Some times we may require to select multiple images from gallery. So using the following method you will be able to select multiple images. Additionally it will also remove gallery app dependency.
It may not be sufficient method as I need to maintain two array in this activity, but it could vary on requirements. Please comment if you have any suggestion in code.

Update: need more features? see my open source project
Update: Please remove code that closes cursor. As this will not work in Android 4.0 and newer.
Test 2 :
Get all gallary image and store it in parse.com table
Simple use following java file :
public class AndroidCustomGalleryActivity extends Activity {
private int count;
private Bitmap[] thumbnails;
private boolean[] thumbnailsselection;
private String[] arrPath;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
final String orderBy = MediaStore.Images.Media._ID;
Cursor imagecursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,
null, orderBy);
int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);
this.count = imagecursor.getCount();
this.thumbnails = new Bitmap[this.count];
this.arrPath = new String[this.count];
this.thumbnailsselection = new boolean[this.count];
for (int i = 0; i < this.count; i++) {
imagecursor.moveToPosition(i);
int id = imagecursor.getInt(image_column_index);
int dataColumnIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA);
thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail(
getApplicationContext().getContentResolver(), id,
MediaStore.Images.Thumbnails.MICRO_KIND, null);
arrPath[i]= imagecursor.getString(dataColumnIndex);
Bitmap image = thumbnails[i];
ByteArrayOutputStream stream = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] data = stream.toByteArray();
ParseFile imgFile = new ParseFile (“Image”, data);
imgFile.saveInBackground();
//Info in Parse Dashboard
ParseObject imageObj = new ParseObject (“Image”);
imageObj.put(“Image”, imgFile);
imageObj.saveInBackground();
Toast.makeText(getApplicationContext(),”over”,Toast.LENGTH_LONG).show();
}
imagecursor.close();
}
}
it store all your gallary image on your parse.com table.
