java - 无需 READ_PHONE_STATE 权限即可使用 TelephonyManager

Question

我制作了一个音乐播放器应用程序，并在电话被调用时暂停歌曲，我使用此代码。

但这需要 READ_PHONE_STATE 权限，这可能会吓跑一些用户，所以我想知道是否可以通过另一种方式实现同​​样的事情而不需要此权限？

我的代码

private void callStateListener(){
        //incomingCallPause: checkbox value if user wants to pause when there is an incoming call.
        incomingCallPause = storageUtil.loadSwitchOnCall();
        mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        mPhoneStateListener = new PhoneStateListener(){
            @Override
            public void onCallStateChanged(int state, String incomingNumber) {
                switch (state) {
                    case TelephonyManager.CALL_STATE_OFFHOOK:
                        if (mediaPlayer != null){
                            pauseSong();
                        }
                        break;
                    case TelephonyManager.CALL_STATE_RINGING:
                        if (incomingCallPause && mediaPlayer != null) {
                            pauseSong();
                            NotificationBuilder(PlaybackStatus.PAUSED);
                            incomingCall = true;
                        }
                        break;
                    case TelephonyManager.CALL_STATE_IDLE:
                        if (mediaPlayer != null) {
                            if (incomingCall) {
                                incomingCall = false;
                                NotificationBuilder(PlaybackStatus.PLAYING);
                                if (!mediaPlayer.isPlaying()){
                                    mediaPlayer.start();
                                }
                            }
                        }
                        break;
                }
                super.onCallStateChanged(state, incomingNumber);
            }
        };

根据 Android 官方文档，您需要定义 list 权限才能使用 TelephonyManager。

需要 Manifest.permission.READ_PHONE_STATE
