How to load a image from assets?

i need to load a image from assets to avoid a froyo 2.2.2 bug resizing POT images in some particular cases. The way to avoid it is loading the image files from assets dir.

I’m trying to do with this:

String imagePath = "radiocd5.png";
AssetManager mngr = context.getAssets();
// Create an input stream to read from the asset folder
InputStream is = null;
try {
is = mngr.open(imagePath);
} catch (IOException e1) { e1.printStackTrace();}

//Get the texture from the Android resource directory
//InputStream is = context.getResources().openRawResource(R.drawable.radiocd5);
Bitmap bitmap = null;
try {
//BitmapFactory is an Android graphics utility for images
bitmap = BitmapFactory.decodeStream(is);
} finally {
//Always clear and close
try {
is.close();
is = null;
} catch (IOException e) {}
}

But i am getting NullPointerException on the line is.close();

i capture a FileNotFoundException: radiocd5.png, but that file is on my assets directory :S

What am i doing bad? The file is called radiocd5.png and it is on the assets directory

You can follow my tutorials on displaying data from Assets: https://xjaphx.wordpress.com/2011/10/02/store-and-use-files-in-assets/

The sample with loading image and text to display.

I now added the relevant part of the provided link
(in case of earthquake or something) 😉 Taifun

// load image
try {
// get input stream
InputStream ims = getAssets().open("avatar.jpg");
// load image as Drawable
Drawable d = Drawable.createFromStream(ims, null);
// set image to ImageView
mImage.setImageDrawable(d);
}
catch(IOException ex) {
return;
}
