Answer 1

这个问题是重复的。要解决它，您必须添加

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

build.gradle中的

Answer 2

我遇到了同样的问题，我采用了上面提到的逻辑，即。加入

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

在build.gradle中

... 但它对我没有用，我添加了以下最终有效的代码...... 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'
       }

Answer 3

我也遇到过同样的问题。有些文件有＆＃34; .txt＆＃34;有些人没有。如果您一次添加一个exclude并运行您的应用，您将在＆＃34; Messages Gradle Build＆＃34;窗口显示项目中exclude所需的所有文件。我需要的就是这段代码，它解决了我的问题。

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

Answer 4

我遇到了同样的问题。我添加了这段代码：

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"

        // Enabling multidex support.
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
        packagingOptions {
            exclude 'META-INF/LICENSE.txt'
            exclude 'META-INF/LICENSE'
            exclude 'META-INF/LICENSE-FIREBASE.txt'
            exclude 'META-INF/NOTICE'
        }

}

在我的build.gradle模块：app中进入android {}

部分

最后，我在build.gradle上的adroid部分。模块应用程序是：
