在用户退出应用程序后保持后台服务处于活动状态 [英] keeping background service alive after user exit app

问题描述

我正在尝试创建一个服务，即使在用户从正在运行的进程菜单中关闭应用程序(通过将进程移出屏幕)后，它也会为我做后台作业.

I'm trying to create a service that will do background jobs for me even after the user closes the app from the running processes menu(by shifting process out of the screen).

我试图做的是通过如下声明在不同的进程中创建服务:

What I tried to do is create service in a different process by declaring it like this:

  <service
        android:name=".service.Service"
        android:enabled="true"
        android:icon="@drawable/ic_launcher"
        android:process=":my_process" >
  </service>

而 onStartCommand() 是:

and the onStartCommand() is:

    @Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return START_STICKY;
}

推荐答案

根据 Android 文档您可以通过使用属性来实现此行为:

According to the Android documentation you can achieve this behavior by using the attribute:

 android:isolatedProcess="true"

顺便说一句，我知道它没有回答问题，但它也可能对某些人有所帮助 - 最近，我发现了 Evernote 开发人员创建的一个很棒的第三方库.它的名字是 Android-Job，它的目标是创建在不同进程上运行的作业，并且可以成为即使在设备重启后也能再次激活，这真是太棒了.

By the way, I know that it's not answering the question but it might help some people as well - lately, I found out about a great third-party lib that Evernote developers have created. Its name is Android-Job and its aim is to create jobs that run on different processes and can become active again even after a device reboot, it's amazing.
