以前Android Studio不會自動匹配Library中的BuildTypes，3.0以后可以自動匹配了（只要app選擇了debug屁药，后面會自動選中debug于颖，release也是一樣）
Library中需要添加buildTypes跟app的一樣，比如App中有 release debug debugTest消请，那么Library中也要有這3個(gè) 栏笆。

如果你用了類似butterknife臊泰，需要做如下改動
project的build.gradle文件中刪除
classpath ‘com.neenbedankt.gradle.plugins:android-apt:1.8’
module的build.gradle文件中刪除
apply plugin: ‘a(chǎn)ndroid-apt’
//apt 'com.jakewharton:butterknife-compiler:8.4.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
因?yàn)閍pt是個(gè)人開發(fā)者開發(fā)的蛉加，后來google官方出了對應(yīng)的是annotationProcessor以后直接使用這個(gè)

gradle也提示升級到3.0.0版本，編譯之前正常的項(xiàng)目后報(bào)錯(cuò)Error:com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details

這里寫圖片描述

缸逃，查看官方文檔后了解到

這里寫圖片描述

在gradle 3.0.0中AAPT2是默認(rèn)打開的针饥，在項(xiàng)目的gradle.properties中添加android.enableAapt2=false，sync后就編譯通過了需频。
