Is a good practice create anonymous AsyncTask for parallel small known freeze process? [closed]

Answer 1

Yes, but not the way you do it.

Remember that starting Honeycomb the default execution model of AsyncTasks is serial:

  new AsyncTask() {
         ....
         ....
  }.execute(); <------ serial execution

Instead use a thread pool executor:

  new AsyncTask() {
         ....
         ....
  }.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, null); <------ parallel execution
