Android Studio将本地项目添加到Gradle

我已经附上了我当前项目设置的屏幕截图，但是在从“library”项目获取代码以在“SampleApp”项目中工作时遇到了问题。My project build.gradle包含以下内容：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

include ':SampleApp'
include ':library'

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.1'

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:19.+'
    compile project(':library')
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 11
    }

    buildTypes {
        release {
            runProguard false
        }
    }
}

而my settings.gradle包含以下内容：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

include ':SampleApp'
include ':library'

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.1'

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:19.+'
    compile project(':library')
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 11
    }

    buildTypes {
        release {
            runProguard false
        }
    }
}

My SampleApp build.gradle包含以下内容：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

include ':SampleApp'
include ':library'

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.1'

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:19.+'
    compile project(':library')
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 11
    }

    buildTypes {
        release {
            runProguard false
        }
    }
}

my library build.gradle包含以下内容：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

include ':SampleApp'
include ':library'

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.1'

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:19.+'
    compile project(':library')
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 11
    }

    buildTypes {
        release {
            runProguard false
        }
    }
}

奇怪的是，如果我尝试在SampleApp项目中包含库项目中的一段代码，我可以添加相关的，使用AndroidStudio功能添加正确的导入，并且没有错误。然而，一旦我开始构建，就会出现一个错误，表明我的包不存在。我还进入了Android Studio项目属性，并添加了库作为SampleApp的依赖项。
非常感谢您的帮助

在您的库的build.gradle中，而不是：

apply plugin: 'android'

这样做：

apply plugin: 'android-library'
