# 解决办法 #

看起来是因为多个 jar 包里包含了同样的文件（NOTICE.txt），导致打包时因为担心相互覆盖问题而提示出错。 尝试下在 app 下的 build.gradle 中的 android 部分增加一段配置，如下面这段代码所示：

packagingOptions { exclude 'META-INF/LICENSE' exclude 'META-INF/NOTICE' }

*  没修改前的build.gradle文件

apply plugin: 'com.android.application'
    
    
    android {
        compileSdkVersion 22
        buildToolsVersion "22.0.1"
    
        defaultConfig {
            applicationId "com.oyp.csdn"
            minSdkVersion 16
            targetSdkVersion 23
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }
    
    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])

*  修改后的build.gradle文件

apply plugin: 'com.android.application'
    
    
    android {
        compileSdkVersion 22
        buildToolsVersion "22.0.1"
    
        packagingOptions {
            exclude 'META-INF/LICENSE'
            exclude 'META-INF/NOTICE'
        }
    
        defaultConfig {
            applicationId "com.oyp.csdn"
            minSdkVersion 16
            targetSdkVersion 23
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }
    
    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
    }
