Buggy source:
@Override protected void onActivityResult(int request,int result,Intent intent){
  super.onActivityResult(request,result,intent);
  if (request == SELECT_PICTURE && result == RESULT_OK) {
    try {

      if (uri != null) {
        String[] columns={MediaColumns.DATA};
        Cursor cursor=getContentResolver().query(uri,columns,null,null,null);
        cursor.moveToFirst();
        int index=cursor.getColumnIndex(MediaColumns.DATA);
        if (index != -1) {
          fileName=cursor.getString(index);
        }
        cursor.close();
      }
      if (fileName == null) {

Fixed version (ground truth):

  super.onActivityResult(request,result,intent);
  if (request == SELECT_PICTURE && result == RESULT_OK) {
    try {
      Uri uri=intent.getData();
      String fileName=null, mimeType=null;
      if (uri != null) {
        String[] columns={MediaColumns.DATA};
        Cursor cursor=getContentResolver().query(uri,columns,null,null,null);
        cursor.moveToFirst();
        int index=cursor.getColumnIndex(MediaColumns.DATA);
        if (index != -1) {
          fileName=cursor.getString(index);
        }
        cursor.close();
      }
      if (fileName == null) {
        setStoppedState();
        new ErrorDialog("String_Node_Str","String_Node_Str",MITM.this).show();
      }
 else {
        if (mCurrentActivity != null)         mCurrentActivity.setVisibility(View.VISIBLE);
        mimeType=System.getImageMimeType(fileName);
        Toast.makeText(MITM.this,"String_Node_Str",Toast.LENGTH_LONG).show();
