Android Question Click button in some option of phone setting programmatically

You can not control Systemsettings and also not Clicking there.

The best you can do is to send the user to the Sestting and then the User must clear data or whatever.
You need to find a java code which opens the desired Settings.
Send an Intent with the correct values (see last sentence).

It is possible to accept an accessibility service, i saw an application yesterday that can do it.

I saw this question already in a other thread from you.

In how many threads you want to ask this question?

Yes, it may be possible with the accessibility service.
But i cant help with this. I only checked the lib once.

Additionally you should expect that most of the users here do not have any experience with the accessibility service.
