you can use executor running multitple tasks.

also check executorservice in below link

http://developer.android.com/reference/java/util/concurrent/executorservice.html

an alternative asynctask robospice. runs asynchronously.canhandle multiple spice requests. updates ui on ui thread. more details check below link

edit:

http://developer.android.com/reference/android/os/asynctask.html

check order of execution topic

quote above link

if want parallel execution, can invoke executeonexecutor(java.util.concurrent.executor, object[]) thread_pool_executor

starting honeycomb, tasks executed on single thread avoid common application errors caused parallel execution.
