详解android项目由Gradle2.2切换到3.0的坑
问题1、运行的时候一直报如下错误
创新互联公司网站建设由有经验的网站设计师、开发人员和项目经理组成的专业建站团队，负责网站视觉设计、用户体验优化、交互设计和前端开发等方面的工作，以确保网站外观精美、成都网站制作、网站设计易于使用并且具有良好的响应性。
Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForApiTestDebug'.
> java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex
查了很多资料，大概意识是引用重复的库或jar的问题。
然后一遍一遍的检查，发现并没有引用重复的jar包。
最后考虑是不是第三方库引用jar出现的问题，然后就一个一个排查第三方库，最后发现我们用支付用的是
compile 'com.pingxx:pingpp-alipay:2.1.9' // 使用支付宝时添加
发现这个库有些问题，竟然在里面引用两个版本的支付宝的jar包，果断的换了最新版本，检查了一个这次就引用了一个jar包。重新编译了一下项目，运行成功，问题解决了。
特别注意：引用第三方库在gralde3.0版本是更为严格，要特别注意。
问题2、
AAPT2
AAPT2 将默认启用，如果遇到离奇的问题，可以尝试禁用，只要在 gradle.properties 中加入：
android.enableAapt2=false
其他：
应用（app）目录下build.gradle（下面 implementation "com.android.support:design:25.4.0" 切换为 project的统一配置）
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'com.google.gms.google-services'
