I'm developing using JDE 4.5 which doesn't contain the PERMISSION_RECORDING,
and it's denied by default in 4.6 and higher devices.
So I want my application to have this permission or all the possible permissions that it can get.
Thanks in advance.
You can't set app permissions pro grammatically. What you can do is force Request Permission dialog to appear, see How to - Display custom messages in the request permission dialog
So what you can do is do some test recording on application startup, then Request Permission dialog will come up. It would come up anyway, but on startup this will be more in place, and more, you can set your own message text there.
UPDATE
If permission is set to Deny than there will be no Promt Dialog on denied action.
Then you can use ApplicationPermissionManager to invoke permission request:
ApplicationPermissionsManager manager = ApplicationPermissionsManager
.getInstance();
int current = manager
.getPermission(ApplicationPermissions.PERMISSION_SCREEN_CAPTURE);
if (current != ApplicationPermissions.VALUE_ALLOW) {
ApplicationPermissions permissions = new ApplicationPermissions();
permissions.addPermission(ApplicationPermissions.PERMISSION_SCREEN_CAPTURE);
manager.invokePermissionsRequest(permissions);
}

Can I register my Swift app to an OS notification about location permission change?
For example, let's say that the current state is denied and then the user is switching to the settings and change the permission to always and then opens my app again. Can I tell that my user had changed the permission and get both the old and the new one or is it too much to ask :) ?
Something like ABAddressBookRef ntificationaddressbook = ABAddressBookCreate(); ABAddressBookRegisterExternalChangeCallback(ntificationaddressbook, MyAddressBookExternalChangeCallback, self);
I'm working in a ios recursive function to send the message 'My App need request your location' each time that the user turn off his GPS then, the message should appears again requesting his location.
I'm just using:
public bool LocationServicesEnabled {
get {return CLLocationManager.LocationServicesEnabled;}
}
public bool IsAuthorized {
get {return CLAuthorizationStatus.Authorized == _authstatusLast;}
}
With those functions, the first one return me is the Service is Enable and the second one if the user autorizate it.
Just now, I can do something similar to:
if(_locationServiceEnalbed && IsAuthorized){
Manager = new LocationManager();
Manager.StartLocationUpdates();
}
But is not requesting me my location again.
How I can display the message again requesting the user location?
According to Apple, if they deny access to your app, you can request it again by trying to start the location services
If it returns NO and you attempt to start location services anyway,
the system prompts the user to confirm whether location services
should be re-enabled. Because the user probably disabled location
services on purpose, the prompt is likely to be unwelcome.
However, a more friendly approach might be to display a message that this feature of your app is disabled until they grant permissions to use GPS, and to direct them to the Settings menu where it can be re-enabled
When my app is launched it requests to use location services.
If a user selects 'Don't Allow' I prompt again letting them know that Location Services are required for the best experience and they can enable in the settings app.
If a user does not allow and still creates an account, the main screen will not fully function without the location feature part.
From this point, if I manually enable in the Settings app I'm still not getting the main page to pick up the current location.
How do I detect that location services have been enabled from the Settings App?
Is there a method I need to enforce again from the AppDelegate?
You can tell if location has been enabled for your app using CLLocationManager.AuthorizationStatus, which returns a member of the CLAuthorizationStatus enum. If location is disabled completely, your app won't be authorized, so you know everything you need to know.
let authorization = CLLocationManager.authorizationStatus()
if authorization == .AuthorizedWhenInUse || authorization == .Authorized {
...
}
If you request authorization using CLLocationManager and the user denies it, you can't cause the window to come up again.
From a UX point of view, be careful about nags as well. Communicate clearly that your app benefits from using location, but try to avoid browbeating the user about it.
See also how to determine when settings change on ios to have your app retry location access right after a user (hopefully) enabled it.
When the user launches the app for the first time and attempts to login, they are prompted with the iOS dialog - "Turn On Location Services".
I need to capture when the user clicks "cancel". Is there a Notification sent? If so, what is its name? I've been unable to locate it.
The CLAUthorizationStatus is kCLAuthorizationDenied when Location Services are Disabled OR the user clicked "Don't allow". When the user clicks "Cancel", it does not fire the authorizationChange event. When user clicks "Cancel", the app just hangs.
Short answer: You can't catch that notification. You can infer about the user choice and act consequently by using CLLocationManager methods (the longer answer below).
Longer answer:
Firstly, welcome on Stack Overflow. Before kindly posing your question, and trying to be collaborative with people that are here to help, it's a good idea to search if somebody else previously posed the same question.
A brief search gave (just to mention some of them):
How to handle “Cancel” button on Alert pop up for Location services
How to get location services to reprompt the user for location permission if they accidentally refused it?
locationManager:didFailWithError: not called if user Location Services are off
How to prompt user to turn on Location Services…again
How can I prompt the user to turn on location services after user has denied their use
How to ask permission from user for second time to allow to access the current location?
Now, let's try to summarize them all, starting from iOS docs:
If your app relies on location services to function properly, you should include the UIRequiredDeviceCapabilities key in the app’s Info.plist file. You use this key to specify the location services that must be present in order for your app to run. The App Store uses the information in this key from preventing users from downloading apps to devices that do not contain the listed features.
Important: If your app uses location services but is able to operate successfully without them, do not include the corresponding strings in the UIRequiredDeviceCapabilities key.
So, if your app really needs to access the user's position you should add location-services and eventually gps to UIRequiredDeviceCapabilities.
Then, somewhere in your code - when needed, you have to check if the location services are enabled.
[CLLocationManager locationServicesEnabled]
they may be disallowed for three reasons:
The user can disable location services in the Settings app.
The user can deny location services for a specific app.
The device might be in Airplane mode and unable to power up the necessary hardware.
You are interested in the second case: the user refused to allow your app to use the location services.
Again, from the docs:
Important: In addition to hardware not being available, the user has the option of denying an application’s access to location service data. During its initial uses by an application, the Core Location framework prompts the user to confirm that using the location service is acceptable. If the user denies the request, the CLLocationManager object reports an appropriate error to its delegate during future requests. You can also check the application’s explicit authorization status using the authorizationStatus method.
[CLLocationManager authorizationStatus]
That may return:
kCLAuthorizationStatusNotDetermined if the user has not yet made a choice regarding whether this application can use location services.
kCLAuthorizationStatusRestricted this application is not authorized to use location services. The user cannot change this application’s status, possibly due to active restrictions such as parental controls being in place.
kCLAuthorizationStatusDenied The user explicitly denied the use of location services for this application or location services are currently disabled in Settings.
kCLAuthorizationStatusAuthorized This application is authorized to use location services.
If[CLLocationManager locationServicesEnabled] returns NO and you attempt to start location services anyway (i.e. calling [locationManager startUpdatingLocation]), the system prompts the user to confirm whether location services should be re-enabled. Given that location services are very likely to be disabled on purpose, the user might not welcome this prompt.
I suppose you know, and did all the previous steps (I'm only sure you checked the authorizationStatus). You refused to show us the significant code of your app so I can only suppose the overall logic behind. Now you said your app hangs. This should be because you didn't catch the error properly? Catching the error is the way to re-prompt the user, if you wish.
After calling [locationManager startUpdatingLocation], if not authorized, your delegate should define a locationManager:didFailWithError: in order to catch the kCLErrorDenied.
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
You may show, at this point, a UIAlert to insist asking the user to give you access to its position, or trigger a change in the UI or whatever you like.
Final notes
I hope you understand why I was asking for the code: the reason was to offer you an alternative solution instead of reply "You can't catch the 'Cancel' notification".
If this answer does not satisfy your question please elaborate why you need to catch the pushing of the "Cancel"/"Do not allow" button, so we can provide alternatives.
Clearly my advice is to not annoy people to death by continuously ask them for enabling location services if they don't want.
Post scriptum: Maybe that the answer looks pedantic and obvious in certain parts if not all to you, but we are here to provide answers also for future readers.
I am developing an application where I am recording voice and storing the recording in file:///home/. For this purpose, when i click on record button, it asks for a permission
Application Permission
The application has requested to record
Allow Deny
On clicking Allow, it asks for following permission :
Application Permission
The application has requested a file connection to listenn to messages
Do not ask for file
Do not ask for file to listen to messages
Allow Deny
On hitting allow, it begins recording and simultaneously saves the recording in SDCard.This works fine in 9250 Storm.
But when I am testing the same app in 9700 & 9300 it asks only for recording permission and not for file saving, thus not saving my file. Am I missing some settings in phone??
You may ask for the requested permissions explicitly gain it before entering the process.
here is a code sample to do this
ApplicationPermissionsManager manager = ApplicationPermissionsManager.getInstance();
int current = manager.getPermission(ApplicationPermissions.PERMISSION_FILE_API);
if (current != ApplicationPermissions.VALUE_ALLOW) {
ApplicationPermissions permissions = new ApplicationPermissions();
permissions.addPermission(ApplicationPermissions.PERMISSION_FILE_API);
manager.invokePermissionsRequest(permissions);
}
