我正在遵循一些指示。尽管遵循了这些说明(我希望我能正确地遵循它!),但是我还是遇到了错误。
错误:无法解决: :preset-test-package-all-v3.0.19-datasetpackage3.0.19:
代码:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.demo.myapplication"
minSdkVersion 15
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-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'
implementation(name: 'preset-test-package-all-v3.0.19-datasetpackage3.0.19', ext: 'aar')
implementation 'com.google.android.gms:play-services-ads:9.+'
}
repositories {
flatDir {
dirs 'libs'
}
}
我在做什么错?
