I have coded an app in android studio backend in kotlin Few things that can be problematic(but I'm unable to find any issue in them)
- Implementation("net.objecthunter:exp4j:0.4.8") used this dependency for mathemtical operations
- private lateinit var expression: Expression to use this
I've checked package names they are working fine no issue with them
Below are the logcat error that I got (screenshot have less data I've copy pasted below the whole errors) Logcat Error
