我在build.gradle中添加了以下行:
implementation 'com.journeyapps:zxing-android-embedded:3.5.0'
,然后在尝试构建项目时收到此错误:
Error: Program type already present: android.support.v4.os.ResultReceiver$MyResultReceiver
任何人都可以解释该错误的含义
这是我当前的整个构建过程:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.chaimovy.myapplication"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
configurations.all {exclude group: 'android.support.v4.app', module: 'INotificationSideChannel'}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'
implementation 'com.android.support:multidex:1.0.3'
implementation 'org.web3j:core:3.3.1-android'
implementation 'com.google.android.material:material:1.0.0-alpha1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.journeyapps:zxing-android-embedded:3.5.0'
}
还有谁能建议一种通过添加新依赖项来解决它的方法?
答案 0 :(得分:0)
该库具有以下传递依赖项:
com.android.support:support-v4:25.3.1
您的某些其他应用程序依赖项与传递依赖项冲突:
com.android.support:support-v4:25.1.0
如果您不想使用zxing-android-embedded随附的传递依赖项,可以将其排除:
implementation('com.journeyapps:zxing-android-embedded:3.5.0') {
exclude group: 'com.android.support', module: 'support-v4'
}
您还可以探索解决冲突的策略:
android {
configurations.all {
resolutionStrategy.force 'com.android.support:support-v4:25.1.0'
}
}
您可以使用以下gradle命令查看所有传递依赖项:
./gradlew -q dependencies app:dependencies
