Previously, we presented you with a simple and effective guide to integrating dialogflow bot in a website. In this article, we will be sharing steps to do the same in an Android app. All you need to build a sample chatbot for an android app is Dialogflow and Kommunicate.

Below is an example of Kommunicate Support Bot developed in android using Dialogflow. We actually use this bot on our website. If you wish to see the bot live in action, head here.

The actionable rich messaging powered bot can reply based on whether users are on chat for general queries, technical queries or scheduling a demo.

Step 2: Install Dialogflow integrated Android Chatbot SDK into your app

Add Android SDK to your app

Installing Kommunicate in your Android app is easy and fast. Kommunicate SDK comes with pre-configured dialogflow integration.
Add the following in your app build.gradle dependency:

implementation 'io.kommunicate:kommunicate: 2.1.6'

Initialize SDK
After the Gradle sync has finished with kommunicate dependency, you can initialize the SDK by calling the below method:

Kommunicate.init(context, APP_ID);

You can get the Application ID by signing up on Kommunicate Dashboard.
For full documentation, refer here.

Sample Android app with Dialogflow Chatbot

Here is a sample android app which has dialogflow chatbot integrated. Download and run it in android studio.

Step 3: Launch Android chat app with Dialogflow integrated chatbot

Now, you can send payload to dialogflow through chat screen and get text response from Dialogflow Agent.
Kommunicate provides a ready to use Chat UI so only launching the chat screen is required in this step.

Here are the instructions for launching the chat with Dialogflow bot:

List<String> botList = new ArrayList(); botList.add("bot1"); //enter your integrated bot Ids
new KmChatBuilder(context).setChatName("Support")
                .launchChat(new KmCallback() {
            public void onSuccess(Object message) {
                Utils.printLog(context, "ChatTest", "Success : " + message);

            public void onFailure(Object error) {
                Utils.printLog(context, "ChatTest", "Failure : " + error);

That’s all! Run the Android app and chat with the Dialogflow bot. You can easily integrate Dialogflow in Android apps in a few simple steps. In case you need more information, you can check out the Kommunicate documentation.
