Are you calling notify() from inside sendRequest()?
If so, it's the same thread, and notify has nothing to do. http://developer.android.com/reference/java/lang/Object.html#notify() Causes *a thread which is waiting on this object's monitor* (by means of calling one of the wait() methods) to be woken up >From looking at the code you posted, there is no thread waiting on the lock because you only have one worker thread, and when it's calling notify it's, well, calling notify and not waiting on a wait(). For debugging, set a breakpoint at lock.notify, and use the DDMS thread monitor or the debugger window to examine your threads. You might want to look at this package, which provides higher-level concurrency classes, and try to find one that fits what you're trying to do: http://developer.android.com/reference/java/util/concurrent/package-summary.html ( ThreadPoolExecutor?
