广播接收器接收不到ACTION_BOOT_COMPLETED如果应用程序尚未运行？ [英] Broadcast Receiver not receiving ACTION_BOOT_COMPLETED if app hasn't been run?

问题描述

我一直在努力创造一个没有一个活动的应用程序服务，我遇到了一些问题。

我要服务，从开机运行，所以自然使用 BroadcastReciever 捉 ACTION_BOOT_COMPLETED 这是没有问题而测试。我用了一个活动来启动和停止服务来测试它正在重新启动，然后看是否启动接收机的工作，它没有，快乐的日子。

删除了测试活动，并从应用程序和使用下面的清单。

卸载然后重新安装应用程序，重新启动设备并没有什么。测试了几个时间 -a android.intent.action.BOOT_COMPLETED亚行外壳AM广播，仍然一无所获。

一些试验和错误我想通了广播接收器后从未收到 ACTION_BOOT_COMPLETED 如果应用程序从未运行。当然，没有一个发射器，它永远不会运行。

我错过了什么？我还没有见过这样的任何提及的文件中。

修改1

进行了一些测试，我AOSP版本，上面的清单是在姜饼罚款，但不能在果冻豆。一定有什么变​​化，我只能假设这是出于安全原因（可以理解）。虽然我还没有看到任何文件支持的事实。

I have been trying to create an app service that does not have an Activity and i ran into some issues.

I want the service to run from boot, so naturally used a BroadcastReciever to catch ACTION_BOOT_COMPLETED this is no problem while testing. I used an Activity to start and stop the service to test it was working then rebooted to see if the boot receiver worked, it did, happy days.

Removed the test Activity and from the application and used the below manifest.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.package"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <!-- <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
             <action android:name="android.intent.action.MAIN" />
             <category android:name="android.intent.category.LAUNCHER" />  
        </intent-filter> 
    </activity>  -->
    <receiver android:name=".BootReceiver">
        <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
    <service android:name=".SWKeepAliveService" />
</application>
</manifest>

Uninstalled then reinstalled the application, reboot the device and nothing. Tested it a few time with adb shell am broadcast -a android.intent.action.BOOT_COMPLETED, still nothing.

After some trial and error i figured out the broadcast receiver never receives the ACTION_BOOT_COMPLETED if the application has never run. Of course without a launcher, it would never run.

Have i missed something? I haven't seen any mention of this in the documentation.

EDIT 1

Ran some tests with my AOSP builds, the above manifest is fine on Gingerbread, but NOT on Jelly Bean. Something must have changed, i can only assume it's for security reasons (understandable). Though I haven't seen any documentation to support the fact.

Yes.

I haven't seen any mention of this in the documentation.

It was mentioned in the Android 3.1 release documentation, blog posts by balding guys, and a seemingly infinite number of answers here on StackOverflow.
