Unable To Convert Vector Drawable To Bitmap Drawable In Android

I am trying to convert a bitmap to byte array in which i have taken an vector drawable image to bitmap and then i have converted it to byte array but when i open the application it

Solution 1:

You can try this. It works fine with me.

private BitmapDescriptor bitmapDescriptorFromVector(Context context, @DrawableResint vectorDrawableResourceId) {
    Drawablebackground= ContextCompat.getDrawable(context, R.drawable.ic_map_pin_filled_blue_48dp);
    background.setBounds(0, 0, background.getIntrinsicWidth(), background.getIntrinsicHeight());
    DrawablevectorDrawable= ContextCompat.getDrawable(context, vectorDrawableResourceId);
    vectorDrawable.setBounds(40, 20, vectorDrawable.getIntrinsicWidth() + 40, vectorDrawable.getIntrinsicHeight() + 20);
    Bitmapbitmap= Bitmap.createBitmap(background.getIntrinsicWidth(), background.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
    Canvascanvas=newCanvas(bitmap);
    background.draw(canvas);
    vectorDrawable.draw(canvas);
    return BitmapDescriptorFactory.fromBitmap(bitmap);
}

Solution 2:

You cannot cast VectorDrawable to BitmapDrawable. They don't have a parent-child relationship. They both are direct subclasses of Drawable class.

to get a bitmap from drawable, you will need to create a Bitmap from the drawable metadata.

Probably something like this in a separate method,

try {
    Bitmap bitmap;

    bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), BITMAP_CONFIG);

    Canvascanvas=newCanvas(bitmap);
    drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
    drawable.draw(canvas);
    return bitmap;
} catch (OutOfMemoryError e) {
    // Handle the errorreturnnull;
}
