排除代碼問題
檢查了半天沒有找到問題在哪，又換另一台電腦，同樣的代碼和IDE（都是Android Studio 3.1.2，隻是在Ubuntu上），運作沒有任何問題，那麼問題應該并不是出在代碼上，于是想到建立一個項目試試。于是直接建立了一個新項目，沒有修改任何設定，建立了一個甚至連活動都沒有新項目
果然，剛剛建立的項目在Build時報出同樣的錯誤
查閱資料，有網友表示“如果有問題可以退回到之前的版本，打開gradle.properties，添加如下内容”
android.enableAapt2=false
對于一個習慣跟在技術更新前沿的人來說，回退版本是不可能的，這輩子都不可能的，但是添加代碼還是可以試試，于是便做出了嘗試，但還是遇到了報錯：
錯誤資訊：
The option 'android.enableAapt2' isdeprecated and should not be used anymore.
Use 'android.enableAapt2=true' to removethis warning.
It will be removed at the end of 2018..
翻譯一下就是：
選項“android.enableAapt2”已被棄用，不應再使用。
使用“android.enableAapt2=true”來删除這個警告。
它将在2018年底被移除。
很明顯，我們使用“android.enableAapt2=false”來關閉AAPT2是行不通的，這個方法已經過時了，關閉之後Android Studio告訴我們要把它打開，這樣就陷入了一個死循環，是以我們還是需要找到問題的根本原因在哪裡才能解決。
是以直接删除了剛才插入的“android.enableAapt2=false”繼續找辦法
列印報錯資訊
查閱各方資料，學到了一個可以在Android studio中列印詳細報錯資訊的方法：
在指令行中進入項目的根目錄，或者可以在Android studio的Terminal中直接操作也可以，然後敲入一個指令：
gradlew compileDebug --stacktrace
就可以輸出較詳細的資訊，然後根據指令行給出的提示，還可以在後面加上-info或者-debug的選項得到更詳細的資訊，于是這個指令可以這樣寫：
gradlew compileDebug --stacktrace -info
或者：
gradlew compileDebug --stacktrace -debug
先試第一行代碼
在Android Studio自帶的Terminal内輸入
gradlew compileDebug --stacktrace
回車之後并沒有給我們太多提示，但是在建議中有一句提到“Task'compileDebug' is ambiguous in root project”（翻譯：指令“'compileDebug”在根項目中是不明确的），回看之前的報錯，第一行提到了一個資源異常“ResourceException”
于是嘗試着把指令改成了
gradlew compileDebugSources --stacktrace -info
再看顯示出來的資訊，好像發現了點什麼

發現了中文！
敏感的察覺到，這裡可能有問題！（胡說八道，其實是請教了一位大佬）
問題根源
“有人提到目前的這種非AsciⅡ的确是AAPT2和Gradle插件的一個bug，但現在已經被修複，隻是Android Studio還未更新成這個被修複的版本。”（大佬說的，暫未查證資料來源）
解決辦法
是以現在有兩個解決辦法，
一、修改gradle的緩存目錄
這個可以通過android studio的設定中找到gradle，配置另一個非中文目錄來緩存。
File -> Settings -> Build, Execution,Deployment -> Gradle
進入這個頁面找到“Service directory path”項，将裡面的路徑換到一個非中文路徑就好了
build成功！
二、指定你的項目使用較新的gradle 插件
在build.gradle(Project)中修改Gradle版本到3.2.0-alpha11或更新版本就可以了
repositories {
google()
...
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0-alpha11'
}
}
最後還是提醒大家，開發程式不要使用中文目錄，會帶來無窮的困擾啊！！！
