Another way, tested on android 2.1, is take the ID or Absolute path of the gallery last image, then you can delete the duplicated image.
It can be done like that:
/**
* Gets the last image id from the media store
* @return
*/
private int getLastImageId(){
final String[] imageColumns = { MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA };
final String imageOrderBy = MediaStore.Images.Media._ID+" DESC";
Cursor imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns, null, null, imageOrderBy);
if(imageCursor.moveToFirst()){
int id = imageCursor.getInt(imageCursor.getColumnIndex(MediaStore.Images.Media._ID));
String fullPath = imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA));
Log.d(TAG, "getLastImageId::id " + id);
Log.d(TAG, "getLastImageId::path " + fullPath);
imageCursor.close();
return id;
}else{
return 0;
}
}
And to remove the file:
private void removeImage(int id) {
ContentResolver cr = getContentResolver();
cr.delete(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, MediaStore.Images.Media._ID + "=?", new String[]{ Long.toString(id) } );
}
