检测Whatsapp调用并暂停ExoPlayer

Question

我正在开发一个安卓音乐播放器应用程序.I只是想在电话到达时暂停，这已经被电话管理器所使用，但我也想检测Whatsapp呼叫和其他互联网呼叫.How来实现这一点。

这是我的代码，应该做哪些更改来检测internet呼叫，还可以暂停播放呼叫和播放呼叫结束。

private void player_manager_on_call() {
    // TODO Auto-generated method stub
    // Manage player on Call

    phoneStateListener = new PhoneStateListener() {

        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            if (state == TelephonyManager.CALL_STATE_RINGING)
            // Incoming // call: // Pause // music
            {

                try {

                    boolean is_playing = mediaController.Check_IsPlaying();
                    if (is_playing) {
                        Log.d("xiomi", "CALL_STATE_RINGING");

                        // Get details of song from sp

                        position = PlayerConstants.SONG_NUMBER;

                        data = PlayerConstants.SONGS_LIST.get(position);

                        Play_link = data.getPath();
                        Artist = data.getArtist() + "-" + data.getAlbum();
                        albumArt = UtilFunctions.getAlbumart(
                                getApplicationContext(), data.getAlbumId());
                        Log.e("albumArt", "albumArt " + albumArt);

                        mediaController.doPauseResume();
                        showControls();

                        // start notification service again for play

            } else if (state == TelephonyManager.CALL_STATE_IDLE) // Not in
                                                                    // //call:

    TelephonyManager mgr = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
    if (mgr != null) {
        mgr.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
    }

}

我将避免处理Android文档中的代码，所以我只会给您提供应该回答您问题的链接。

首先，您不需要自己检测来自不同应用程序的呼叫，您只需要注册广播接收器并对音频焦点的变化采取行动。
