Question

Answer 1

1. 首先你需要权限

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

2. 然后创建一个广播接收器

   import android.content.BroadcastReceiver;
   import android.content.Context;
   import android.content.Intent;
   
   public class Startup extends BroadcastReceiver {
   
       public Startup() {
       }
   
       @Override
       public void onReceive(Context context, Intent intent) {
           // start your service here
           context.startService(new Intent(context, SERVICE.class));
       }
   
   }
   

3. 在您的 list 中将此 BroadCast 接收器注册为

   <receiver android:name="YOUR_PACKAGE.Startup" >
       <!-- This intent filter receives the boot completed event -->
       <intent-filter>
           <action android:name="android.intent.action.BOOT_COMPLETED" />
       </intent-filter>
   </receiver>
   

Note: A service too is not guaranteed to run from device boot to device shut down, as in extreme cases the Android system may kill the service also to gain additional memory.
