ChatKit for Android

ChatKit is a library designed to simplify the development of UI for such a trivial task as chat. It has flexible possibilities for styling, customizing and data management


  • Ready-to-use already styled solution for quick implementation;
  • Default and custom media messages;
  • Fully customizable layouts - setting styles out of the box (use your own colors, text appearances, drawables, selectors and sizes) or even create your own custom markup or/and holders for unique behaviour;
  • List of dialogs, including tete-a-tete and group chats, markers for unread messages and last user message view;
  • List of messages (incoming and outcoming) with history pagination and already calculated dates headers;
  • Different avatars with no specific realization of image loading - you can use any library you want;
  • Selection mode for interacting with messages;
  • Links highlighting
  • Easy dates formatting;
  • Your own models for dialogs and messages - there is no converting needed;
  • Ready to use message input view;
  • Custom animations (according to RecyclerView usage).

How to use

To implement all of the features above you can use the following components:


  1. Add jitpack to the root build.gradle file of your project at the end of repositories.
allprojects {
  repositories {
    maven { url '' }
  1. Add the dependency
dependencies {
  implementation 'com.github.stfalcon-studio:Chatkit:[last_version]'


To use with AndroidX you have to set targetSdkVersion for your project to 28 and add following 2 lines in file.



If you are using ProGuard you might need to add rules:

-keep class * extends com.stfalcon.chatkit.messages.MessageHolders$OutcomingTextMessageViewHolder {
     public <init>(android.view.View, java.lang.Object);
     public <init>(android.view.View);
-keep class * extends com.stfalcon.chatkit.messages.MessageHolders$IncomingTextMessageViewHolder {
     public <init>(android.view.View, java.lang.Object);
     public <init>(android.view.View);
-keep class * extends com.stfalcon.chatkit.messages.MessageHolders$IncomingImageMessageViewHolder {
     public <init>(android.view.View, java.lang.Object);
     public <init>(android.view.View);
-keep class * extends com.stfalcon.chatkit.messages.MessageHolders$OutcomingImageMessageViewHolder {
     public <init>(android.view.View, java.lang.Object);
     public <init>(android.view.View);

We were inspired by JSQMessagesViewController library for iOS. In our plans to improve functionality to give Android developers wide opportunities to create fast and good-looking UI for chats in their applications.
