android 重启应用方式有几种？

1、使用AlarmManager定时重启：

AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);

Intent intent = new Intent(this, MainActivity.class);

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);

alarmManager.set(AlarmManager.RTC, System.currentTimeMillis() + 1000, pendingIntent);

2、使用android.os.Process.killProcess()方法：

android.os.Process.killProcess(android.os.Process.myPid());

3、adb 命令进行应用重启

停止: adb shell am force-stop 包名
启动: adb shell am start 包名/activity名(包名是软件的标识,Activity主要描述app的某个页面)

4、最有用代码应用定时重启，不需要看门狗。

    @SuppressLint("WrongConstant")
    fun restartApp(mm: MainActivity) {
        val oldintent: Intent = mm.getIntent()
        //System.out.println("OLD INTENT:"+oldintent.getAction());
        val intent =
            PendingIntent.getActivity(mm.getBaseContext(), 0, Intent(oldintent), oldintent.flags)
        val manager = mm.getSystemService(Context.ALARM_SERVICE) as AlarmManager
        manager[AlarmManager.RTC, System.currentTimeMillis() + 250] = intent
        Log.i(TAG,"------------执行重启应用")
        Process.killProcess(Process.myPid())
    }
