title: Toast is crashing Application, even inside thread
body: <p>I have an onClick event in my android app that triggers the following code but it keeps crashing my app. I put it in a thread only because i read that that's supposed to prevent crashing. Also ctx refers to the Activity's context (it's a variable I created in the activity set equal to this. I've read and tried several things. Any help would be awesome. Thanks!</p>
  
  <pre><code>Thread toastThread = new Thread() {
    public void run() {
      Toast alertFailure = Toast.makeText(ctx, "Login Failed", Toast.LENGTH_LONG);
      alertFailure.show();
    }
  };
  toastThread.start();
  </code></pre>
