我最近安装Eclispe Juno for Java了Android.我通常.在类名后面按下以了解相关的方法,如果我想选择其他方法而不是从此列表中选择的方法,则会在IDE中弹出以下错误.

如何告诉IDE这不是错误,并且不需要一次又一次地弹出此消息？

以下是Eclipse的错误日志

我间歇性地遇到这个问题，Android 中的 DDMS 不显示任何应用程序的名称，如下图所示

考虑到日志消息的数量，如果不为特定应用程序设置过滤器，就不可能看到相关消息，这成为一个主要问题。

我的问题

DDMS 设置需要进行哪些更改才能始终在消息中显示应用程序名称？

我正在使用IntelliJ IDea 11.1.3进行Android开发,我必须承认它是一个很棒的工具.关于如何在IDE中使用Proguard我几乎没有疑问.

我在Open Module Settings - > Facets下找到了Run Progaurd的选项,如下图所示

Run Proguard需要一个Config File的位置,默认为proguard-project.txt.接下来是一个复选框,其中显示Include system proguard file.

此复选框选项中引用了什么系统Proguard文件？

鉴于Proguard的所有配置都在Android SDK的proguard-android.txt中.proguard配置如何在IntelliJ Idea中运行？

PS任何帮助将受到高度赞赏我试图用IntelliJ了解proguard近一天,并在另一个问题中遇到未解决的问题.

Android OS中使用SQLite3的CREATE INDEXAND 之间有何区别CREATE UNIQUE INDEX？索引如何在数据库中工作？它们与表中的列有何关系？

如何在不删除的情况下用新实例替换Amazon EC2实例tomcat7,mysql并在实例上完成其他设置？

对于GCM Android文档在这里声明

数据参数中的键对值,它们在此意图中作为附加项提供,键是额外的名称.

private void handleMessage(Intent intent) {
    // server sent 2 key-value pairs, score and time
    String score = intent.getExtra("score");
    String time = intent.getExtra("time");
    // generates a system notification to display the score and time
}

但是intent.getExtra()方法不接受参数

public Bundle getExtras ()

Since: API Level 1
Retrieves a map of extended data from the intent.

Returns
the map of all extras previously added with putExtra(), or null if none have been added.

我的问题

如何从onMessage()方法中的GCM消息中检索"字符串" ？

PS …

我已经从Eclipse导入了一个Android项目到IntelliJ Idea.该项目使用Android Library Actionbar Sherlock？

我的问题

如何在IntelliJ Idea CE中的导入项目中包含Android库Actionbar Sherlock？

我正在尝试使用Proguard来混淆我的Android应用程序.此外,我正在使用IntelliJ Idea 11.1.3构建发布已签名的APK,并在Open Module Settings - > Facets - > Compiler - > Run Proguard中选择Run Proguard选项.

当我不使用Proguard时,应用程序正在编译时没有任何错误,但是对于Proguard,我收到以下错误

Error:[MyApp] Warning: org.apache.commons.collections.BeanMap: can't find referenced class java.beans.Introspector
Error:[MyApp] Warning: org.apache.commons.collections.BeanMap: can't find referenced class java.beans.BeanInfo

可能的重复：
Java：子包可见性？

这是问题Java：子包可见性？. 询问的原因是为了引起更广泛的社区的注意。

问题odp.proj 和 odp.proj.subpackage 这两个包之间有关系吗？

有人试图在这里回答它，但未能描述它。

我试图在Ubuntu 12.04中运行以下命令

$ mvn jetty:run 

并得到以下错误
