如何让Android Studio识别我的库模块的jar文件？

Question

我有一个Android Studio项目，可以很好地构建和运行，但是在Android Studio编辑器中，所有依赖于jar文件的代码都显示为具有编译器错误。这是一个截图：

我的项目结构是

Project
- AndroidApp
- AndroidLibrary
  - build
  - libs
     - acra-4.5.0.jar
     - activation.jar
     - (More jar files)
  - src
     - (library source code)

这里是图书馆build.gradle：

的内容

apply plugin: 'android-library'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.1'

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 16
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile files('libs/acra-4.5.0.jar')
    compile files('libs/activation.jar')
    compile files('libs/additionnal.jar')
    compile files('libs/guava-14.0.1.jar')
    compile files('libs/mail.jar')
    compile files('libs/robotium-solo-5.0.1.jar')
}

我在idea.log中看到的唯一错误就是这个

如何让Android Studio识别我的jar文件？还有其他任何疑难解答提示吗？

Answer 1

我通过创建一个新的Java库模块并将所有第三方jar放在那里来解决这个问题。我没有在该模块中添加我自己的任何java代码。然后我使我的Android库模块依赖于该模块。我的新项目结构是

Project
- AndroidApp
- AndroidLibrary
  - build
  - src
     - (library source code)
- Java Library
  - libs
     - acra-4.5.0.jar
     - activation.jar
     - (More jar files)
