...or take care of threading properly - instead of Thread.sleep, use a
monitor and wait on it with a timeout. Here's the pseudo code
(catching InterruptedException omitted):
// in your main thread
// when you launch the secondary thread make sure it's running before
you do anything else
synchronized (secondaryThreadRunning)
{
secondaryThread = new ...
secondaryThread.start();
secondaryThreadRunning.wait();
}
// before you exit the app (e.g. onStop)
synchronized (secondaryThreadStopMonitor)
{
secondaryThreadShouldStop = true;
secondaryThreadStopMonitor.notify();
secondaryThread.join(); // wait for it to finish
}
// 1st line in the secondary thread's run()
// signal main thread we're up and running
synchronized (secondaryThreadRunning)
{
secondaryThreadRunning.notify();
}
// in the secondary thread where you want to wait and then post
synchronized (secondaryThreadStopMonitor)
{
secondaryThreadStopMonitor.wait(your timeout);
if (secondaryThreadShouldStop)
{
// break the loop (if you have one) and exit the thread (i.e.
let it return from run())
}
else
{
// timed out, post to your handler [1]
}
}
[1] You might get a spurious wake here, so it's best to track the
elapsed time manually
In any case, make sure you're not doing too much work, it seems that
you can simply use:
Handler.postDelayed(Runnable r, long delayMillis) and in your handler
do it again
