This project is a part of a trio of projects:

• Remote Numpad (this project): Written in Kotlin, this is the client which runs on an Android device and sends the user's inputs to the computer.
• Remote Numpad Server: Written in Kotlin, this is the server that runs on the computer and receives the inputs from the Android device and simulates the key presses.
• Cocoa Native Server: Written in Objective-C, this is the Bluetooth server library for MacOS X. It receives the Bluetooth data and passes it on to the Remote Numpad Server.

This is an Android project written in Kotlin and compatible with Android devices down to API level 16. It is made up of 2 activities, the main NumpadActivity and the SettingsActivity.

The NumpadActivity is the activity that displays the numpad using a ConstraintLayout and sending them through an IConnectionInterface that is decided by the user preferences. So far, wifi, classic Bluetooth (RFCOMM) and the Bluetooth HID profile are supported but BLE and Wifi-Direct are intended to be implemented in the future.

The SettingsActivity is the activity which allows the user to select the interface through which to send the inputs and the location of the server.

A short tutorial on how to use Remote Numpad can be found on Youtube and the latest stable release can be obtained from the Google Play Store

The project is set up with Android Studio so it can be compiled using Gradle or imported by any Gradle-capable and Android-capable IDE (e.g.: Android Studio, IntelliJ, Eclipse) and then compiled.

This is not a main project for me so help is very appreciated. Anyone is welcome to contribute to this project (issues, requests, pull requests).
