        String[] filePath = { MediaStore.Images.Media.DATA };
        Cursor cursor = getContentResolver().query(pickedImage, filePath, null, null, null);

        String imagePath = cursor.getString(cursor.getColumnIndex(filePath[0]));


        cursor.close();
        Bitmap thumb = (BitmapFactory.decodeFile(imagePath));
        image.setImageBitmap(thumb);
    }
}


@Override
public void onClick(View v) {

    Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
