Development of a simple Android application is required.

Project description

It is necessary to develop a very simple application for Android.

The application consists of only one screen and performs one function — it accepts a text command and outputs a predefined response.

No complex logic, server part, or internet connection is required.

Functionality

The main screen should have:

- a text input field (in the style of a command line or terminal);
- a "Submit" button;
- an area to display the result.

After pressing the button, the application compares the entered text with a list of predefined commands.

If the command is found — a predefined text is displayed.

For example:

- "help" → the text "List of available commands" is displayed.
- "about" → information about the application is displayed.
- "test" → "Test completed successfully" is displayed.

If an unknown command is entered — a message is displayed:

"Unknown command."

The number of commands is small (approximately 5–10). All responses are static and predefined in the application.

What is NOT required

- internet;
- server;
- API;
- database;
- registration and authorization;
- storage of user data;
- multiple screens;
- complex logic;
- animations;
- push notifications.

Design

A neat modern interface in a minimalist style is needed.

It is preferable to use a dark theme.

Without complex effects and animations.

Requirements

- The application must work on the maximum possible number of Android devices.
- Compatibility with modern and older versions of Android.
- The code should be clear and suitable for further editing.

Work results

It is necessary to provide:

- the source code of the project;
- a ready APK for installation;
- a brief instruction where the list of commands and response texts can be changed if necessary.

When responding, please indicate:

- cost;
- deadlines;
- the minimum version of Android on which the application will work.

Good day, I am interested in your work. I can take on the task. Regarding the Android version, I think we can ensure compatibility from version 5-6 and above, up to current events. I will also prepare a Word file with screenshots for you, as well as a video instruction just in case, where I will demonstrate the replacement. The work will not pose any problems for me and will be interesting. I would be happy to collaborate with you.

A single-screen Android application in terminal style is needed: command input, comparison with a list, output of a static response. I will do it in Kotlin + Jetpack Compose, dark theme through MaterialTheme.colorScheme, minSdk 21 (Android 5.0 — covers 97%+ of devices). I will put commands and responses in one Map — easy to edit without knowledge of Android. I will provide the source code, APK, and instructions for adding commands. The cost is 800 UAH, deadline 2 days.

How many commands need to be specified at the start, and is there a specific list with response texts, or should I come up with examples myself?

Hello! An excellent task for creating a clean, native, and lightweight tool. I will develop this application in **Kotlin + Jetpack Compose** — this is a modern stack from Google that ensures clear code and maximum performance without unnecessary visual clutter.
**Answers to your questions:**
* **Cost:** $100 USD.
* **Deadline:** 2–3 days.
* **Minimum Android version:** The application will work on **Android 7.0 (API 24) and above**. This will cover over 95% of all active Android devices in the world.
**How the project will be technically implemented:**
* **Interface:** Strict minimalist design in dark mode (Dark Mode) in the style of a neat terminal. Input field, button, and text output area.
* **Command logic:** The list of commands will be placed in a separate, isolated Kotlin file in the form of a simple and understandable structure (Map). You can change a command or response in 10 seconds by simply editing the text in quotes.
* **Result:** You will receive clean source code, a ready-to-install APK build, and a text video instruction (Loom/Readme) on how to change commands.
I have extensive experience in developing native applications and cross-platform solutions; you can view my portfolio here: https://mcarrow.online
I am ready to discuss the exact list of your 5–10 commands in private messages and start working immediately!
Best regards,
Sergey

Vladislav, I see that you need a simple Android application that will simulate a console and provide predefined responses to commands. This will allow for quick testing of certain scenarios or providing information in a concise format.

I will create a single screen with an input field, a button, and an output area. The application will check commands against a list and instantly display the required text or a message about an unknown command.

Do you need the application to save the history of entered commands or previous responses?
