本文讨论了在使用Android Studio进行应用开发时遇到的错误：在打包APK过程中发现META-INF/LICENSE.txt文件被复制多次。通过在build.gradle文件中添加排除规则，可以避免这一问题并顺利完成应用打包。

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'
}
