Android Studio 第三方jar包报错(Error: duplicate files during packaging of APK)

Error:duplicate files during packaging of APK I:\work\android\androidstudio\workplace\GuangXiRefuelAPP\app\build\outputs\apk\app-debug-unaligned.apk
    Path in archive: META-INF/LICENSE.txt
    Origin 1: I:\work\android\androidstudio\workplace\********\app\libs\fastjson-1.2.5.jar
    Origin 2: I:\work\android\androidstudio\workplace\********\app\libs\httpmime-4.1.2.jar
You can ignore those files in your build.gradle:
    android {
      packagingOptions {
        exclude 'META-INF/LICENSE.txt'
      }
    }
Error:Execution failed for task ':app:packageDebug'.
> Duplicate files copied in APK META-INF/LICENSE.txt
    File 1: I:\work\android\androidstudio\workplace\********\app\libs\fastjson-1.2.5.jar

    File 2: I:\work\android\androidstudio\workplace\********\app\libs\httpmime-4.1.2.jar

解决方法：

      在app文件下build.gradle中的android节点下加入

     

packagingOptions {    exclude 'META-INF/LICENSE.txt'    exclude 'META-INF/NOTICE.txt'}
