我们正在使用Sinch voip api。有一个绑定服务，从应用程序启动开始，我们初始化服务中的sinch客户端，它始终在后台运行。我尝试将通知代码放在呼叫屏幕活动中，因为此活动将始终显示以接受呼叫。我的目标是能够点击通知并重新打开此调用活动，如whatsapp。

// for subclasses
}
protected void onServiceDisconnected() {
// for subclasses
}
protected SinchCallService.SinchServiceInterface getSinchServiceInterface() {
return mSinchServiceInterface;
}
}
我尝试了设置
之类的东西android:launchMode="singleTop"
如果我在CallScreenActivity上进行反投影并单击通知，则会打开MainAct而不是CallScreenActivity。如何让它打开CallScreenActivity？
我尝试了一个创建堆栈构建器并将其传递给挂起意图的解决方案，如下所示：
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(CallScreenActivity.class);
stackBuilder.addNextIntent(notificationIntent);
PendingIntent pendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
并且还改变了清单如下：
<activity
android:launchMode="singleTop"
android:name=".activity.calls.CallScreenActivity"
android:screenOrientation="portrait"
android:parentActivityName=".activity.main.MainAct">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".activity.main.MainAct"/>
</activity>
但上述更改会导致应用崩溃并出现以下错误：
07-06 23:38:52.353 9182-9182/com.app E/AndroidRuntime: FATAL EXCEPTION: main
java.lang.NullPointerException: Attempt to invoke interface method 'com.sinch.android.rtc.calling.CallClient com.sinch.android.rtc.SinchClient.getCallClient()' on a null object reference

所以如果我使用没有stackbuilder的代码，我按下主页按钮，然后按通知我的CallSCreenACtivity打开，但如果我按下CAllSCreenACtivity内的后退按钮，然后按主页按钮然后我按通知，它打开主而不是CallSCreenACtivity。即使在callcreenactivty上按下后退按钮，我的呼叫仍然是活动的。
此外，我注意到，在回拨CallScreenActivity但呼叫仍处于活动状态时，通知中显示的呼叫持续时间已停止刷新。
应用流程：
致来电者： - 当应用程序启动时，MainAct会启动，用户点击某个人的个人资料后会被带到ProfilesAct，在那里他按下呼叫按钮呼叫该人并被带到CallScreenActivity。
MainAct->ProfilesACt->CallScreenACt
对于接收者： - 应用程序在后台，调用到来，SinchCallService使IncomingCAllAct显示，当他接受调用时，他将被带到CallScreenActivity。
IncomingCallAct->CallSCreeenACtivity
或者可能是假设接收者已经在使用该应用，那么
any activity(could be chat activity, main acitivty etc)->IncomingCallAct->CallSCreeenACtivity

答案 0 :(得分：0)
没有必要在mainfest中将CallScreenActivity作为singletask或singletop，只需存储调用参数，如callid（帮助Sinch api识别特定的调用），在sharedpreferences或sqlite db中调用启动时间等，make通知意图如下：
Intent notificationIntent = new Intent(getApplicationContext(), CallScreenActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new NotificationCompat.Builder(getApplicationContext())
.setContentTitle("In call with " + otherusername)
.setSmallIcon(R.drawable.iconcall)
.setContentIntent(pendingIntent).build();
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(111 /* ID of notification */, notification);
只要我们传递了正确的callid，我们就可以通过点击通知来恢复通话。
