Android Twilio 视频通话，唤醒应用程序并将其置于前台

Question

我正在尝试使用 Twilio 视频通话提供原生视频通话体验。场景如下：

AAA 称 BBB。
人BBB没有打开应用，在后台或前台，应用处于被杀死状态，phone甚至可能被锁定
当 AAA 打来电话时，应用打开时会显示视频 ui 并带有接听按钮。就像在 WhatsApp、Google Duo、Skype...

我们有 FCM 并正在接收推送通知。试图在来电时打开视频通话接听按钮，而不是点击通知，就像在 Whatsapp 中一样，Google Duo...（在 Android phones 中）

我们试图在后台打开一个套接字服务运行。当传入呼叫事件发送到套接字时，套接字将侦听传入呼叫并打开 VideoCallActivity。

这是我们最好的选择，但到目前为止还没有成功。您将如何实现此功能？

所以我们已经找到了这个解决方案（当通知到达时，将应用程序调到前台）并且我发布它虽然已经有一段时间了：

FCM通知（firebase云消息通知）只需要在通知中发送“data”即可。所以通知的 JSON 结构中没有 Notification 对象，只有数据。通过这种方式，通知由您应用的 FirebaseMessagingService.java class 处理。请详细阅读以下内容以了解如何处理 2 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 class 中，启动带有 Intent 的视频通话 activity。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 activity 中，确保在 onCreate() 的开头有以下代码：

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

使用适当的 intent-filter 将 VideoCallActivity 添加到 Manifest.xml：

<!-- Video Call -->
<activity
    android:name=".ui.activities.video_call.VideoCallActivity"
    android:launchMode="singleTop"
    android:screenOrientation="portrait"
    android:theme="@style/AppTheme.NoActionBar">
    <intent-filter>
        <!-- Note: these actions are notification actions -->
        <action android:name="VIDEO_CALLING" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

可选：要使 phone 响铃和振动：

// 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 bypassing 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
//
