I read many posts here and on other sites, but can not find the problem creating my Error:
I use an AsyncTask because I want to easily manipulate the UI Thread before and after Execution.
In doInBackground I create a ThreadPoolExecutor and execute Runnables.
If I only execute 1 Runnable with the Executor, there is no Problem, but if I execute another Runnable I get following Error:

I set up the ThreadPoolExecutor like this:
// numberOfPackages: Number of Runnables to be executed
public void initializeThreadPoolExecutor (int numberOfPackages)
{
int corePoolSize = Runtime.getRuntime().availableProcessors();
int maxPoolSize = numberOfPackages;
long keepAliveTime = 60;
final BlockingQueue workingQueue = new LinkedBlockingQueue();
executor = new ThreadPoolExecutor(corePoolSize, maxPoolSize, keepAliveTime, TimeUnit.SECONDS, workingQueue);
}
I have no clue, why it fails when starting the second Thread.
Maybe Memory Leaks?
Any Help appreciated.
Thanks in Advance
