实现 Android 应用在开机时自启动

16lz 2021-01-23

[代码] BootReceiver.java

view source

print ?

`01`	`public` `class` `BootReceiver` `extends` `BroadcastReceiver {`

`02`	`private` `PendingIntent mAlarmSender;`

`03`	`@Override`

`04`	`public` `void` `onReceive(Context context, Intent intent) {`

`05`	`// 在这里干你想干的事（启动一个Service，Activity等），本例是启动一个定时调度程序，每30分钟启动一个Service去更新数据`

`06`	`mAlarmSender = PendingIntent.getService(context,` `0,` `new` `Intent(context,`

`07`	`RefreshDataService.class),` `0);`

`08`	`long` `firstTime = SystemClock.elapsedRealtime();`

`09`	`AlarmManager am = (AlarmManager) context`

`10`	`.getSystemService(Activity.ALARM_SERVICE);`

`11`	`am.cancel(mAlarmSender);`

`12`	`am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstTime,`

`13`	`30` `` `60` `` `1000, mAlarmSender);`

14 }

15 }

[代码] 我们只需要在应用程序配置文件AndroidManifest.xml中注册这个Receiver来监听系统启动事件

view source

print ?

`1`	`<receiver` `android:name=".service.BootReceiver">`

`2`	`<intent-filter>`

`3`	`<!-- 系统启动完成后会调用-->`

`4`	`<action` `android:name="android.intent.action.BOOT_COMPLETED">`

`5`	`</action>`

`6`	`</intent-filter>`

`7`	`</receiver>`
