Order of executionsuggest change
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.
If you truly want parallel execution, you can invoke
executeOnExecutor(java.util.concurrent.Executor, Object) with
SERIAL_EXECUTOR -> An Executor that executes tasks one at a time in serial order.
THREAD_POOL_EXECUTOR -> An Executor that can be used to execute tasks in > parallel.
Task task = new Task(); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) task.executeOnExecutor(AsyncTask.SERIAL_EXECUTOR, data); else task.execute(data);
