React Native APK Generation

I need assistance converting a complete and functional React Native project into an .apk file. I've attempted this before but ran into errors, and I'm unsure about creating a keystore file for signing the APK.

Ideal Skills and Experience:
- Expertise in React Native
- Experience generating APKs from React Native projects
- Familiarity with keystore files and APK signing
- Problem-solving skills to troubleshoot and resolve errors
