Migrating to the AppCompat Library
Overview
Android Studio v3.4.1 and higher will now start forcing AndroidX namespaces. See this document for migrating libraries and imports.
The AppCompat library enables the use of the ActionBar and Material Design specific implementations such as Toolbar on devices running Android 5.0 (API level 21) or higher.
Caution: The current androidx.appcompat:appcompat:1.7.x stable release requires a minSdkVersion of 21 (Android 5.0). The 1.8.0 alpha line moves the default minSdk to API 23 (Android 6.0) — see the AppCompat release notes for the canonical version table.
android {
compileSdk 36
}
dependencies {
// See https://developer.android.com/jetpack/androidx/releases/appcompat
implementation 'androidx.appcompat:appcompat:1.7.1'
}
