AndroidStudio升级gradle插件版本到2.3.1异常

AndroidStudio升级gradle插件版本到2.3.1之后不能运行了，提示MultiDex找不到，由此引发了很多问题。

开始升级

插件版本升级到2.3.1，配置project / build.gradle

classpath "com.android.tools.build:gradle:2.3.1"

gradle版本升级到3.3，配置project / gradle / gradle-wrapper.properties

分包引起的问题

配置分包

defaultConfig {        multiDexEnabled true    }依赖添加compile 'com.android.support:multidex:1.0.1'

小米的问题

一切都ok之后出现了新的问题，Failed to establish session
然后无法安装应用，在github上面找到了回答，瞻仰一下。

最后总结就是要把开发者模式的MIUI优化选项给关闭掉，不然安装不了。

之前还有一个开启允许Usb安装的选项，不打开的话也无法安装应用，总之小米手机特别一点。

Works !for those who suffer from this:enable developer mode - In your phone, go to Settings, About phone and click on MIUI version 7 times. You’ll see a pop up which says you are a developer now.  Go back to Settings, Additional settings, Developer options and enable USB Debugging.Connect your phone to your PC/Mac and on the phone authorize your computergo back to Developer options, scroll down to find Turn on MIUI optimization and disable it. Your phone will be rebootedTry it now :)
