ANDROID注册一个永久的广播接收机 [英] android register a permanent Broadcast Receiver

问题描述

我需要创建一个BroadcastReceiver在紧接每次执行特定任务的设备启动。此外，单击某个按钮时，接收机应该停止在开始启动。有人可以帮助我来管理？

I need to create a BroadcastReceiver which performs certain task immediately each time the device boots up. Also, when a certain button is clicked, the receiver should stop starting on boot. Can someone help me to manage that?

推荐答案

所有你需要解决你的问题的第一部分是让的BroadcastReceiver 它并宣布它在你的表现为：

All you need to solve the first part of your question is to make a BroadcastReceiver for it and declare it in your Manifest as:

<receiver android:name=".MyBootReceiver"
        android:enabled="true"
>
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <action android:name="android.intent.action.QUICKBOOT_POWERON" />
    </intent-filter>
</receiver>

在 QUICKBOOT_POWERON 是必要的不发 BOOT_COMPLETED 播出一些设备。 HTC设备喜欢用QuickBoot工具1代替。

The QUICKBOOT_POWERON is necessary for some devices that don't send the BOOT_COMPLETED broadcast. HTC devices like to use the quickboot one instead.

对于你的问题的第二部分，有一些不同的方式，你可以做到这一点。你可以简单地设置一个值共享preferences 你的接收器检测每次发射时间，并退出立即如果该值指示等。

For the second part of your question, there are a few different ways you could accomplish this. You could simply set a value in SharedPreferences that your receiver checks every time it fires, and exit immediately if the value dictates such.

您也可以禁用接收器code：

You could also disable the receiver in code:

getPackageManager().setComponentEnabledSetting( 
    new ComponentName( this, MyBootReceiver.class ),
        PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
        PackageManager.DONT_KILL_APP );

您可以使用相同的方法启用：

You can enable it using the same method:

getPackageManager().setComponentEnabledSetting( 
    new ComponentName( this, MyBootReceiver.class ),
        PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
        PackageManager.DONT_KILL_APP );

我不能确定这种方法的持久性。我在我的应用程序之一使用它，但它不是一个启动接收器，并且它没有在引导持续。你必须尝试它，如果你想要走这条路。

I am unsure of the persistence of this method. I use it in one of my apps, but it's not for a boot receiver, and it doesn't have to persist across boots. You'll have to experiment with it if you want to go that route.
