Before resolving a boot search network slow problem, found that because the phone process up and then will be actively connected to rild, so to a certain extent, the phone process startup time will affect the speed of network status registration. When the phone process is properly advanced, you can advance the network registration time a little earlier so that th

Daemon_path corresponds to B2,b processFirst lock yourself, then add the Sync module notify_and_waitforThe above code is the above synchronization logicAfter the synchronization is complete, two processes simultaneously listens to each other's lock, one side hangs off the other party immediately can monitor hears. This scheme can be used to monitor each other's death status on 5.0+, because they are blocking methods, so there is no power consumption efficiency problem.Here's to say, Perhaps you
