Android将library项目打包成jar文件

1 >>> File - new Module - Android Library  - finish

这样就创建了一个library项目。

这里比较libaray/build.gradle与application/build.gradle的不同之处，很清楚，就不多说了。

libaray/build.gradle

apply plugin: 'com.android.library'
 
android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
 
    defaultConfig {
        minSdkVersion 15
        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 'com.android.support:appcompat-v7:21.0.3'
}

application/build.gradle

apply plugin: 'com.android.application'
 
buildscript {
    repositories {
        jcenter()
    }
 
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}
 
repositories {
    jcenter()
}
 
dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':library')
}
android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
 
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }
}

找到新建的library目录下的buidle.gradle，在末尾添加:

//task to delete the old jar
task deleteOldJar(type: Delete) {
    delete 'release/AndroidPlugin.jar'
}
 
//task to export contents as jar
task exportJar(type: Copy) {
    from('build/intermediates/bundles/release/')
    into('release/')
    include('classes.jar')
    ///Rename the jar
    rename('classes.jar', 'AndroidPlugin.jar')
}
 
exportJar.dependsOn(deleteOldJar, build)

然后sync Now 或者 sync gradle message。

点击展开mylibrary，找到exportJar，双击开始打包。

最后jar包存放的路径在 reslease 文件夹
