我无法从 BroadcastReceiver 获得启动服务

发布于 2024-12-20 16:27:34 字数 963 浏览 1 评论 0原文

当我的广播接收器触发警报时，我试图启动我的服务。我没有收到任何错误并且代码运行，但它没有启动我的服务，并且我没有收到任何错误。这可能是我的服务或清单中的问题吗？

我注意到，当涉及到意图和上下文时，我经常遇到问题。我试图阅读它，但我找不到一个可以很好地解释它的网站。有什么建议吗？

public class Alarm extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(1000);

        Intent myService = new Intent(BackgroundService.class.getName());
        context.startService(myService); 
    }
}

******************** 清单********

<service android:name=".BackgroundService" android:process=":remote">
    <intent-filter>
    <action android:name="se.davidsebela.ShutMeUp.BackgroundService" />
    </intent-filter>
</service>

<receiver  android:process=":remote" android:name="Alarm"></receiver>
</application>

I am trying to start my Service when an alarm gets triggered from my BroadcastReceiver. I am not getting any error and the code runs, but its not starting my service and I am not getting any errors. Could it be a problem that is in my Service or in the manifest?

I have noticed that I am often getting problems when it comes to Intents and Contexts. I have tried to read up on it, but I can't find a site that explains it in a good way though. Any suggestions?

public class Alarm extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(1000);

        Intent myService = new Intent(BackgroundService.class.getName());
        context.startService(myService); 
    }
}

****************** Manifest*******

<service android:name=".BackgroundService" android:process=":remote">
    <intent-filter>
    <action android:name="se.davidsebela.ShutMeUp.BackgroundService" />
    </intent-filter>
</service>

<receiver  android:process=":remote" android:name="Alarm"></receiver>
</application>

Intent myService = new Intent(BackgroundService.class.getName());

这只需一个动作就可以创建一个新的意图。该操作是BackgroundService 类的名称。当您使用 startService() 时，这将不起作用。

而是使用获取类和上下文作为参数的意图构造函数：

Intent myService = new Intent(context, BackgroundService.class);

Intent myService = new Intent(BackgroundService.class.getName());

This creates a new intent with just an action. The action is the name of the BackgroundService class. This won't work when you are using startService().

Rather use the intent constructor that gets a class and a context as arguments instead:

Intent myService = new Intent(context, BackgroundService.class);

明白了:-D 有点。现在我知道问题所在了。您建议的代码有效。

Intent myService = new Intent(context, TestService.class);
context.startService(myService);

但问题是我的服务已经在运行。本以为被杀掉了，结果只是定时器停止了，服务还在运行。因此，当执行上面两行时，它基本上什么也不做。

现在我必须找出如何真正杀死它:)

Got it :-D sort of. Now I know the problem. The code you suggested works.

Intent myService = new Intent(context, TestService.class);
context.startService(myService);

But the problem is that my Service is already running. I thought that it was killed, but only the timer was stopped and the service was still running. So when the two lines above are executed it basically dose nothing.

Now I have to find out how to really kill it :)
