ビルドエラーの対応

カスタム proguard に原因となっているクラスを保持するようにルールを記載した。

Path: app/proguard-rules.pro

# 通常ビルド時に発生した以下のエラー対応
# Caused by: java.lang.ClassNotFoundException: Didn't find class "jp.co.yumemi.android.code_check.item" on path: DexPathList[[zip file "/data/app/jp.co.yumemi.android.codecheck.release-jmN5-D-aVQFnwrBlTGNlUg==/base.apk"],nativeLibraryDirectories=[/data/app/jp.co.yumemi.android.codecheck.release-jmN5-D-aVQFnwrBlTGNlUg==/lib/arm64, /system/lib64, /product/lib64]]
