Project description:
"I’m building a privately-deployed APK that sits quietly in the background of an Android device, captures both SMS and voice activity, and then acts on it with zero user intervention.

Here’s what I need built:
• A foreground/background service that listens for incoming SMS, stores each message in an in-app inbox, and forwards it to a preset number using SmsManager and BroadcastReceiver.
• Outgoing SMS capability from inside the app.
• Call interception that triggers TelephonyManager / CallRedirectionService logic to forward voice calls (MMI or other compliant approach).
• Continuous operation: the service must restart automatically after reboot, withstand Doze, and request runtime permissions only once.

I expect Kotlin or Java code that follows best practices for foreground services, power-optimised wake locks, and notification channels. When finished, deliver the full Android Studio project plus a signed release-ready APK for my own distribution.

To help me choose quickly, please share:
1. Links or APKs of any SMS or telephony-centric apps you’ve built before.
2. A short note on whether you’ll tackle this in Kotlin or Java and why that stack suits this project.

If you’re confident with SmsManager, BroadcastReceiver, TelephonyManager, CallRedirectionService, and persistent background execution, I’d love to collaborate." (client-provided description)
