OSGI包采用Android API正显示出＆QUOT;了java.lang.RuntimeException：存根！在android.util.Log.d＆QUOT; [英] OSGI Bundle using Android API is showing "java.lang.RuntimeException: Stub! at android.util.Log.d"

问题描述

在我的Eclipse插件的项目，我想使用Android API。我只是表现出对LogCat中的消息。

在除了添加的android.jar 我的类路径，我prepared 的android.jar 作为通过follwing 这链接捆绑。所以，我做了以下内容：

1-写入其中包含以下的MANIFEST.txt：

 清单-版本：1.0
创建-人：我自己
束ManifestVersion：2
束名称：Android
束描述：OSGi包包装机器人
束版本：4.4.0
束CLASSPATH中，的android.jar
束SymbolicName：机器人
出口包装：android.util
 

2 - 创建通过运行以下命令包jar文件：

 罐子CVFM Android的bundle.jar manifest.txt的android.jar
 

3现在，我有包 Android的bundle.jar ，我通过文件＆GT在Eclipse中打开它;新 - ＆GT;项目...-＆GT;插件开发 - ＆GT; 插件从现有JAR档案

接下来，我创建将采用Android API包。下面是其中有一个日志消息Activator类：

 包osgi_android_bundle;进口org.osgi.framework.BundleActivator;
进口org.osgi.framework.BundleContext;
进口android.util.Log;公共类激活实现BundleActivator的{    私有静态的BundleContext上下文    静态的BundleContext的getContext（）{
        返回语境;
    }    / *
     *（非Javadoc中）
     * @see org.osgi.framework.BundleActivator＃启动（org.osgi.framework.BundleContext）
     * /
    公共无效启动（BundleContext的的BundleContext）抛出异常{
        Activator.context =的BundleContext;
        的System.out.println（世界您好我是OSGI_Android_Bundle！）;        Log.d（扎伊德日志，世界您好我是OSGI_Android_Bundle！）;
    }    / *
     *（非Javadoc中）
     * @see org.osgi.framework.BundleActivator＃停止（org.osgi.framework.BundleContext）
     * /
    公共无效停止（BundleContext的的BundleContext）抛出异常{
        Activator.context = NULL;
        的System.out.println（再见，世界，我的OSGI_Android_Bundle！）;        Log.d（扎伊德日志，再见，世界，我的OSGI_Android_Bundle！）;
    }}
 

也是我的MANIFEST.MF为其采用了Android API包：

 清单-版本：1.0
束ManifestVersion：2
束名称：OSGI_Android_Bundle
束SymbolicName：OSGI_Android_Bundle
束版本：1.0.0.qualifier
束激活：osgi_android_bundle.Activator
进口包装：org.osgi.framework;版本=1.3.0，android.util
束RequiredExecutionEnvironment：JavaSE的-1.6
 

当我运行这个包，我得到一个打印的日志。

解决方案

此副本 android.util.Log 似乎是说，是它只是一个存根，而不是一个真正的实现。可能有人纯粹创建用于编译反对，预计不会在运行时被使用。

更新：
下面的计算器问题似乎证实了我的猜测：<一href=\"http://stackoverflow.com/questions/8982631/error-java-lang-runtimeexception-stub-in-android-with-fitnesse-testing\">Error了java.lang.RuntimeException：存根！在Android中使用FitNesse的测试

您实际上是一个Android设备或模拟器上运行？看来你可以在标准JVM上运行。

In my eclipse plugin project, I am trying to use the Android API. I am only showing a message on the LogCat.

In addition to adding Android.jar to my class path, I prepared Android.jar as a bundle by follwing this link. So I did the following:

1- Writing the MANIFEST.txt which contains the following:

Manifest-Version: 1.0
Created-By: myself
Bundle-ManifestVersion: 2
Bundle-Name: android
Bundle-Description: Package android in an OSGi bundle
Bundle-Version: 4.4.0
Bundle-ClassPath: .,android.jar
Bundle-SymbolicName: android
Export-Package: android.util

2- Creating the bundle jar file by running the following command:

jar cvfm android-bundle.jar manifest.txt android.jar 

3- Now that I have the bundle android-bundle.jar, I open it in eclipse by File-> New -> Project...-> Plug-in Development -> "Plug-in from Existing JAR Archives"

Next, I create the bundle that will use the android API. Below is the Activator class which has a Log message:

package osgi_android_bundle;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;


import android.util.Log;

public class Activator implements BundleActivator {

    private static BundleContext context;

    static BundleContext getContext() {
        return context;
    }

    /*
     * (non-Javadoc)
     * @see org.osgi.framework.BundleActivator#start(org.osgi.framework.BundleContext)
     */
    public void start(BundleContext bundleContext) throws Exception {
        Activator.context = bundleContext;


        System.out.println("Hello World. I am the OSGI_Android_Bundle!");

        Log.d("Zaid Log", "Hello World. I am the OSGI_Android_Bundle!!");
    }

    /*
     * (non-Javadoc)
     * @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.BundleContext)
     */
    public void stop(BundleContext bundleContext) throws Exception {
        Activator.context = null;


        System.out.println("Goodbye World. I am the OSGI_Android_Bundle!");

        Log.d("Zaid Log", "Goodbye World. I am the OSGI_Android_Bundle!!");
    }

}

And also my MANIFEST.MF for the bundle which uses the Android API:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: OSGI_Android_Bundle
Bundle-SymbolicName: OSGI_Android_Bundle
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: osgi_android_bundle.Activator
Import-Package: org.osgi.framework;version="1.3.0", android.util
Bundle-RequiredExecutionEnvironment: JavaSE-1.6

When I run this bundle, I get these errors at the line that prints the message on the Log.

解决方案

This copy of android.util.Log appears to be saying that's it's only a stub, rather than a real implementation. Probably it was created purely for compiling against, and is not expected to be used at runtime.

UPDATE: The following stackoverflow question appears to confirm my guess: Error java.lang.RuntimeException: Stub! in Android with Fitnesse testing

Are you actually running on an Android device or emulator?? It seems you may be running on the standard JVM.

这篇关于OSGI包采用Android API正显示出＆QUOT;了java.lang.RuntimeException：存根！在android.util.Log.d＆QUOT;的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
