1.dexDebug ExecException finished with non-zero exit value 2 全bug日誌如下：
(Error:Execution failed for task ':app:dexDebug'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'D:\JDK8\jdk1.8.0_11\bin\java.exe'' finished with non-zero exit value 2)
需要在gradle中配置下面的代碼，原因是引用了多個libraries文件
defaultConfig {
multiDexEnabled true
}
2.Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v4/app/BackStackState$1.class
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/annotation/ArrayRes.class
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/android/volley/ServerError.class
原因：在所添加的jar包或aar包中也引用了support-V4,與工程中引用的相沖突
Ctrl+N --> 在搜索框中輸入BackStackState --> 查找到所有引用該類的類，這些類即爲引起衝突的類
去掉本工程中gradle中用於引用有衝突的包的代碼或者將衝突的代碼從jar包或aar包中移除，確保一個module中只引用了一份相同的第三方包
3.project sturcture和Project Structure 無論是按快捷鍵或者是從files中打開都不顯示
event log中報：IllegalArgumentException:Multiple entries with same key: Google Inc.:Google APIs:23=Google APIs (Google Inc.) (API 23) and Google Inc.:Google APIs:23=Google APIs (Google Inc.) (API 23)
解決辦法：先看一下系統配置的SDK的位置和Android Studio所用的路徑是否一致，如果不一致重新配置系統的SDK路徑或者是重新修改Android Studio的SDK路徑
通過SDK Manager刪除掉google API23
如果解決不了，卸載android studio -->重新安裝 ,還有問題點擊File --> Invalidate Cashes/Restart --> Invalidate and Restart,解決不了繼續通過SDK Manager刪除掉google API23

項目中有錯，無法刪除這個文件夾下面的文件。手動刪除debug文件夾或某工具粉碎即可(補充與20160916)。

應該是Library的sdk的版本與app的sdk的版本有衝突

Error:Execution failed for task ':app:compileDebugJavaWithJavac'.

需要把dependencies中的lib包下面的jar包全部取消下，再添加。

11.由於使用sdk5.0造成的以下問題，需要用sdk6.0
E:\as_workspaces\DJIgo\app\build\intermediates\res\merged\debug\values-v23\values-v23.xml

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.

包衝突了，在app及子library中仔細找是否有相同的jar包

無法刪除這個文件夾下的文件，到目錄下面就知道了。
15.
關於R文件無法引入，導致很長時間無法找到錯誤的根源。比如：如果錯誤在A類裏面發生，但是Message裏提示的是B類的R文件無法引入。
這樣你就要用排除法，就像做選擇題，要將B類的問題先註釋掉，A類裏面的問題纔會暴露出來。

關於該問題，需要注意的是。有時候雖然有個紅叉但是也能運行，可能as校驗導致該問題。另外如果代碼中沒有什麼問題時，就需要查看下AndroidManifest.xml是否有錯誤，一般情況下是這個原因導致。只要知道這個即可。

Error:Execution failed for task ':Tongyan_StructureCheck_Library:clean'.

按照上面的說明，不能刪除這個目錄，你就手動刪除下

Unable to delete directory 像這樣不能刪除文件，你就找這個這個文件夾刪除掉，如果不能刪除就粉碎掉。官網的錯誤提示還是比較傻瓜式的，他讓你幹嘛，你就幹嘛就行了。
