Permissions not asked for on Initialize

[Mick Gallagher]

Hi, The App i am developing requires a number of permissions to be asked for.

I have a location sensor which asks for permission on initialize. That works fine.

I also have Taifuns Telephony manager which i need to work on initialize to get DeviceId.

The App will only ask for the Location sensor permission on start up.

i can access DeviceId elsewhere in the App but need it on initialize. Can anyone help.

Thanks

use the AskForPermission block form the Screen drawer

the telephony manager extension asks for required permissions on first use of a method

Hi Taifun,
The permissions block works fine in my App and returns the IMEI number successfully. It will work anywhere in my App but will not ask for permission where I need it, on Initialze. The location permission is the only one asked for on Initialize.

but will not ask for  permission where I need it, on Initialze.

as already said, use the AskPermission block from the Screen drawer and get the IMEI after that permission has been granted

Hi,
Yes I realise that the blocks should be on screen Initialise and that is where I have been trying to use them but when the app starts it will only ask for location permissions.
I am using this app on a motorola g5 plus
Android 7.
However it works perfectly on a Samsung galaxy j3 Android 5.1.1
Is there any work around for this.
I need it to work on Initialize.
Thanks for your help

[Taifun]

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

Permissions for API < 23 (Galaxy j3 Android 5.1.1) are required (granted) at install-time and since API >= 23 at runtime. As Taifun said, we need to see the relevant blocks ...

Hi,
Rather than putting my blocks on here and maybe making the problem more confusing I hopefully have simplified and made clearer the problem.
In my app I have telephony manager to get the IMEI number of the phone.
I also have a location sensor.
So I used Taifuns Telephony manager example app to highlight the problem.
His app works fine and asks for permission on initialize.
However if I add location sensor to the app it will only ask for location permission on initialize.
If the app is closed then opened again, it will ask for READ_PHONE_STATE.
Hope this helps in illustrating my problem

Hello Mick

The premise is that a picture paints a thousand words :)  If your doctor asks to see your arm, do you only show him/her a written description of it?

What you could do is make a working code snippet (seperate Project) that demonstrates the issue.

[BodyMindPower]

Apparently, it is not possible to request READ_PHONE_STATE or CALL_PHONE at the same time with another permission on Screen.Initialize (especially if the location sensor is used). So, you have to reopen the app to get this request or to ask for permission by a button or something else. See attached aia to play around with it ...

Also Taifun's advice (example) https://puravidaapps.com/telephonymanager.php does not work in this case.

So, if the location sensor is called on Screen.Initialize, the other permissions have to be requested later via buttons (or something else).

Hi Chris,
In most cases I would agree with you but chose the simpler method on this occasion

[Mick Gallagher]

Thanks for your information.
It clears up a lot of questions.
I have had to change the way my app works.
I have already gone down the route of using a button to trigger the permission.
It works well. It would have been nice if it was on Initialize but at the end of the day I still get the same result
Thanks all

Anke, could the "something else" be a Clock Timer enabled on Screen Initialization?

[BodyMindPower]

Hi Chris,

yes, I had already thought about that. But the timer would need to know when the permission was granted to request another permission ... (when to enable the timer?).

Also this does not seem to work:

I think it's possible that this scenario was overlooked at the time the blocks were introduced (they had to be produced in a hurry).

Assigning to Evan, only he knows really.

on the other AI clones this works without any issues ...
