Android中定时重启APP

前言

公司之前做的一个电视机上的播报应用（类似于银行的那种播报“请某某某到几号窗口”），现在要我做个定时重启

正题

整体思路：定时任务在服务里执行，当时间等于某个特定的值就重启
服务的代码：

/**
 * Created by mk_who on 2017/8/3/0003.
 */
public class MyService extends Service {

    private IBinder mBinder=new Binder();
    private Timer mTimer;
    private TimerTask mTimerTask;
    private Intent intent = new Intent("com.example.restart.RECEIVER"); 
    
    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

    @Override
    public void onCreate() {
        mTimer = new Timer();
        mTimerTask = new TimerTask() {
            @Override
            public void run() {
                new Thread(new Runnable() {
                    @Override
                    public void run() {
                        SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
                        String dateStr = sdf.format(new Date());
                        if (dateStr.equals("16:20")){
              
                            sendBroadcast(intent);//发送广播
                      
                        }
                    
                    }
                }).start();
            }
        };
        mTimer.schedule(mTimerTask,5000,59000);
        mTimer=null;
        mTimerTask=null;
    }
    @Override
    public void onDestroy() {
        super.onDestroy();
        mTimer.cancel();
        mTimerTask.cancel();
    }
}

开启服务的页面的部分代码：

private void startMyService() {
        Intent intent = new Intent(getApplicationContext(), MyService.class);
        
        bindService(intent, connServiceconn, BIND_AUTO_CREATE);
    }
    private Serviceconn connServiceconn = new Serviceconn();
    private class Serviceconn implements ServiceConnection {

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            Log.e("--------", "------开启服务成功---");
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {

        }
    }
    @Override
    protected void onResume() {
        super.onResume();
        startMyService();//开启服务
        filter.addAction("com.example.restart.RECEIVER");
        registerReceiver(reStartReceiver, filter);
    }

service跟activity通信的广播代码：

private BroadcastReceiver reStartReceiver = new BroadcastReceiver(){
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (action.equals("com.example.restart.RECEIVER")) {
                finish();
                Intent i = Main.this.getPackageManager()
                        .getLaunchIntentForPackage(Main.this.getPackageName());
                i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(i);
            }
        }
    };

当时是下午五点半（六点钟下班）接到的任务，着急下班吃饭（就是不想加班），就用了能想到的最简单的实现方式。
