android - saving image picked from gallery for future use

Question

Hey i have been looking for a while now. the following code picks the image from the android gallery and shows it in an imageView. but heres the thing, everytime the app is closed and restarted the has to be picked again. i would like to know how i can edit the following to save the image for good in the imageView.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();

        ImageView imageView = (ImageView) findViewById(R.id.imgView);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }


}

The only thing that the user is picking is the path of the picture. So if you save the path to SharedPreferences, then everytime the app is started, you can use your existing code, but just change where you get the path:

String picturePath = PreferenceManager.getDefaultSharedPreferences(this).getString("picturePath", "");
if(!picturePath.equals(""))
{
   ImageView imageView = (ImageView) findViewById(R.id.imgView);
   imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}

EDIT: This is a complete method you can use in OnCreate:

String picturePath = PreferenceManager.getDefaultSharedPreferences(this).getString("picturePath", "");
if(!picturePath.equals(""))
{
   ImageView imageView = (ImageView) findViewById(R.id.imgView);
   imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
else {
   selectImage();
}

In select image use your current code to start the picking activity, then in onActivityResult use this:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        PreferenceManager.getDefaultSharedPreferences(this).edit().putString("picturePath", picturePath).commit();
        cursor.close();

        ImageView imageView = (ImageView) findViewById(R.id.imgView);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }
