我已经尝试了所有方法，但仍然无法正常工作.

这是错误.

解决方案

如果在 build.gradle 的依赖项中多次包含相同的库/目录，就会发生错误.好的，假设您有一个如下所示的 App 结构:

所以你有主应用程序"，然后你有一堆子应用程序/模块/库.这些库是:1) gene_test_library, 2) genes_nine_old_androids_library, &3) swipe_list_view_library.

我的名字是 Gene，这就是为什么会有所有这些基因"库的原因.

在 app" 的 build.gradle 中，我有:

依赖项{编译文件树(包括:['*.jar']，目录:'libs')编译'com.android.support:appcompat-v7:21.0.0'编译项目(':libraries:gene_test_library')//编译项目(':libraries:genes_nine_old_androids_library')编译项目(':libraries:swipe_list_view_library')}

在 gene_test_library 的 build.gradle 里面，我什么都没有:

依赖项{}

在 gene_nine_old_androids_library 的 build.gradle 中，我有:

依赖项{编译文件树(目录:'libs'，包括:['*.jar'])编译'com.android.support:appcompat-v7:21.0.0'}

在 build.gradle 中用于 swipe_list_view_library，我有:

依赖项{编译'com.nineoldandroids:library:2.4.0+'编译文件树(目录:'libs'，包括:['*.jar'])编译'com.android.support:appcompat-v7:21.0.0'}

这行代码 compile fileTree(dir: 'libs', include: ['*.jar']) 只是意味着嘿，看看这个模块内的 'libs' 文件夹中是否有任何jar 文件.我在任何模块的 libs 文件夹中都没有任何内容，因此您可以忽略该行代码.

假设我取消注释 //compile project(':libraries:genes_nine_old_androids_library')在 app" 模块的 build.gradle 中.然后我会得到 UNEXPECTED TOP-LEVEL EXCEPTION:" 错误.这是为什么?

好吧，在app"的build.gradle中编写//compile project(':libraries:genes_nine_old_androids_library')，是与获取 genes_nine_old_androids_library" 模块的构建依赖项并将其放在那里相同.因此取消注释 //compile project(':libraries:genes_nine_old_androids_library') 语句，app"模块的 build.gradle 变为:

依赖项{编译文件树(包括:['*.jar']，目录:'libs')编译'com.android.support:appcompat-v7:21.0.0'编译项目(':libraries:gene_test_library')***编译文件树(目录:'libs'，包括:['*.jar'])******编译'com.android.support:appcompat-v7:21.0.0'***编译项目(':libraries:swipe_list_view_library')}

注意现在 compile 'com.android.support:appcompat-v7:21.0.0' 显示 2 倍.这就是错误的来源.

I have a trouble trying use a Google Play Services on my Android App using Android Studio.

I've tried everything and still doesn't work.

This is the error.

Thanks. Best Regards.

解决方案

The error occurs when you have the same library/directory included more than once in your build.gradle's dependencies. Ok, let’s say you have an App structure that looks like this:

So you have the main "app" and then you have a bunch of sub-apps/modules/libraries. The libraries are: 1) gene_test_library, 2) genes_nine_old_androids_library, & 3) swipe_list_view_library.

My name is Gene, so that’s why there are all these "gene" libraries.

Inside the build.gradle for "app", I have:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:21.0.0'

    compile project(':libraries:gene_test_library')
    //compile project(':libraries:genes_nine_old_androids_library')
    compile project(':libraries:swipe_list_view_library')
}

Inside the build.gradle for gene_test_library, I have nothing:

dependencies {
}

Inside build.gradle for gene_nine_old_androids_library, I have:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.0'
}

Inside build.gradle for swipe_list_view_library, I have:

dependencies {
    compile 'com.nineoldandroids:library:2.4.0+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.0'
}

This line of code compile fileTree(dir: 'libs', include: ['*.jar']) just means "hey, look inside the ‘libs’ folder inside this module for any jar files. I do not have anything in the libs folder of any of the modules so you can ignore that line of code.

So let’s say I uncomment out //compile project(':libraries:genes_nine_old_androids_library') In the build.gradle for the "app" module. Then I would get the "UNEXPECTED TOP-LEVEL EXCEPTION:" error. Why is that?

Well, writing //compile project(':libraries:genes_nine_old_androids_library') inside the build.gradle for "app", is the same as taking the build dependencies of "genes_nine_old_androids_library" module and putting it there. So uncommenting the //compile project(':libraries:genes_nine_old_androids_library') statement, the build.gradle for "app" module becomes: 

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:21.0.0'

    compile project(':libraries:gene_test_library')
    ***compile fileTree(dir: 'libs', include: ['*.jar'])***
    ***compile 'com.android.support:appcompat-v7:21.0.0'***
    compile project(':libraries:swipe_list_view_library')
}

Notice how now compile 'com.android.support:appcompat-v7:21.0.0' shows up 2x. That’s where the error is coming from.
