Android ProTip: AsyncTask info
Beginning with Android 3.0 (API level 11), an extra feature is available in AsyncTask
so you can enable it to run across multiple processor cores. Instead of calling execute()
you can specify executeOnExecutor() and multiple requests can be executed at the same time
depending on the number of cores available.
