为什么会发生

打包的时候出现失败，因为我遇见这个问题三次了 在百度上搜的答案是让我把打包选项的 Gradle换成Internal 这无非是高校

解决之策

你的错误肯定与我不同，找原因
无非是 JDK SDK NDK 版本问题
如果你看不懂报错 就复制到翻译软件上

从图中可以看出 我的错误是因为SDk版本低 让我尝试28.0.2 索性我就升级了一下SDK
升级方法：图箭头所示选择需要的版本

如果是SDK问题就会解决

如果是JDK问题呢
将JDK版本降低至jdk 8及以下即可（这里以Java SE Development Kit 8u161为例：）
可以是jdk1.8.0_171

如果你电脑上已经安装其他版本的JDK 怎么再换JDK呢
之前一直使用的是JDK1.8版本，现在要换成JDK1.7的！看见网上有很多不知道如何切换的。所以写出来，供大家分享！

我现在电脑上安装了JDK1.7和JDK1.8。接下来就是配置环境变量了！

Path配置
%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;

JAVA_HOME配置
C:\Program Files\Java\jdk1.8.0_66

CLASSPATH配置
.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar

java命令
java -version

下面切换成JDK1.7的只需要该下环境变量就可以了

更改JDK版本方式：（举例1.7）
步骤一：
将JAVA_HOME变量中写入现在的JDK1.7路径。
C:\Program Files\Java\jdk1.7.0_80
步骤二：
在PATH变量中写入JDK1.7的jre下得bin路径，（写在最前面）
C:\Program Files\Java\jre7\bin

再cmd中输入 java -version 回车 就发现JDK已经换了

这样，我们就将JDK切换了！还不用卸载原来的JDK。如果还想改回原来的JDK，只需将JDK的配置删除就可以了！

如果你没有NDK 就下载一个NDK
