题

我有一个Android应用程序，它使用actionBarsherlock和ViewPagertabs。我使用Eclipse来编写和构建它，直到我尝试用蚂蚁构建它，它就很好。这是我所做的：

转到ActionBarsherlock文件夹，运行“Android更新 lib-project --path。”
转到ViewPagertabs文件夹，运行“Android Update lib-project --path。”太
转到app文件夹，运行“android更新项目 - path。”

运行“和debug”下的app文件夹，我收到以下错误：
：
[javac] C:\Android\TestApp\src\com\test\App\TestActivity.java:46: cannot find symbol [javac] symbol : method getSupportActionBar() [javac] location: class com.test.App.TestActivity [javac] final ActionBar ab = getSupportActionBar(); [javac] ^
.
所以问题没有。 1：我在app的project.properties中有正确的库引用，而ActionBarsherlock＆ViewPagertabs可以成功构建，为什么我仍然会得到这些错误？
此问题有一个解决方法 - 将库的Bin文件夹下的所有类jar复制到应用程序的libs文件夹中，并再次运行“ant debug”。但我需要在App的Libs文件夹下删除这些.jar文件。可以编译应用程序的所有.java文件。
在此之后再次运行“ant debug”，我将得到以下错误：

我的问题第2号是：如何解决这个问题？
谢谢！

解决方案

I finally resolve it myself. I find that there's a android-support-v4.jar in ViewPagerTabs' libs folder. The solution is -- deleting this android-support-v4.jar, then make ViewPagerTabs depend on ActionBarSherlock (because ActionBarSherlock actually have one copy of Support Package).

I hope it's useful for people who wants to use ActionBarSherlock & ViewPagerTabs in one application and use Ant to built his/her application. Good luck.

其他提示

You stated its because both library have android-support-v4.jar. See @porter-liu answer for non-maven builds.

For people using maven, set your ViewPager dependancy as:

    <dependency>
        <groupId>com.viewpagerindicator</groupId>
        <artifactId>library</artifactId>
        <version>2.4.1</version>
        <type>apklib</type>
        <exclusions>
            <exclusion>
                <groupId>com.google.android</groupId>
                <artifactId>support-v4</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

The exclusion tag stops the double import fixing the issue.

When you update lib-project, you're updating the project so that it compiles as a library. There's a separate step to update your main project so that it sees the library it requires.

For each library project you're going to use, run

android update project --library ../pathToTheLibrary
