Android 统计apk中方法的数量

大家都知道Android有65535方法数的问题，那我们有什么办法能查看我们App的这个值已经有多少了呢？

这里利用一个jar来查看点击下载工具

如何使用？

把下载下来的jar放到一个目录，比如我放在桌面上，使用以下命令：

# cd Desktop//在执行以下命令# java -jar C:\Users\uuxuh\Desktop\dex-method-counts.jar C:\Users\uuxuh\Desktop\SunmiWelcome_v2.1.9_uat.apk

接着回车执行，输出的信息如下：

可以清楚的看到我们的总方法数为：Read in 19542 method IDs.

具体在某一个包的使用情况也能查看清楚~
