title: AsyncTask run on one single thread in Android 2.3.3 (VERSION.SDK_INT = 10)
body: <p>Following the Android's document</p>
  <blockquote>
  <p>When first introduced, AsyncTasks were executed serially on a single background thread. Starting with DONUT, this was changed to a pool of threads allowing multiple tasks to operate in parallel. Starting with HONEYCOMB, tasks are executed on a single thread to avoid common application errors caused by parallel execution.</p>
  <p>If you truly want parallel execution, you can invoke executeOnExecutor(java.util.concurrent.Executor, Object[]) with THREAD_POOL_EXECUTOR.</p>

  <p>Is there any way to run AsyncTask on one single thread in Android 2.3.3 ? I intended to use executeOnExecutor but it only support for version sdk &gt; 11</p>
