每当我尝试构建项目时添加 implemntation 'com.google.android.material:material:1.0.0-alpha1'
时,Android Studio 都会说:
Program type already present: android.support.v4.app.INotificationSideChannel$Stub$Proxy Message{kind=ERROR, text=Program type already present: android.support.v4.app.INotificationSideChannel$Stub$Proxy, sources=[Unknown source file], tool name=Optional.of(D8)}
这是我的 gradle 脚本:
apply plugin: 'com.android.application'
android {
compileSdkVersion 'android-P'
defaultConfig {
applicationId "it.smart.bab3"
minSdkVersion 21
targetSdkVersion 'p'
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.google.android.material:material:1.0.0-alpha1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.support:design:28.0.0-alpha1'
implementation 'com.android.support:support-v4:28.0.0-alpha1'
}
我是这种类型的错误的新手,我没有发现这个错误。谢谢
最佳答案
我也整天都在为这个问题苦苦挣扎。最后,我成功编译并运行了项目。
首先,摆脱这个:
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support:design:28.0.0-alpha1'
implementation 'com.android.support:support-v4:28.0.0-alpha1'
在您的 gradle.properties 文件中添加以下内容:
android.useAndroidX = true
android.enableJetifier = false
最后,同步项目,然后编译。
如果不起作用,请清理项目,然后重新构建。
PS:我无法让 targetSdkVersion 'p' 工作。我的 build.gradle 文件最终如下:
apply plugin: 'com.android.application'
android {
compileSdkVersion 'android-P'
defaultConfig {
applicationId "com.github.alvarosct02.demo"
minSdkVersion 19
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.google.android.material:material:1.0.0-alpha1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
希望它也对你有用。
