Upgrade App to Android 14 Compatibility

My application currently targets API level 31 to 33. I need it updated to target Android 14 (API level 34) or higher. The app is stable with no known issues or bugs, so the primary task will be the API level upgrade.

Ideal Skills:
- Proficient in Android app development
- Experience with API level upgrades
- Knowledge of Android 14 features and requirements

Please provide a timeline and cost estimate for this task.
