AndroidStudio 修改aidl路径(添加AIDL文件夹)

Ubuntu 16.04 + AndroidStudio 3.5.3 + Gradle 4.1

apply plugin: 'com.android.application'
android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.app.test"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
   //关键代码:
    sourceSets { main { aidl.srcDirs = ['src/main/aidl', 'src/main/java/com/myAidlDir'] } }
}
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
}
