Question

我是android studio的新手，我在研究后添加了一个库，添加了库但是经过大量工作后显示gradle sync失败。现在我厌倦了东西，所以我发布了我的build.gradle文件库模块， app模块和主项目。请帮助我，我想知道图书馆是否完美添加。

图书馆的build.gradle

apply plugin: 'com.android.application'

android {
  compileSdkVersion 17
  buildToolsVersion "19.1.0"

defaultConfig {
    minSdkVersion 5
    targetSdkVersion 17
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
  }
}

dependencies {
  compile 'com.android.support:support-v4:18.+'
  compile project (':androidHorizontalListView')
}

app moudle的build.gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.example.pc2.horizontalscroll"
    minSdkVersion 21
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}

dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile project(':androidHorizontalListView')
}

整个项目的3 .build.gradle

apply plugin:'java'

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

dependencies {
    compile project(':app')
    compile project(':androidHorizontalListView')

}

Answer 1

首先，您应该使用适当的插件设置您的库：

com.android.library

而不是

com.android.application

第二步还将在包含所有子项目的项目根目录中设置settings.gradle文件，以使引用有效：它应该包含：

include: ':app',':androidHorizontalListView'

请再试一次以编译项目。

Answer 2

有一种简单的方法可以从Android Studio左侧选择文件然后选择新模块 - ＆gt;导入现有项目 - ＆gt;浏览库的位置 - ＆gt;完成

还在应用build.gradle中添加编译项目（'：your library'），这就是全部。

Answer 3

我发现了.. 我把这条线错了编译项目（＆＃39;：androidHorizontalListView＆＃39;）在库项目的build.gradle中，删除此行后我的代码工作正常。另外根据评论和建议更改com.android.library 而不是com.android.applicatiion。
