From 232,865 reviews, clients rate our iPhone Developers 4.9 out of 5 stars.My Android app used to pair and print flawlessly through a small Bluetooth receipt printer. Since updating targetSdkVersion to 31 (Android 12+), the pairing still shows as bonded in the system settings, yet every print attempt silently fails—no stack-trace, no toast, nothing. So far I have only updated the app’s existing permissions in the manifest, but I have not added the new Android 12 runtime permissions for Bluetooth nor touched any exported activity/service flags. I need someone who knows exactly which Bluetooth‐related declarations (BLUETOOTH_CONNECT, SCAN, ADVERTISE) and potential foreground-service or runtime request code must be added and how to call them from Xamarin. Please review the current manifest, adjust or add all required permissions, implement the run...
I need immediate help updating my Flutter app’s interface. I have complete design files ready to share, and they cover three core screens—Home, Profile, and Settings.

Once finished, the app should build and run without warnings on both Android and iOS simulators. If you can jump on this right away and deliver polished results, let’s get started—I’...

A lightweight admin panel for basic user management and message moderation should accompany the build.

I need a full-featured mobile application that recreates the entertainment experience of “TPL” on both Android and iPhone. The core focus is entertainment, but I also want a built-in commerce layer so users can explore content-related products, purchase them seamlessly, and leave feedback inside the same app. Design & feel The interface should be classic and elegant—clean typography, subtle color accents, and smooth, timeless animations that won’t date quickly.

Functional scope Please architect native or high-performance cross-platform code (Swift/SwiftUI, Kotlin/Jetpack Compose, or Flutter/React Native if you can guarantee near-native fluidity) and provide these key modules: • Pro...
My Flutter app is still in the development stage and, so far, has only been tested on Android devices. I now need to take it all the way through an iOS release.

I’m building a dedicated project-management mobile app that runs natively on both iOS and Android.
