由于 org.webrtc.PeerConnection.setRemoteDescription 空指针异常，无法接受 QuickBlox RTC 调用

Question

我无法接受 QuickBlox RTC 呼叫。

这是异常日志：

    at android.os.Handler.dispatchMessage(Handler.java:95)
    at android.os.Looper.loop(Looper.java:211)

这是我的呼叫接受代码：

            Integer myId = QBChatService.getInstance().getUser().getId();
            ArrayList<Integer> opponentsWithoutMe = new ArrayList<>(this.currentSession.getOpponents());

            opponentsWithoutMe.remove(new Integer(myId));
            opponentsWithoutMe.add(this.currentSession.getCallerID());
            List<QBUser> qbUserList = new ArrayList<>();
            for (int opponentId : opponentsWithoutMe) {
                qbUserList.add(new QBUser(opponentId));
            }

            SettingsUtil.setSettingsStrategy(qbUserList, PreferenceManager.getDefaultSharedPreferences(mContext), this);

            Intent intent = new Intent(mContext, QuickBloxCallActivity.class);
            intent.putExtra(Keys.QB_CONFERENCE_CALL_TYPE, this.currentSession.getConferenceType().getValue());
            intent.putExtra(Keys.QB_CALL_OPPONENT_NAME, getString(R.string.qb_dafault_opponent_name));
            intent.putExtra(Keys.QB_CALL_OPPONENT, this.currentSession.getOpponents().get(0));
            intent.putExtra(Keys.QB_START_CALL_ACTIVITY_REASON, QuickBloxCallActivity.StartCallActivityReason.INCOMING_CALL.ordinal());

            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);

            Map<String, String> userInfo = new HashMap<>();
            userInfo.put("key", "value");

            this.currentSession.acceptCall(userInfo);

与SDK中提供的示例不同，我尝试在Service中实现它。上面的代码写在一个Service中，通过GreenRobot的EventBus触发。

这是我的通话代码：

QBRTCSession session = QBRTCClient.getInstance(mContext).createNewSessionWithOpponents(
                        opponentIdList, event.getQbConferenceType());

                SettingsUtil.setSettingsFromPreferences(PreferenceManager.getDefaultSharedPreferences(mContext), this);
                initCurrentSession(session);

                ringtonePlayer.play(true);

                Intent intent = new Intent(mContext, QuickBloxCallActivity.class);
                intent.putExtra(Keys.QB_CONFERENCE_CALL_TYPE, session.getConferenceType().getValue());
                intent.putExtra(Keys.QB_CALL_OPPONENT_NAME, getString(R.string.qb_dafault_opponent_name));
                intent.putExtra(Keys.QB_CALL_OPPONENT, session.getOpponents().get(0));
                intent.putExtra(Keys.QB_START_CALL_ACTIVITY_REASON, QuickBloxCallActivity.StartCallActivityReason.OUTGOING_CALL.ordinal());

                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);

                Map<String, String> userInfo = new HashMap<>();
                userInfo.put(Keys.QB_USER_INFO_MAP_CALLER_NAME, event.getCallerName());

                this.currentSession.startCall(userInfo);

Answer 1

我发现这是我自己的错误造成的。

将代码从样本转移到服务时，我在 onStart() 中删除了以下代码：

intentFilter = new IntentFilter();
intentFilter.addAction(AudioManager.ACTION_HEADSET_PLUG);
intentFilter.addAction(AudioManager.ACTION_SCO_AUDIO_STATE_UPDATED);
audioStreamReceiver = new AudioStreamReceiver();
getActivity().registerReceiver(audioStreamReceiver, intentFilter);

没关系。但是我没有在 onStop() 方法中删除以下内容：

getActivity().unregisterReceiver(audioStreamReceiver);

这会导致崩溃。我没能捕捉到这个事件，因为我的服务会立即重启并立即清除所有日志。

我正在关闭这个问题。
