android-broadcastreceiver

问题 I'm building an app that will listen for incoming SMS messages, perform some potentially long running operations and send back a reply if some conditions are met. I've got the listening part working using a BroadcastReceiver , but I'm not sure how/where to perform the potentially long running operations. The Android Developer Documentation states that After onReceive(), the system can kill the process at any time to reclaim memory, and in doing so, it terminates the spawned thread running in

问题 I have two separate apps. The first sends out two different kinds of Broadcasts. The second one waits for this broadcast from App #1 and uses the broadcast to decide what activity to launch. What I'm confused about is this: It seems to me that App #2 (the receiving app) shouldn't necessarily require a default activity since the activity it launches depends on the broadcast received from App #1. But, if a default activity is not defined in App #2, it can't run and throws: Error running app:

问题 I'm trying to be able to start music playback from my app when the headset buttons are clicked while my app is stopped. I can use MediaSession.Callback onMediaButtonEvent() or the now deprecated registerMediaButtonEventReceiver() to listen for media button click WHILE my app is playing music, but if I pause the music for a minute, with my Activity and playback Service still running, and then I press the headset button, I see that I have lost the ability to receive the media button broadcast.
