Tour activity EditPhoto.java working perfectly in my API level 7 AVD,

            e.printStackTrace();
        }

        return true;
    }

}

i am posting my Layout and Manifest here ...

Layout editphoto.xml

and Manifest file ...

New Activity to display image ImageDisplayActivity.java (Image will be displayed when you will click on surface view)....

package x.y;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.widget.ImageView;

public class ImageDisplayActivity extends Activity {

    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        Bundle extras = getIntent().getExtras();
        setContentView(R.layout.anotherlayout);

        BitmapFactory.Options options=new BitmapFactory.Options();
        options.inSampleSize = 5;
        byte[] imageData = extras.getByteArray("imageData");
        Bitmap myImage = BitmapFactory.decodeByteArray(imageData , 0, imageData.length,options);


        ImageView imageView = (ImageView) findViewById(R.id.myPic);
        imageView.setImageBitmap(myImage);
    }   
}

and it's layout otherlayout.xml ...
