Android UI Demo for Mobile-Service APK

Android Device Service Demo APK – Xiaomi, Vivo & Oppo

Description

I am looking for an experienced Android developer to create a simple demo/testing APK for a mobile-device software-support business.

The application will be used as a UI/workflow demonstration only. It must not perform real FRP bypass, security-lock removal, IMEI modification, or unauthorized device access.

Main Requirements

The APK should have a professional tool-style interface with:

* Xiaomi
* Vivo
* Oppo
* Device/service selection
* Device model field
* Service selection
* Order/request button
* Processing animation
* Demo result/status
* Success/failure status
* Order/reference ID
* Simple activity/history screen
* About/support section

Demo Workflow

Example:

Brand: Xiaomi
Model: Redmi Note 13
Service: FRP Reset – Demo

User clicks:

START DEMO

The application shows:

Processing request…

Then:

Demo operation completed successfully.

This is only a simulated result. No actual device security mechanism should be modified.

Requirements

* Android APK
* Modern professional UI
* Fast and lightweight
* Android phone compatible
* No unnecessary permissions
* Source code required
* Easy to change branding/name later
* API-ready architecture so a real legitimate service backend could potentially be connected in the future
* Original implementation

Freelancer Must Provide

* APK
* Complete source code
* Build instructions
* UI assets
* Installation instructions
* Bug fixing after delivery

Please provide your fixed price, development time, Android technology (Kotlin/Java/Flutter/etc.), and examples of similar apps you have built.
