BOOT_COMPLETED意图行动广播不能正常工作 [英] broadcasting of BOOT_COMPLETED intent action does not work properly

问题描述

我有几个动作的接收器类监听，但它不能赶上 android.intent.action.BOOT_COMPLETED 的行动。我做错了什么？这里是我的清单文件：

 ＆LT;使用-SDK安卓的minSdkVersion =7/＆GT;
＆LT;使用-权限的Andr​​oid：名称=android.permission.RECEIVE_BOOT_COMPLETED/＆GT;
    ！＆LT;  - ＆LT;接收器的Andr​​oid版本：NAME =OtherReceiver。＆GT;
        ＆LT;意向滤光器＆gt;
            ＆lt;作用机器人：名称=android.intent.action.BOOT_COMPLETED/＆GT;
    ＆所述; /意图滤光器＆gt;
    ＆所述; /接收机GT  - →;
    ＆LT;接收器的Andr​​oid版本：NAME =com.myApp.Ap preceiver安卓权限=android.permission.RECEIVE_BOOT_COMPLETED＆GT;
        ＆LT;意向滤光器＆gt;
            ＆lt;作用机器人：名称=android.intent.action.BOOT_COMPLETED/＆GT;
             ＆lt;作用机器人：名称=android.intent.action.PACKAGE_ADDED/＆GT;
             ＆lt;作用机器人：名称=com.myApp.wifitimer/＆GT;
            ＆lt;作用机器人：名称=android.intent.action.PACKAGE_REPLACED/＆GT;
            ＆lt;数据机器人：计划=包机器人：路径=com.myApp/＆GT;
    ＆所述; /意图滤光器＆gt;
    ＆LT; /接收器＆GT;
 

，因为它可以看出我再次加入许可的接收器内，并在接收器的名称获得的类的全名作为这样的答案建议。
这里是广播接收器类：

  @覆盖
公共无效的onReceive（背景为arg0，意图ARG1）{

    串动作1 = arg1.getAction（）;

    如果（action1.equals（Intent.ACTION_BOOT_COMPLETED））{
        Log.d（接收器，动作：启动）;
    }
    如果（action1.equals（android.intent.action.PACKAGE_REPLACED））{
        Log.d（接收器，动作是：包）;
    }
}
 

当我运行的应用程序的接收器捕获 android.intent.action.PACKAGE_REPLACED 但是当我重新启动手机，接收器不赶 BOOT_COMPLETED 。
然而，当我在 .OtherReceiver 在注释中的 Mainfest 的文件，它可以抓住它！
这里是这个类的code：

  OtherReceiver延伸的BroadcastReceiver {public类

@覆盖
公共无效的onReceive（背景为arg0，意图ARG1）{

    串动= arg1.getAction（）;

    如果（action.equals（Intent.ACTION_BOOT_COMPLETED））{
        Log.d（新的接收器，动作：启动）;
    }

}
}
 

正好相同的另一个。所以我的问题是，为什么我需要定义的 BOOT_COMPLETED 操作单独的接收？
修改我也试图通过亚洲开发银行根据这个，并且没有任何许可，我可以用的鸭preceiver抓住它的类：

  AM广播-a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n com.blubuk / .AP preciever
 

解决方案

首先，删除安卓权限=android.permission.RECEIVE_BOOT_COMPLETED从＆LT;接收器GT; 元素

二，你的＆lt;数据＆GT; 部分的＆LT;意向滤光器＆gt; 正在申请的所有＆lt;作用＆GT;内元素 ＆LT;意向滤光器＆gt; ，你不想。没有乌里在 ACTION_BOOT_COMPLETED 。

不过，而不是创建一个单独的＆LT;接收器＆GT; 元素，你可以只创建一个单独的＆LT;意向滤光器＆gt; 元素的原＆LT;接收器＆GT; 元素。将你的＆lt;作用机器人：名称=android.intent.action.BOOT_COMPLETED/＆GT; 新＆LT;意向滤光器＆gt; （也许这 com.myApp.wifitimer 一个了），使他们不受＆lt;数据＆GT; 你的第一个＆LT;意向滤光器＆gt;

I have a receiver class listening on several actions but it can not catch the android.intent.action.BOOT_COMPLETED action. What I am doing wrong? here is my manifest file:

<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <!--<receiver android:name=".OtherReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
    </receiver>-->
    <receiver android:name="com.myApp.AppReceiver" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
             <action android:name="android.intent.action.PACKAGE_ADDED"/>
             <action android:name="com.myApp.wifitimer"/>
            <action android:name="android.intent.action.PACKAGE_REPLACED" />
            <data android:scheme="package" android:path="com.myApp" />
    </intent-filter>
    </receiver>

as it can be seen I added the permission again inside the receiver and the name of the receiver gets the full name of the class as this answer suggests.
here is the broadcast receiver class:

@Override
public void onReceive(Context arg0, Intent arg1) {

    String action1 = arg1.getAction();

    if(action1.equals(Intent.ACTION_BOOT_COMPLETED)) {
        Log.d("receiver","action is: boot");
    }
    if(action1.equals("android.intent.action.PACKAGE_REPLACED")) {
        Log.d("receiver","action is: package");
    }
}

When I run the app the receiver catches the android.intent.action.PACKAGE_REPLACED but when I restart the phone the receiver does not catch the BOOT_COMPLETED.
However when I comment in the .OtherReceiver in the Mainfest file it can catch it!
here is the code of this class:

public class OtherReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context arg0, Intent arg1) {

    String action = arg1.getAction();

    if(action.equals(Intent.ACTION_BOOT_COMPLETED)) {
        Log.d("new receiver","action is: boot");
    }

}   
}

just the same as the other one. So my question is why I need define a separate receiver for the BOOT_COMPLETED action?
Edit: I also tried to send the action via adb according to this, and without any permission I could catch it with the AppReceiver class:

am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n com.blubuk/.AppReciever

解决方案

First, remove android:permission="android.permission.RECEIVE_BOOT_COMPLETED" from your <receiver> element.

Second, your <data> portion of your <intent-filter> is applying to all <action> elements within that <intent-filter>, which you do not want. There is no Uri on ACTION_BOOT_COMPLETED.

However, rather than creating a separate <receiver> element, you could just create a separate <intent-filter> element on your original <receiver> element. Move your <action android:name="android.intent.action.BOOT_COMPLETED" /> to the new <intent-filter> (and perhaps that com.myApp.wifitimer one too), so that they are unaffected by the <data> of your first <intent-filter>.
