startForeground（）不显示我的通知 [英] startForeground() does not show my Notification

问题描述

我试图让我的服务在前台运行。我试图用这个例子（请认准节的在前台运行的服务的），但 startForeground（）实际上并没有显示我的通知。而没有异常被抛出。为了使它显示，我需要使用 NotificationManager 喜欢这里 的解释。随着 NotificationManager 我的通知工作，但我不知道我的服务终止后，这个无声电话的前景 startForeground（）。

I am trying to make my Service running in foreground. I tried to use this example (please look for the section "Running a Service in the Foreground"), but startForeground() does not actually show my notification. And no exceptions is thrown. To make it shown, i need to use NotificationManager like here explained. With NotificationManager my notification works, but i'm not sure that my Service is foreground after this "silent" call to startForeground().

什么是错的？

修改：我只是测试此示例项目应该表现出 startForeground（） ，但它不工作！我使用的API v7.0的，我无论在模拟器和真实设备（SE的Xperia新）进行了测试。通知将不会出现。

EDIT: I just tested this sample project that should demonstrate startForeground(), but it does not work! I use API v7.0, i tested it both on emulator and real device (SE Xperia Neo). Notification does not appear.

EDIT2 ：如果我试图调用 setForeground（）然后我得到了一个警告 setForeground：无视旧的API调用。

EDIT2: if i try to call setForeground() then i got a warning setForeground: ignoring old API call.

我还试图用 startForegroundCompat（）这里描述，但效果是absolutelly相同。检查我的服务使用前景 ActivityManager.RunningServiceInfo 描述这里，和我看到我的服务的不可以前景。

I also tried to use startForegroundCompat() as described here, but effect is absolutelly the same. I check if my service is foreground using ActivityManager.RunningServiceInfo as described here, and i see that my service is not foreground.

推荐答案

我只注意到 startForeground（）不显示通知图标，如果 ID 参数设置为 0 ...

I just noticed that startForeground() doesn't show the notification icon if the id parameter is set to 0...

startForeground(0, notification); // Doesn't work...

startForeground(1, notification); // Works!!!

我希望它可以帮助别人停留在此。

I hope that it could help someone stuck on this.
