调试服务 [英] Debugging a service

问题描述

我已经写了远程接口的服务，并在我的电脑的Eclipse的AVD安装了它。我有一个客户端的测试工具这将启动，并调用该服务的方法。最初，我有一个控制类和活动，我现在已经删除安装服务，使清单的服务如下：

I have written a service with a remote interface and installed it on my PC's Eclipse AVD. I have a client test harness which starts and invokes methods in the service. Initially I had the service installed by a control class and activity, which I have now removed, so that the manifest for the service looks like:

<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myname.gridservice"
android:versionCode="1"
android:versionName="1.0">
<application
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:debuggable="true">
    <service
        android:enabled="true"
        android:debuggable="true"
        android:name="OverlayService">
        <intent-filter>
            <action android:name="com.myname.OverlayService.SERVICE"/>
            <action android:name="com.myname.gridservice.IRemoteInterface" />
        </intent-filter>
    </service>
 </application>  
</manifest>   

所以没有活动的标记。

so there's no activity tag.

当我启动它在Eclipse中调试图标，控制台告诉我这是在安装APK（它是），但它不会显示为一个调试线程断点不触发，尽管该服务的行为是确定只要客户看到它。如果我换行的服务标签，其中有一个关联类的活动标签，并启动了，那么我就可以调试它

When I launch it from the debug icon in Eclipse, the console tells me it's installing the apk (which it is), but it does not appear as a debug thread and breakpoints aren't triggered, although the service's behaviour is OK as far as the client sees it. If I wrap the service tag in an activity tag which has an associated class and launch that, then I can debug it

是否有可能不封装在一个活动调试服务？

Is it possible to debug the service without wrapping it in an activity?

推荐答案

这是我做的四个步骤：

第一：在你的服务的第一个有趣的方法（我用的创建）：

First: In the first interesting method of your service (I used on create):

/* (non-Javadoc)    
 * @see android.app.Service#onCreate()
 */
@Override
public void onCreate() {
super.onCreate();
//whatever else you have to to here...
android.os.Debug.waitForDebugger();  // this line is key
}

第二：watiForDebuggerCommand后设置断点

Second: set break points after the watiForDebuggerCommand.

第三：通过在Eclipse中调试按钮启动应用程序。 （你或许应该已删除从清单中的主要活动推出到现在）

Third: Launch app via debug button in Eclipse. (You should probably have removed the main launch activity from the manifest by now)

最后：启动亚行和运行命令启动服务：

Last: Launch adb and run the command to start a service:

• CD $ PLATFORM_TOOLS
• 亚行外壳
• 上午startservice -n com.google.android.apps.gtalkservice/com.google.android.gtalkservice.service.GTalkService

• cd $PLATFORM_TOOLS
• adb shell
• am startservice -n com.google.android.apps.gtalkservice/com.google.android.gtalkservice.service.GTalkService
