BitmapFactory unable to decode stream. Fatal nullpointer error

I have problem with decode stream. I'm trying to put images from folder /MyApp/icons to imageView. I have a fatal error

05-11 22:21:22.319: E/BitmapFactory(7981): Unable to decode stream: java.io.FileNotFoundException: /MyWeather/icons/a04n.png: open failed: ENOENT (No such file or directory)

I tried set a "icons/.." , "/icons/.." and a lot of another options, but anyone not works.

public class Notifications extends Activity{



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notification);

        ImageView imageView1 = (ImageView) findViewById(R.id.imageView1);
        Bundle extras = getIntent().getExtras();
        String ikona = extras.getString("icon");

        Bitmap bm = BitmapFactory.decodeFile("MyWeather/icons/a"+ikona+".png");
        imageView1.setImageBitmap(bm);

    }

}

Could anyone tell me, how I can get this icon from this folder and set it in my imageView? Thanks. enter image description here

Put your folder in the root of project doesn't means it will put that folder to the root of your Android device...
Well, in your case, I suggest you to save files in assets folder and use AssetManager to load the file.

Here is example:

Put your "icons" folder into assets folder.

Use the following code to decode your image file:

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.notification);

    ImageView imageView1 = (ImageView) findViewById(R.id.imageView1);
    Bundle extras = getIntent().getExtras();
    String ikona = extras.getString("icon");

    AssetManager assetManager = getAssets();
    Bitmap bm;
    try {
        InputStream is = assetManager.open("icons/a"+ikona+".png");
        bm = BitmapFactory.decodeStream(is);    
    } catch (IOException e) {
        e.printStackTrace();
        // put your exception handling code here.
    }
    imageView1.setImageBitmap(bm);
}
