    I have to fix an bug with my App on Android 9.
    So I did get a Samsung A8 with Android 9 OS.

    After installing and starting the B4A Bridge I get the message about setting the Unknown Apps message on my device.

    In Android 9 this is done by giving the B4A bridge app the permission.
    I have done that but B4A Bridge keeps throwing the message "Please enable installation of non-market applications......".

    Unfortunally the start button keeps grayed out.
    Anyone an idea to solve this?

    I didn't find anything yet on this subject.

    A workaround for now....

    I installed the app B4A-Bridge Plus from Gunther Gabriel.
    It also keeps throwing the message but the Start Wireless button is Enabled.

    B4A does connect to this old B4A-Bridge and I am able to deploy the app from my computer.

    This is really a B4A Bridge bug. Hope that it will be fixed soon.

    That's odd because B4A-Bridge from the Store works fine on my Xiaomi Mi Max 3 with Android 9 after giving it the permission initially.

    I have Android 9 security patch (01 march 2019) installed on this phone.
    Maybe it has a little too much security in it.

    I think someone should look into it.
    Anyway... I am able to fix the bug now. :)

    I have no problem with mine on Android 9 on my Note 8 which just updated a couple of days ago finally. (Thanks verizon....... better late than never I guess)

    BUT I think I installed the bridge the day before it updated to 9. So evidently it just carried over permissions from the older version.

    I will keep the buttons enabled as this is the second report of such issue.

    I also have the problem with b4a-bridge on note 8 with android9 installation of the bridge app occurred after updating the note8. Can Gunther Gabriel's B4A-Bridge Plus be used?
