VoicePing Walkie Talkie Android SDK

Worry no more! You can add it quickly with VoicePing Android SDK that works together with VoicePing Open Source Router.
Simple integration, customizable, and free! What are you waiting for? 🎉

VoicePing Android SDK is an Android library, provided by Smart Walkie Talkie, for enabling Push-To-Talk (PTT) functionality to your Android project. It allows you to quickly add group voice broadcast capability to your app. VoicePing Android SDK comes with a reference Android App (with UI) that demonstrates the one button Push-To-Talk interface.

Get Started

You can test our sample app here: Download VP Demo app. The sample app allows you to test the Walkie Talkie function. You will need at least two android devices to test properly.
You can input any user ID and company name. To communicate, devices should have same company name but different user ID.
