Preload images android

I have the following code:

@Override
public void surfaceCreated(SurfaceHolder holder) {
    Log.v(StartupActivity.TAG, "SURFACE CREATED");
    bitmaps = new HashMap<>();
    bitmaps.put("logo", BitmapFactory.decodeResource(getContext().getResources(), R.drawable.logo));
    displayLoadingBitmap();
    bitmaps.remove("logo");
    System.gc();
    ....
}

The surface is created immediately but my bitmap appears a little bit late. Is there a way to preload bitmap in for example StartupActivity and send it to the current Activity just to display it?

Yes, you can preload that bitmap in the start activity and pass it to the target activity.

In order to send that bitmap, since bitmaps implement Parceable, they can be serialized and passed to another activity.

StartUpActivity:

Intent intent = new Intent(this, TargetActivity.class);
intent.putExtra("image", bitmap);

TargetActivity:

Intent intent = getIntent();
Bitmap bitmap = (Bitmap) intent.getParcelableExtra("image");

Alternatively you're recommended to use Picasso library which handles all stuff you would need about caching and fetching images.
