AS 升级 gradle 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

1
classpath "com.android.tools.build:gradle:2.3.1"

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

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 computer
go back to Developer options, scroll down to find Turn on MIUI optimization and disable it. Your phone will be rebooted
Try it now :)
