title: Can't call ASyncTask from another ASyncTask
body: <p>I've looked at other questions and I failed to clarify my doubt as to call a task from another task, I have the following code:</p>
  
  <pre><code>protected List&lt;Plan&gt; doInBackground(String... params) 
      try {
          JSONParsePlans parseJSON = new JSONParsePlans();
          return parseJSON.execute(params[0], params[1], params[2]).get();
      } catch (InterruptedException e) {
          e.printStackTrace();
          return null;
      } catch (ExecutionExeption e) {
          e.printStackTrace();
          return null;
      }
  }
  </code></pre>
  
  <p>parseJSON is a task, when I run the program does nothing, not even called to task, it's like what Android omitted for security.</p>
