName);

Above line will get Bitmap from Drawable. No need to do anything apart from adding the above line to get a Bitmap from a Drawable.

int height = (bitmap.getHeight() * 512 / bitmap.getWidth());
Bitmap scale = Bitmap.createScaledBitmap(bitmap, 512, height, true);
imageView.setImageBitmap(scale);

I tried this, but still getting the same error : final WallpaperManager wm = WallpaperManager.getInstance(this); final Drawable wallpaperDrawable = wm.getDrawable(); Bitmap bitmap = drawableToBitmap(wallpaperDrawable); int height = (bitmap.getHeight() * 512 / bitmap.getWidth()); Bitmap scale = Bitmap.createScaledBitmap(bitmap, 512,height, true); imageview.setImageBitmap(scale); – beginner Jan 29 '16 at 08:30
decodeResource requires the id if the drawable image but i have the drawable image taken out from the getDrawable – beginner Jan 29 '16 at 08:59
It works but costs a lot of cpu power and causes shutters – Stanislav Kinzl May 09 '19 at 10:31

Whats your Logcat Throws

01-29 13:30:50.310: W/WallpaperManager(3281): java.lang.OutOfMemoryError

Thrown when a request for memory is made that can not be satisfied using the available platform resources. Such a request may be made by both the running application or by an internal function of the VM or Device .

Compress image before set to ImageView

Creates a new bitmap, scaled from an existing bitmap, when possible. If the specified width and height are the same as the current width and height of the source bitmap, the source bitmap is returned and no new bitmap is created.

Bitmap.createScaledBitmap(YourImageBitMap, 100, 50, true);

Reduces your images size .

Don't put drawables that are not vector drawables into DRAWABLE but into DRAWABLE-NODPI instead. Otherwise on some devices you are going to get OOME because they were scaled and had higher memory usage. Happens on Samsungs more

Drawable wallpaper = getApplicationContext().getWallpaper();

The wallpaper is a reference.

Bitmap.createBitmap might make OOM exception.

WindowManager source code:

// This is the final bitmap we want to return.
try {
Bitmap newbm = Bitmap.createBitmap(width, height,Bitmap.Config.ARGB_8888);
