androidStudio中編譯出現AIDL找不到接口類

需要在build.gradle文件中添加以下配置:

sourceSets {
    main {
        manifest.srcFile 'src/main/AndroidManifest.xml'
        java.srcDirs = ['src/main/java', 'src/main/aidl']
        resources.srcDirs = ['src/main/java', 'src/main/aidl']
        aidl.srcDirs = ['src/main/aidl']
        res.srcDirs = ['src/main/res']
        assets.srcDirs = ['src/main/assets']
    }
}
