android开机启动activity或service

    技术2022-05-14  0

    原理:

     

    一,注册一个broadcast receiver监听action为"android.intent.action.BOOT_COMPLETED"的intent

     

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

     

    <receiver android:name=".BootReceiver" >

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

     

    二,broadcast receiver代码中启动activity或service

     

    public class BootReceiver extends BroadcastReceiver {

     

    @Overridepublic void onReceive(Context context, Intent intent) { if(intent.getAction().equals( Intent.ACTION_BOOT_COMPLETED )){  Intent in = new Intent(context, MyActivity.class); in.setFlags( Intent.FLAG_ACTIVITY_NEW_TASK );   context.startActivity(in); }}

    }
