Answer 1

这个问题是重复的.要解决它,你必须添加

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

在build.gradle中

我遇到了同样的问题,我采用了上述逻辑即.加入

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

在build.gradle ...但它不适合我,我添加了以下最终工作的代码...在build.gradle中添加以下代码

       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'
       }
