【Android錯誤集錦】Error:Execution failed for task ':app:processMockDebugManifest'.

錯誤描述：

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

> Manifest merger failed : Attribute application@allowBackup value=(false) from AndroidManifest.xml:23:9-36

  is also present at [net.qiujuer.common:okhttp:3.0.0] AndroidManifest.xml:17:9-35 value=(true).

  Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:22:5-39:19 to override.

問題分析：

項目依賴庫和主程式的allowBackup沖突

解決方法：

<application tools:replace="android:allowBackup"  

        android:name=".MyApplication"  

        android:allowBackup="false" >

添加tools:replace屬性，替換要覆寫的标簽屬性即可。這樣庫檔案中AndroidManifest檔案标簽屬性會被主程式的标簽屬性替換掉。
