小贝子编程

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



我无法接受QuickBlox RTC Call。

以下是异常日志：

以下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，我尝试在服务中实现它。上面的代码写在服务中，并通过GreenRobot的事件总线触发。

这是我的呼叫代码：

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);

我发现这是由我自己的错误引起的。

将代码从示例转移到服务时，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);

这没关系。但是我没有在onStop（）方法中删除以下内容：

getActivity().unregisterReceiver(audioStreamReceiver);

这将导致崩溃。我没有设法捕获此事件，因为我的服务将立即重新启动并立即擦除所有日志。

我正在结束这个问题。
