android - 错误 : Program type already present: android. support.v4.app

Question

我正在 Android Studio 中开发一个应用程序，过去 10 分钟我运行它并且它可以工作，但现在我明白了。我在

处遇到错误

implementation 'com.android.support:appcompact-v7:28.0.0'

你能告诉我我应该修改什么吗？

 apply plugin: 'com.android.application'

    android {
        compileSdkVersion 28
        defaultConfig {
            applicationId "com.quizonwheels.quizonwheels"
            minSdkVersion 21
            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:appcompat-v7:28.0.0'
        implementation 'com.android.support:design:28.0.0'
        implementation 'com.android.support.constraint:constraint-layout:1.1.3'
        implementation 'com.android.volley:volley: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.github.ViksaaSkool:AwesomeSplash:v1.0.0'

    }

Answer 1

AwesomeSplash 库正在使用支持库的 v23。

将实现更改为:

implementation ('com.github.ViksaaSkool:AwesomeSplash:v1.0.0') {
    exclude group: "com.android.support"
}
