Google material design library错误程序类型已经存在:android.support.v4.app.INotificationSideChannel$Stub$Proxy

java

每当我implemntation 'com.google.android.material:material:1.0.0-alpha1'尝试构建项目时添加时,Android Studio都会说:

程序类型已存在:android.support.v4.app.INotificationSideChannel $ Stub $ Proxy消息{种类=错误,文本=程序已存在:android.support.v4.app.INotificationSideChannel $ Stub $ Proxy,来源= [未知来源文件],工具名称= 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,但我没有发现与此错误有关的任何一种。谢谢

我也整天都在努力解决这个问题。最终,我成功地编译并运行了该项目。

首先,摆脱这一点:

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,然后进行编译。

如果不起作用,请清理项目,然后重新生成。

PS:我无法使targetSdkVersion’p’正常工作。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。
