我们计划发布基于Twilio Voice SDK的Android应用更新。我们的客户希望获得更原生的体验，他们可以直接看到屏幕接受或拒绝来电（就像Skype / Whatsapp / Viber / Line等），而不是点击通知然后点击对话框。此外，这也应该在锁定屏幕上工作。
截至目前，我已成功在我的应用中打开活动并显示接受或拒绝按钮。它适用于应用程序处于前台或后台时。这是实现这一目标的代码片段。我修改了VoiceFirebaseMessagingService.java中的notify（）方法，以便在每次调用onMessageRecived进行来电通知时显示活动。
private void notify(CallInvite callInvite, int notificationId) {
String callSid = callInvite.getCallSid();
if (callInvite.getState() == CallInvite.State.PENDING) {
soundPoolManager.playRinging();
System.out.println("Disabling keyguard and accquiring wake lock");
Intent intent = new Intent(this, OnCallActivityNew.class);
intent.setAction(OnCallActivityNew.ACTION_INCOMING_CALL);
intent.putExtra(OnCallActivityNew.INCOMING_CALL_NOTIFICATION_ID, notificationId);
intent.putExtra(OnCallActivityNew.INCOMING_CALL_INVITE, callInvite);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent =
PendingIntent.getActivity(this, notificationId, intent, PendingIntent.FLAG_ONE_SHOT);
/*
* Pass the notification id and call sid to use as an identifier to cancel the
* notification later
*/
Bundle extras = new Bundle();
extras.putInt(NOTIFICATION_ID_KEY, notificationId);
extras.putString(CALL_SID_KEY, callSid);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_call_end_white_24px)
.setContentTitle(getString(R.string.app_name))
.setContentText(callInvite.getFrom() + " is calling.")
.setAutoCancel(true)
.setExtras(extras)
.setContentIntent(pendingIntent)
.setGroup("test_app_notification")
.setOngoing(true)
.setColor(Color.rgb(214, 10, 37));
notificationManager.notify(notificationId, notificationBuilder.build());
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtras(extras);
globalintent = intent;
new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
@Override
public void run() {
startActivity(globalintent);
}
},2000);
} else {
SoundPoolManager.getInstance(this).stopRinging();
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
/*
* If the incoming call was cancelled then remove the notification by matching
* it with the call sid from the list of notifications in the notification drawer.
*/
StatusBarNotification[] activeNotifications = notificationManager.getActiveNotifications();
for (StatusBarNotification statusBarNotification : activeNotifications) {
Notification notification = statusBarNotification.getNotification();
Bundle extras = notification.extras;
String notificationCallSid = extras.getString(CALL_SID_KEY);
if (callSid.equals(notificationCallSid)) {
notificationManager.cancel(extras.getInt(NOTIFICATION_ID_KEY));
} else {
sendCallInviteToActivity(callInvite, notificationId);
}
}
} else {
/*
* Prior to Android M the notification manager did not provide a list of
* active notifications so we lazily clear all the notifications when
* receiving a cancelled call.
*
* In order to properly cancel a notification using
* NotificationManager.cancel(notificationId) we should store the call sid &
* notification id of any incoming calls using shared preferences or some other form
* of persistent storage.
*/
notificationManager.cancelAll();
}
}
}
此外，在OnCallActivityNew.java的onCreate（）中，我提到了以下代码。
@Override
protected void onCreate(Bundle savedInstanceState) {
System.out.println("on create of activity is called for oncallactivitynew");
super.onCreate(savedInstanceState);
KeyguardManager kgm = (KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE);
boolean isKeyguardUp = kgm.inKeyguardRestrictedInputMode();
KeyguardManager.KeyguardLock kgl = kgm.newKeyguardLock("OnCallActivityNew");
if(isKeyguardUp){
kgl.disableKeyguard();
isKeyguardUp = false;
}
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Tag");
wl.acquire();
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN |
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON,
WindowManager.LayoutParams.FLAG_FULLSCREEN |
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
setContentView(R.layout.activity_on_call);
coordinatorLayout = (CoordinatorLayout) fin
..... ///more code below to add listener to different buttons
}
现在唯一的问题是，当手机被锁定时，此活动会打开并调用onDestroy（），我无法显示接受和拒绝按钮的屏幕。
我想要的行为就是拥有一种机制，即使在锁定屏幕上，也可以像我上面提到的应用程序那样接听电话。
我知道这是一个与Android工作方式有关的问题，但是你们这方面的任何帮助都会非常感激。我相信人们会从这次讨论中受益。
答案 0 :(得分：0)
我能够按照this answer中的步骤进行视频通话。
关于打开屏幕的代码，请尝试使用我的代码，让我知道它是否适合您。如果不是这样，您会知道问题出在其他地方，因为此代码可在我测试过的android设备上运行：
