I have been getting a few requests of late for explaining how to do Dialogflow + Android integration for API v2.
Disclaimer: I haven't worked on the Android integration till now. But this article tells you what not to do, and why.
Since I have noticed some online tutorials which are actually more confusing than helpful on this topic, I wanted to clarify something.
Here is an important thing you need to know: if you want to do the integration safely (i.e. without exposing your secret credentials), you cannot put the service account JSON file anywhere on the Android device.
Here is an explanation:
And the linked repo says this:
At this point, you have to choose.
If you don’t care about securing the secret credentials JSON file, then just ignore this article. 🙂 Although, please list out the reasons why you don’t care and make sure you really don’t care for it!
If you do care about this issue, you need to create a backend or cloud function as the commenter suggests. And if you do this, you will need to take the general approach I describe in this article.

"The magic key I needed as a non-programmer" The custom payload generator was the magic key I needed (as a non-programmer) to build a good demo with rich responses in DialogFlow Messenger. I've only used it for 30 minutes and am thrilled. I've spent hours trying to figure out some of the intricacies of DialogFlow on my own. Over and over, I kept coming back to Aravind's tutorials available on-line. I trust the other functionalities I learn to use in the app will save me additional time and heartburn. - Kathleen R Cofounder, gathrHealth
"Much clearer than the official documentation to be honest" Thanks a lot for the advice (of buying and following your videos)! They helped a lot indeed. Everything is very clear when you explain, much clearer than the official documentation to be honest 🙂 Neuraz T Review for Learn Dialogflow CX
"I will strongly recommend this course because even I can learn how to design chatbot (no programming background)" I think Aravind really did a great job to introduce dialogflow to people like me, without programming background. He organizes his course in very clear manner since I have been a college professor for 20 years. It is very easy for me to recognize how great Aravind’s course is! Very use-friend and very easy to follow. He doesn’t have any strong accent when he gives the lectures. It is so easy for me to understand. Really appreciate it. Yes, I will strongly recommend this course because even I can learn how to design chatbot (no programming background) after studying Avarind’s course, you definitely can!
