错误:程序类型已存在:android.support.v4.app

Question

我正在安卓工作室开发一个应用程序，过去10分钟我运行了它，它很有效，但现在我得到了这个。我在上出错了

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

你能告诉我应该修改什么吗？

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"
}
