应用级别（而非顶级级别）的build.gradle文件应为：

apply plugin: 'com.android.application'

repositories {
    flatDir {
        dir 'libs'
    }
}

android {

    // Stuff ...

    sourceSets {
        main {
            jniLibs.srcDir 'libs'
        }
    }

   // Stuff ...
}

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])

    // Stuff..
}
