質問

今日、私は"ChatSDK"をインストールしようとし、いくつかの問題がありました。今、私は私のアプリを開始したい場合は、それが常にクラッシュしています。私はこの問題を発見しました。

2019年1月以降もこの問題を抱えている人のために、もしあなたがandroidxまたは新しいマテリアルライブラリを使用している場合、この問題はGoogleがandroidxを使用してライブラリの命名形式を変更したために発生しています。 https://developer.android.com/jetpack/androidx/migrate/artifact-mappings で、あなたのライブラリを検索して、Googleがandroidxになった今、新しい名前が何であるかを確認することができます。

あなたの場合、あなたのライブラリ " android.support.design.widget.FloatingActionButton xml ファイルで、次のように呼び出されます。 com.google.android.material.floatingactionbutton.FloatingActionButton
