问题 I've very newly gotten into Android development, and decided that my first conquest on this fresh field would be to grasp how the phone reacted to incoming calls. A little googling later led me to http://www.compiletimeerror.com/2013/08/android-call-state-listener-example.html#.Vi3Ren4vfwM (so my code shares a striking resemblance to his/hers). My main (and only) activity looks like this: import android.app.Activity; import android.content.Context; import android.os.Bundle; import android

问题 A few people over the past decade have asked similar questions but none have ANY answers. I need to write an android app that collects and stores RSRP, RSRQ, CINR, and Cell ID. The answers need to be as accurate as the phones hardware allows (I am testing on Samsung Galaxy S5) because I need to do post processing statistics with those values.

问题 I implemented a PhoneStateListener how stops audio if you are called and starts it again after you finished. When i exit my app by finish() the PhoneStateListener seems to be still active. After finishing a call the music starts to play. Even if I set the listener=null in onDestroy() it keeps working... 回答1: Quoting the documentation for listen() on TelephonyManager: To unregister a listener, pass the listener object and set the events argument to LISTEN_NONE (0). You must do this before your
