Question

我正在尝试通过Twilio视频通话提供本地视频通话体验。这是场景：

个人AAA呼叫个人BBB。
人员BBB没有打开应用程序，在后台或前景中，应用程序处于终止状态，甚至可能已锁定电话。
当来自AAA的呼叫到达时，将使用带有应答按钮的视频ui打开该应用程序。就像在WhatsApp，Google Duo，Skype中一样...

我们有FCM，并且正在收到推送通知。尝试在通话到达时立即打开视频通话接听按钮，而不单击通知，就像在Whatsapp，Google Duo ...（在Android手机中）

我们试图在后台运行一个带有套接字的服务。当向套接字发出传入呼叫事件时，套接字将监听传入的呼叫并打开VideoCallActivity。

这是我们最好的选择，但到目前为止没有成功。您将如何实现此功能？

所以我们已经找到了解决方案（当收到通知时，将应用程序置于前台），即使已经有一段时间了，我也要发布它：

FCM通知（firebase云消息传递通知）仅需要在通知中发送“数据”。因此，通知的JSON结构中没有Notification对象，只有数据。这样，通知便由您应用的FirebaseMessagingService.java类处理。请详细阅读以下内容，以了解如何处理两种FCM通知类型。 https://firebase.google.com/docs/cloud-messaging/android/receive https://firebase.google.com/docs/cloud-messaging/concept-options#notifications_and_data_messages

在FirebaseMessagingService.java类中，使用Intent启动VideoCall活动。不要忘记将此服务添加到Manifest.xml

        Intent intent = new Intent(this, VideoCallActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
        getApplicationContext().startActivity(intent);

在VideoCall活动中，确保在onCreate（）的开头具有以下代码：

// These flags ensure that the activity can be launched when the screen is locked.
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
        | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
        | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

// to wake up screen
PowerManager pm = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wakeLock = pm.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP), "TAG");
wakeLock.acquire();

// to release screen lock
KeyguardManager keyguardManager = (KeyguardManager) getApplicationContext().getSystemService(Context.KEYGUARD_SERVICE);
KeyguardManager.KeyguardLock keyguardLock = keyguardManager.newKeyguardLock("TAG");
keyguardLock.disableKeyguard();

使用适当的意图过滤器将VideoCallActivity添加到Manifest.xml中：

 <activity android:name=".ui.activities.video_call.VideoCallActivity" android:launchMode="singleTop" android:screenOrientation="portrait" android:theme="@style/AppTheme.NoActionBar"> <intent-filter>  <action android:name="VIDEO_CALLING" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity>

可选：要使手机响起并振动：

// For Incoming Call
// 1. declare
private MediaPlayer incomingCallMediaPlayer;
// .2 in onCreate, if I'm the person that's calling, ring the phone 
incomingCallMediaPlayer = MediaPlayer.create(this, R.raw.incoming);
incomingCallMediaPlayer.setLooping(true);
incomingCallMediaPlayer.start();
// 3. when I pick up, stop the player
incomingCallMediaPlayer.stop();

// I play R.raw.incoming if I'm being called.
// I play R.raw.outgoing when I'm calling.
// I understand if I'm the one calling from the number of participants in the "room" (this is a video call terminology) and by passing in a variable through the intent

// For Outgoing Call
// 1. declare
private MediaPlayer callingMediaPlayer;
// 2. in onCreate, if I'm being called, ring the phone
callingMediaPlayer = MediaPlayer.create(this, R.raw.outgoing);
callingMediaPlayer.setLooping(true);
callingMediaPlayer.start();
// 3. when another "participant" (this is a video call terminology) joins the "room" I stop playing the sound
callingMediaPlayer.stop();

// to Vibrate, add the code with the media players and stop vibrate with media players
