How to get data from Android application GUI?

Question

Android

I need to get the data that the android application A displays. how to parse the text of the activation. The first thing that comes to mind is reverse engineering. But this is quite difficult, especially if it turns out that application A verifies its signature, and even does it in native code.
I see the ideal solution to write application B, which will imitate the user's work (like an autoclicker) with application A.
There are two questions:
1. Is it generally possible on Android to write such an application B that will click and scroll the application. Those. is there such an API?
2. Is it possible to somehow get the text (not the screen) from the activation of application A while it is running, without resorting to reverse engineering?

Answer 1

"Is it possible to somehow get the text (not the screen) ... without resorting to reverse engineering?"
No. Since the display of the activity is done using the view, and each view draws itself on the graphics canvas. The result is a "picture".
Having reached these Views, you will not be able to get the text without knowing which properties contain what you need, this is only through reverse engineering.
