项目场景：

Error: A JNI error has occurred, please check your installation and try again

问题描述：

首先确保java-version 和 javac - version版本是一致的，如果不一致查找其他大佬的文章可以解决；

确保版本一致后还出现下列问题

Exception in thread "main" java.lang.UnsupportedClassVersionError: Main has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

	at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:601)

原因分析：

没有全编译代码

解决方案：

第一步， ----->全编代码

然后执行下列操作生成导入到Android Studio所需的配置文件,

1. source build/envsetup.sh

2. mmm development/tools/idegen/

3. development/tools/idegen/idegen.sh
