运行项目时出错
我想实现材料设计的芯片功能。因此，我遵循了该过程，但是在运行应用程序时出现错误。我指的是this文章和this。

以下是依赖性。

 android {
        compileSdkVersion 28
        defaultConfig {
            applicationId "com.example.materialdemo"
            minSdkVersion 18
            targetSdkVersion 28
            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:design:28.0.0-alpha1'
        implementation 'com.android.support:support-v4:28.0.0-alpha1'

        implementation 'com.google.android.material:material:1.0.0-alpha3'

        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'
    }

</LinearLayout>

获取错误信息

错误：程序类型已存在： android.support.v4.os.ResultReceiver $ MyResultReceiver

实施google Material Design库时，由于程序类型已存在而出现错误
