记一次DCloud和穿山甲广告的问题

发表于 | 更新于

因为项目包体要求，采用DCloud中的wap2app模块，而广告采用的是穿山甲。整个过程还算顺利。但是最后在编译release
包的时候，出现了crash

通过关键信息java.lang.VerifyError，查阅互联网的一些博客，解决方法有很多，感觉应该是一个简单的问题。我在这个项目
中的表现是

  • debug包没有问题，release包在部分机器上有问题

  • release包在android 7.1.1中crash, 但是在android 9.0中没有问题

  • debug和release包的混淆和配置都一样

  • 穿山甲提供的demo在相同的环境下，没有crash

网络中给的此类问题的解决方法:

  • clean project & delete build finder & rebuild project

  • clean project and Invalidate Caches/Restart menu

  • 修改配置

    go to “File” > “Settings” > “Build, Execution, Deployment” > “Instant Run”,
    uncheck the box “Enable Instant Run…” and click “OK” button

  • 修改proguard

  • 换电脑编译

这个问题的主要意思是类是没有错误但是版本不统一

最会检查到穿山甲中依赖gif库， 版本为1.2.6

但是DCloud 5plus+中也依赖这个gif库, 但是版本为1.2.15

差距很大。

现在这个阶段的解决方法，只能出debug包，静等他们更新依赖库
