add android framework library in android studio

build.gradle

buildscript {
    repositories {
        flatDir { dirs '../FrameworkJars' }
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}
apply plugin: 'android'

// self-defined providedCompile
configurations {
    providedCompile
}

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    providedCompile files('../FrameworkJars/classes.jar')
}

// for android project
android.applicationVariants.all {
    variant -> variant.javaCompile.classpath += configurations.providedCompile
}
// for standard java project
// sourceSets.main.compileClasspath += configurations.providedCompile
// sourceSets.test.compileClasspath += configurations.providedCompile
// sourceSets.test.runtimeClasspath += configurations.providedCompile

// another solution for android project
android.libraryVariants.all { variant ->
    variant.outputs.each { output ->
        output.packageLibrary.exclude('libs/someLib.jar')
    }
}
