Is a good practice create anonymous AsyncTask for parallel small known freeze process? [closed]
Yes, but not the way you do it.
Remember that starting Honeycomb the default execution model of AsyncTasks is serial:
new AsyncTask<Void, Void, Void>() { .... .... }.execute(); <------ serial executionInstead use a thread pool executor:
new AsyncTask<Void, Void, Void>() { .... .... }.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, null); <------ parallel execution
