网站建设业务终止合作范本,西安市沣东新城建设局网站,wordpress 伪静态 主题失效,自我介绍的网页设计作业最近需要一些比较骚的操作#xff0c;所以需要将gson编译成dex。
因为手上有jar包#xff0c;所以就拿出了android sdk准备一把入魂#xff0c;结果报错不断#xff0c;让人无奈。只好根据报错来调整编译步骤#xff0c;不得不为安卓环境更新Debug。
1、dx变d8
并不确定…最近需要一些比较骚的操作所以需要将gson编译成dex。
因为手上有jar包所以就拿出了android sdk准备一把入魂结果报错不断让人无奈。只好根据报错来调整编译步骤不得不为安卓环境更新Debug。
1、dx变d8
并不确定安卓更名的原因但找到这个只是根据名字前面有个相同的d这对于不太熟悉更新的人来说只能靠蒙。
并不确定从哪个版本开始dx.bat更新成了d8.bat。而且在使用中命令方式也发生了变化这个后面再讲。
所以原来的dx --dex --output xxx.dex xxx.jar命令不能使用了。 2、jre环境报错。
日常使用java的人我觉得大多数人还是使用1.8。 不过随着各种软件及编译环境的更新java1.8的问题慢慢出现了也出现了各种不兼容的情况。
只是到目前为止还没有更新的动力。
这次编译报错了
Error: A JNI error has occurred, please check your installation and try again
Exception in thread main java.lang.UnsupportedClassVersionError: com/android/tools/r8/D8 has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0at java.lang.ClassLoader.defineClass1(Native Method)at java.lang.ClassLoader.defineClass(Unknown Source)at java.security.SecureClassLoader.defineClass(Unknown Source)at java.net.URLClassLoader.defineClass(Unknown Source)at java.net.URLClassLoader.access$100(Unknown Source)at java.net.URLClassLoader$1.run(Unknown Source)at java.net.URLClassLoader$1.run(Unknown Source)at java.security.AccessController.doPrivileged(Native Method)at java.net.URLClassLoader.findClass(Unknown Source)at java.lang.ClassLoader.loadClass(Unknown Source)at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)at java.lang.ClassLoader.loadClass(Unknown Source)at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source) 报错就是说java1.8太老了带不动了。
所以切换java版本运行了继续报错。
3、命令换了
C:\Users\Administrator\Desktop\gsond8

最显著的变化有两个
1、不再需要 --dex 命令
2、不能直接转化成.dex文件需要zip或者jar后缀。
