本番アプリが起動直後にエラーで落ちる

[ikemura23]

100％発生する

debugビルドでは起きない releaseビルドでのみ起きる

原因はisMinifyEnabled=trueだと思うが、具体的にどこで落ちてる？

[ikemura23]

debugビルドでisMinifyEnableをtrueにして再現させたエラーログ TopStatusRepositoryImplで発生してる？

方法1 ProGuardファイルに無視する設定をかく https://firebase.google.com/docs/database/android/start?hl=ja#proguard

方法2 クラスに@Keepをつける？ https://developer.android.com/studio/write/annotations?hl=ja#adding-annotations
