在对接很多工作室业务中有些客户需要在他们自带的有些app中加注册码或者验证码的需求。其实操作起来也很简单。很多反编译软件有自带的注入功能。例如注入弹窗。这个是需要对应的注册码来启动应用。而且是随机id。重新安装app后需要重新注册才可以继续使用，原则上可以杜绝工作室外发定制app的滥用。

加注册码效果如图

上个博文解析了下app去广告  去弹窗，

反编译apk 修改apk 去广告 去弹窗等操作中的一些常识

结合上个博文我们基本可以了解到弹窗在什么位置。根据客户的需求。编译生成一个文件用于注册码的验证方式。然后在app中反编译加入弹窗即可.

在app中我们要基本了解app相关文件的作用，这个是前提条件之一

show开头的源代码中就标示是弹窗对话框.去弹窗 加弹窗.修改app中的 AndroidManifest.xml文件.兴趣的友友可以使用反编译软件中的注入弹窗内容  然后对照原文件来参考弹窗的生成。

还有很多云注入弹窗方式。

去掉app云注入弹窗

第一种方法:dex搜索代码:invoke-virtual {v0}, Landroid/app/AlertDialog;->show()V 然后删除即可!

第二种方法:搜索代码:invoke-direct {p0}, Lcom/cloudinject/feature/App;->̗̖̙̗̖̖()V  然后删除即可!

第三种方法:搜索字符串:"无联网",找到当前方法,开头添加: return-void

第四种完美去除法:找到入口,替换入口即可,删除云注入dex和assets目录下的云注入文件,找入口可参考搜索:.super Landroid/app/Application;一般第四行就是了.可以参考以上
