杀应用

问题描述

我想经过10秒杀我的应用程序，我要开始的服务，让杀招后杀应用程序。但是，这code后10秒关注。为什么呢？

  AlarmManager alarmMgr =（AlarmManager）getSystemService（Context.ALARM_SERVICE）;
意向意图=新意图（这一点，service_MyService.class）;
intent.setAction（杀）;
的PendingIntent的PendingIntent = PendingIntent.getBroadcast（这一点，0，意向，0）;
日历时间= Calendar.getInstance（）;
time.setTimeInMillis（System.currentTimeMillis的（））;
time.add（Calendar.SECOND，10）;
alarmMgr.set（AlarmManager.RTC_WAKEUP，time.getTimeInMillis（），的PendingIntent）;
 

解决方案

在您的code您发送一个广播意图

  PendingIntent.getBroadcast（这一点，0，意向，0）;
 

这只能启动一个BroadcastReceiver，而不是服务。但是，你正在使用正确的意图，因为AlarmManager无法叫醒一个服务，只有广播接收器-S。

您应该创建一个BroadcastReceiver，而不是一种服务，替换此行：

 意向意图=新意图（这一点，service_MyService.class）;
 

这一行

 意向意图=新意图（这一点，KillerBroadCastReceiver.class）;
 

，然后在你的类KillerBroadCastReceiver你杀的应用程序。

不过，如果你想杀死一段时间后应用，更好的解决方案是使用一个处理器。下面是一个例子：

 公共类VeryFirstActivity延伸活动{
    处理器mKillerHandler;    公共无效的onCreate（...）{
        mKillerHandler =新的处理程序（）;
        mKillerHandler.postDelayed（新的Runnable（）{
           公共无效的run（）{
               VeryFirstActivity.this.finish（）;
           }
        }，10000）; //10秒
    }
}
 

I want to kill my app after 10 second, I want to start service that kill app after getting Kill Action. But this code noting after 10 second. Why?

AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, service_MyService.class);
intent.setAction("Kill");
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,intent, 0);
Calendar time = Calendar.getInstance();
time.setTimeInMillis(System.currentTimeMillis());
time.add(Calendar.SECOND, 10);
alarmMgr.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(),pendingIntent);

解决方案

In your code you are sending a broadcast intent

PendingIntent.getBroadcast(this, 0,intent, 0);

Which can only start a BroadCastReceiver and not a service. However, you are using the right intent, because AlarmManager can not wake up a services, only BroadCastReceiver-s.

You should create a BroadCastReceiver instead of a service, and replace this line:

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

with this line

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

and then in your KillerBroadCastReceiver class you kill the app.

However if you want to kill the app after some time, a better solution is to use a Handler. Here is an example:

public class VeryFirstActivity extends Activity {
    Handler mKillerHandler;

    public void onCreate(...) {
        mKillerHandler = new Handler();
        mKillerHandler.postDelayed(new Runnable() {
           public void run() {
               VeryFirstActivity.this.finish();
           }
        }, 10000); // 10 seconds
    }
}
