Android Studio報錯：Error:duplicate files during packaging of APK

Error:duplicate files during packaging of APK F:\android_studio_project\nizaoma\app\build\outputs\apk\app-debug-unaligned.apk

    Path in archive: META-INF/NOTICE.txt

    Origin 1: F:\android_studio_project\nizaoma\app\libs\httpmime-4.2.4.jar

    Origin 2: F:\android_studio_project\nizaoma\app\libs\fastjson.jar

You can ignore those files in your build.gradle:

    android {

      packagingOptions {

        exclude 'META-INF/NOTICE.txt'

      }

    }

 原因：

 是因爲你的項目的兩個以上的jar包包含NOTICE.txt 文件：

   

  解決辦法：

  在build.grade 中增加：

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

如果還是有報錯將

方框內的提示覆制到packagingOptions{  }中就可以解決
