NDK缺少“平台”目录 . 在尝试 Build 时

执行任务：[clean]按需配置是一项孵化功能 . NDK缺少“平台”目录 . 如果您使用的是NDK，请验证ndk.dir是否设置为有效的NDK目录 . 它目前设置为/ Users / ishandutta2007 / Library / Android / sdk / ndk-bundle . 如果未使用NDK，请从ANDROID_NDK_HOME或local.properties取消设置NDK变量以删除此警告 . 项目'：app'中的配置'compile'已弃用 . 请改用“实施” . FAILURE：构建因异常而失败 . 出了什么问题：配置项目'：app'时出现问题 . java.lang.NullPointerException（无错误消息）尝试：使用--info或--debug选项运行以获取更多日志输出 . 例外情况是：org.gradle.api.ProjectConfigurationException：配置项目'：app'时出现问题 .
