Android Studio 错误 Duplicate files copied in APK META-INF/LICENSE.txt

解决方法：编辑build.gradle  并在其中添加如下代码

android {              packagingOptions {          exclude 'META-INF/DEPENDENCIES.txt'          exclude 'META-INF/LICENSE.txt'          exclude 'META-INF/NOTICE.txt'          exclude 'META-INF/NOTICE'          exclude 'META-INF/LICENSE'          exclude 'META-INF/DEPENDENCIES'          exclude 'META-INF/notice.txt'          exclude 'META-INF/license.txt'          exclude 'META-INF/dependencies.txt'          exclude 'META-INF/LGPL2.1'      }  }
