推荐答案

您可以在启动时启动服务. 您的AndroidManifest.xml文件中需要以下内容:

you can start your service on boot. You need the following in your AndroidManifest.xml file:

1)在您的元素中:

 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

2)在您的元素中(一定要为您的BroadcastReceiver使用完全限定的[或相对]类名称):

2) In your element (be sure to use a fully-qualified [or relative] class name for your BroadcastReceiver):

<receiver android:name="com.example.MyBroadcastReceiver">  
<intent-filter>  
    <action android:name="android.intent.action.BOOT_COMPLETED" />  
</intent-filter>  

在MyBroadcastReceiver.java中:

In MyBroadcastReceiver.java:

  package com.example;

    public class MyBroadcastreceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent startServiceIntent = new Intent(context, MyService.class);
        context.startService(startServiceIntent);
    }
  }
