BitmapFactory.decodeResource returns null value

Question

I am tring to load bitmaps from an internal resource in a View object (the source itself is in "drawable" files).

the code is:

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.view.View;


public class BannerView extends View {



 private Bitmap m_Banner = null;

 public BannerView(Context context, AttributeSet attributeSet) {
  super(context, attributeSet);

  m_Banner = BitmapFactory.decodeResource(getResources(), R.drawable.banner);

 }
}

Why m_Banner value is null?

thank you in advance

I have the same problem too, but I've found that if I put the picture into drawable-ldpi, it works fine. I do not know why, but this worked for me.

Please make sure that all the sdk componenets (E.G Eclipse, Android SDK, SDK plug in for eclipse are all up to date).

my problem was that i was using R.drawable.clickCamera, but clickCamera was actually an XML drawable (for a button with selectable states), not an actual image. that was silly.

Check options parameter when calling BitmapFactory.decodeResource. It is third parameter of this method and have to be set to false for returning a bitmap.
