title: getting context in AsyncTask
body: <p>I am trying to get the context in my AsyncTask of the class called Opciones(this class is the only one that call that task) but I don't know how to do it, I saw some code like this:</p>
  
  <pre><code>      protected void onPostExecute(Long result) {
  
      Toast.makeText(Opciones.this,"Subiendo la foto. ¡Tras ser moderada empezara a ser votada!: ", Toast.LENGTH_LONG).show(); 
  }
  </code></pre>
  
  <p>But it doesn't work for me it says: <code>"No enclosing instance of the type Opciones in scope"</code></p>
