Android Question How to access or click on the back key (left arrow at bottom of the smartphone)

[DOM85]

Hello,
Sometime i shell an external app that can be only canceled by clicking on the back key of the smartphone.
Is it possible to click by program on the "back key" ?
Thank you for your help.

It is difficult to achieve. You will need to implement an accessibility service.

Thank you Erel.
Can it be made in B4A ? I don't see how. Only in Java ?

Everything can be made with B4A, if it can be implemented with Java. Whether there is a simple library to use is a different question. There is this one which I'm not sure is compatible with latest requirements: https://www.b4x.com/android/forum/t...th-disabilities-automation-etc.95216/#content
