恢复 activity 的通知已在后台使用 backpress
Notification to resume activity which has gone in background using backpress
我们正在使用 Sinch voip api。有一个在 app start 启动的绑定服务，我们在服务中初始化 sinch 客户端，它在后台总是 运行 。我尝试将通知代码放在呼叫屏幕 activity 中，因为此 activity 将始终显示接受呼叫。我的目标是能够像在 whatsapp 中一样单击通知并重新打开此调用 activity。

}
protected SinchCallService.SinchServiceInterface getSinchServiceInterface() {
return mSinchServiceInterface;
}
}
我试过设置
android:launchMode="singleTop"
如果我按下 CallScreenActivity 并单击通知，它会打开 MainAct 而不是 CallScreenActivity。如何让它打开CallScreenActivity？
我尝试了一种解决方案，即创建一个 stackbuilder 并将其传递给待定意图，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);
并且还更改了清单如下：
<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>
但上述更改导致应用程序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

因此，如果我使用没有 stackbuilder 的代码，然后按下主页按钮，然后按下通知，我的 CallSCreenACtivity 打开，但是如果我按下 CAllSCreenACtivity 内的后退按钮，然后按下主页按钮，然后按下通知，它打开主要活动而不是 CallSCreenACtivity。即使按下 callscreenactivty 上的后退按钮，我的通话仍然活跃。
我还注意到通知中显示的通话时长在 CallScreenActivity 上按下后停止刷新，但通话仍然有效。
应用程序流程：
来电者：-
当应用程序启动时，MainAct 启动，用户从那里点击某人的个人资料，然后被带到 ProfilesAct，在那里他按下呼叫按钮呼叫那个人，然后被带到 CallScreenActivity。
MainAct->ProfilesACt->CallScreenACt
对于接收者：-
应用程序在后台，来电，SinchCallService 使 IncomingCAllAct 显示，当他接受呼叫时，他被带到 CallScreenActivity。
IncomingCallAct->CallSCreeenACtivity
或者假设接收者已经在使用该应用程序，那么
any activity(could be chat activity, main acitivty etc)->IncomingCallAct->CallSCreeenACtivity

mainfest中的CallScreenActivity不需要做成singletask或者singletop，只需要将callid(帮助Sinchapi识别具体调用)，调用开始时间等调用参数保存在sharedpreferences 或 sqlite db，使通知意图如下：
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);
只要我们传递正确的callid，我们就可以通过点击通知恢复通话。

}
protected SinchCallService.SinchServiceInterface getSinchServiceInterface() {
return mSinchServiceInterface;
}
}
我试过设置
android:launchMode="singleTop"
如果我按下 CallScreenActivity 并单击通知，它会打开 MainAct 而不是 CallScreenActivity。如何让它打开CallScreenActivity？
我尝试了一种解决方案，即创建一个 stackbuilder 并将其传递给待定意图，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);
并且还更改了清单如下：
<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>
但上述更改导致应用程序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

因此，如果我使用没有 stackbuilder 的代码，然后按下主页按钮，然后按下通知，我的 CallSCreenACtivity 打开，但是如果我按下 CAllSCreenACtivity 内的后退按钮，然后按下主页按钮，然后按下通知，它打开主要活动而不是 CallSCreenACtivity。即使按下 callscreenactivty 上的后退按钮，我的通话仍然活跃。
我还注意到通知中显示的通话时长在 CallScreenActivity 上按下后停止刷新，但通话仍然有效。
应用程序流程：
来电者：- 当应用程序启动时，MainAct 启动，用户从那里点击某人的个人资料，然后被带到 ProfilesAct，在那里他按下呼叫按钮呼叫那个人，然后被带到 CallScreenActivity。
MainAct->ProfilesACt->CallScreenACt
对于接收者：- 应用程序在后台，来电，SinchCallService 使 IncomingCAllAct 显示，当他接受呼叫时，他被带到 CallScreenActivity。
IncomingCallAct->CallSCreeenACtivity
或者假设接收者已经在使用该应用程序，那么
any activity(could be chat activity, main acitivty etc)->IncomingCallAct->CallSCreeenACtivity

mainfest中的CallScreenActivity不需要做成singletask或者singletop，只需要将callid(帮助Sinchapi识别具体调用)，调用开始时间等调用参数保存在sharedpreferences 或 sqlite db，使通知意图如下：
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);
只要我们传递正确的callid，我们就可以通过点击通知恢复通话。
