Answer 1

Doing this not working for you?

task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);

I was already doing this and the problem was still there, the problem was I was using AsyncTask to run long background tasks that do run forever, so the ThreadPoolExecutor's worker threads were already occupied.

In my case AsyncTask.THREAD_POOL_EXECUTOR (use debugger to get your executor properties) was having the ff properties:

maximumPoolSize = 3
largetsPoolSize = 2
corePoolSize =2 

So disabling one of the long running asyncTasks made my doInBackground code to run but that is not the right solution.

The right solution is I moved long running tasks into custom threads rather than using AsyncTask.
