FAQ
Why do you use Jetpack Compose instead of XML Layouts?
Jetpack Compose is Google’s modern, recommended toolkit for building native UI. It completely eliminates bulky XML boilerplate, runs efficiently via compiler-level optimizations, and leverages direct GPU hardware acceleration for ultra-smooth rendering.
Will the app work completely offline?
Yes. If you select the Standard or Premium package, I implement localized storage using Room DB or SQLDelight. Data caches smoothly on the device, allowing users to browse, read, and interact with the app entirely offline.
Do you handle network calls securely?
Absolutely. I use Ktor-Client or Retrofit combined with modern structured concurrency (Kotlin Coroutines & Flow) to handle network calls safely on background threads, ensuring the UI never freezes or hitches during active data transfers.
How do you guarantee the app doesn't lag?
I bypass standard development pitfalls by implementing Strong Skipping Mode, avoiding high-level container opacity hacks, utilizing deferred state reads, and shipping code optimized via R8 and Baseline Profiles for faster application startup.
Can you publish the app to my Google Play Console?
Yes, app submission is included out-of-the-box in the Premium tier and can be easily added as an extra service for the Basic and Standard tiers. I will generate the optimized Android App Bundle (.aab) and guide you through the process.
