ExecutionException and InterruptedException are two very different things. ExecutionException wraps whatever exception the thread being executed threw, so if your thread was, for instance, doing some kind of IO that caused an IOException to get thrown, that would get wrapped in an ExecutionException and rethrown. An InterruptedException is not a sign of anything having gone … Read more
To “re-interrupt” as a best practice: try{ //some code } catch (InterruptedException ie) { logger.error(“InterruptedException: “, ie); Thread.currentThread().interrupt(); } catch (ExecutionException ee) { logger.error(“ExecutionException: “,ee); } Usually, when a thread is interrupted, whoever is interrupting the thread, wants the thread to exit what it’s currently doing. However, make sure that you do NOT multi-catch: catch … Read more
Try Async Task or for your part of code. “AbstractQueuedSynchronizer” looks Synchronizing problem. public class Task extends AsyncTask<Void, Void, Void> { @Override protected void onPreExecute() { super.onPreExecute(); } protected Void doInBackground(Void… paths) { //here your code (approx from line 400 to 850) return null; } @Override protected void onPostExecute(Void result) { super.onPostExecute(result); } } for … Read more
Ignoring a checked exception is never considered to be safe. It may seem okay for you at the moment, but if any other programmer uses your code/API, they should expect the standard behaviour: Which is, the thread “reacting” to an interrupt call, but with whatever “reaction” the thread’s documentation describes. I mean it’s up to … Read more
You should generally NOT ignore the exception. Take a look at the following paper: Don’t swallow interrupts Sometimes throwing InterruptedException is not an option, such as when a task defined by Runnable calls an interruptible method. In this case, you can’t rethrow InterruptedException, but you also do not want to do nothing. When a blocking … Read more
What is the difference between the following ways of handling InterruptedException? What is the best way to do it? You’ve probably come to ask this question because you’ve called a method that throws InterruptedException. First of all, you should see throws InterruptedException for what it is: A part of the method signature and a possible … Read more
