Interact click on an app button without text

[matt....@gmail.com]

I have a button in an app that I'd like to automate the clicking of, but there is no text associated with the button.
The record action function only shows class:android.widget.ImageView

How can I identify this button?
Thanks

I have the similar question with it.
I've wanted to make an app that it's able to reply Facebook Messenger messages for long.
While my phone was in Android 5, if I use the "record interactions" function and records I click a text box in Messenger, the "UI element ID" exists value. But now, after I upgraded to Android 6, this box is always empties neither in Messenger nor others.
I hope there's someone to help me! Thanks.

An UI element likely has to either have a text or an id, otherwise it's impossible for the Interact block to find it.

But if I click in text input bar in Facebook Messenger, neither in app nor in Chat Head, Automate doesn't catch element text or element id. How can I fix it? Or, is there ways I can reply any messages from Messenger by voice input?

Try a common messaging Send intent, but using something other that a tel URI, a username maybe:

I'm sorry that I'm not understanding. Did you mean I need to put telephone numbers in data uri? If it's true, I'm sorry that it doesn't work. Or, did you mean something else?
Furthermore, there's an app that auto-replies WhatsApp and SMS messages in the forum( http://llamalab.com/automate/community/flows/10009 ). In that case, it just put the contact's name there. I did as same as it for Messenger, but failed.

You'll have to test. The Facebook Messenger app doesn't support "automation" so it may not work at all. But if it does, it's likely a user name, an email address or some kind of user id.

OK, I'll see Facebook's SDK to try. Maybe asking Pushbullet's developer is a good idea, too.(Pushbullet is an app works on Chrome. It's able to reply Messenger and LINE messages and to click or dismiss notifications.)

[Henrik "The Developer" Lindqvist]

Using the Facebook SDK is the best solution if the app doesn't support any kind of intent.

OK, I'll do that. In fact, my phone's manufacturer is ASUS. The built-in dial app supports open Messenger chat head, make a free call and video phones. I'm wondering how does it works too. If I know about that, it'll help a lot!
