手机重启后恢复报警经理 [英] Restore Alarm manager after phone reboot

问题描述

我建立一个小部件用于学习目的，它只是在那里我设定的更新间隔的配置活动。它工作正常，我可以创建它的多个实例。
但是当我重新启动报警经理停止电话，部件将不会更新。
某些搜索和google'ng后，我知道我必须添加一个BOOT完整的接收
但几次尝试后，我没有执行，因此任何人都有关于如何添加或部件的任何良好来源$ C ​​$ C例如一个我的想法。

i am building a small widget for learning purpose, it simply has an configuration activity where i set the update interval. it works normally and i can create multiple instance of it. but when i reboot the phone the alarm manager stops, and the widget won't update. after some search and google'ng i learned that i have to add a BOOT COMPLETE receiver but after several attempts i failed to implement so any one has an i idea about how to add that or any good source code example on widgets.

推荐答案

要做到在启动一些你根本看下面。

To do something at boot you simply do following.

首先在清单，这是正在申请加入标签：

First in the manifest, this is added under application tag:

    <receiver android:name="AlarmReceiver">
    <intent-filter>
        <action android:name="packagename.ACTION"/>
        <action android:name="packagename.ACTION2"/>
    </intent-filter>
</receiver>

<receiver android:name="BootSetter" >
    <intent-filter>
        <action
            android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

为了这个工作，你需要添加允许接收广播在清单与以下行：

In order for this to work you need to add permission to receive the Broadcast in the manifest with following line:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

然后你有一个类BootSetter：

Then you have a class BootSetter:

public class BootSetter extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Do your stuff
    }
}

有一个类似的帖子，虽然不是完全地相同的这里。这是关于运行每天中午报警。

There is a similar post, though not completly the same here. It's about running an alarm every day at noon.
