Android 错误:添加QR读卡器模块时,程序类型已存在
我在build.gradle中添加了以下行:Android 错误:添加QR读卡器模块时,程序类型已存在,android,android-gradle-plugin,build.gradle,zxing,Android,Android Gradle Plugin,Build.gradle,Zxing,我在build.gradle中添加了以下行: 实现'com.journeyapps:zxing安卓嵌入式:3.5.0' 然后在尝试构建项目时出现以下错误: Error: Program type already present: android.support.v4.os.ResultReceiver$MyResultReceiver 谁能解释一下那个错误的含义吗 这是我当前的整个构建梯度: apply plugin: 'com.android.application' android {
实现'com.journeyapps:zxing安卓嵌入式:3.5.0'
然后在尝试构建项目时出现以下错误:
Error: Program type already present: android.support.v4.os.ResultReceiver$MyResultReceiver
谁能解释一下那个错误的含义吗
这是我当前的整个构建梯度:

有谁能建议一种方法来解决添加了新依赖项的问题吗?该库具有可传递依赖项:
com.android.support:support-v4:25.3.1
这与您的一些其他应用程序依赖项在以下方面的可传递依赖项相冲突:
com.android.support:support-v4:25.1.0
如果您不想使用zxing android embedded附带的可传递依赖项,可以将其排除在外:
implementation('com.journeyapps:zxing-android-embedded:3.5.0') {
exclude group: 'com.android.support', module: 'support-v4'
}
您还可以探索冲突的解决策略:
android {
configurations.all {
resolutionStrategy.force 'com.android.support:support-v4:25.1.0'
}
}
您可以使用以下gradle命令查看所有可传递依赖项:
./gradlew -q dependencies app:dependencies
