Before this change, a start() call will wait for previous threads to finish. However, in ListenerMultiplexer.java in the framework, start(), stop(), and deliverListener() calls are contending for the same lock. Therefore, if a waiting start() is holding the lock, while the almost-finishing thread is also going to hold that lock for calling deliverListener(), a deadlock will happen. This CL moves the waiting logic into the new thread of the start() call, so that start() will return immediately. The new thread will wait for the old thread to finish, and then start the actual work. Bug: 299563185 Test: atest CtsLocationGnssTestCases Change-Id: Ic2993a6d82c24688fa98d26d336c85518c683cf6
