我使用Android Studio3.2。我创建了一个使用 api 版本 28 的项目。现在我需要将 api 版本更改为 23。所以我编辑 build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
defaultConfig {
applicationId "com.example.administrator.myapplication"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
externalNativeBuild {
cmake {
cppFlags ""
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
externalNativeBuild {
cmake {
path "CMakeLists.txt"
}
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'
}
我将“AppCompatActivity”更改为“Activity”
但构建失败:
Android resource linking failed
Output: error: resource android:style/TextAppearance.Material.Widget.Button.Borderless.Colored not found.
error: resource android:style/TextAppearance.Material.Widget.Button.Colored not found.
