Android Permissions Problem

BiL-ink · March 28, 2017, 3:46pm

Hi everybody.

Currently, we are working on an application and facing some critical permissions issues which prevent application to work because some of them are “must have”, due to the application content. To be more precise, we ask user for the permissions in the code below:

&nbsp;usesPermissions = &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; "android.permission.INTERNET", &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; "android.permission.ACCESS\_NETWORK\_STATE", &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"android.permission.VIBRATE", &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"android.permission.CAMERA", &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; "android.permission.WRITE\_EXTERNAL\_STORAGE", &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"android.permission.ACCESS\_FINE\_LOCATION", &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; "android.permission.ACCESS\_COARSE\_LOCATION", &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; },

Application is 99% done and we are in the beta testing phase and our testers, just as we have, run into next problem:

popup screen for granting permission fails to show. Let me explain. In some caises, there’s no problem and everything works just fine. On the other hand, app sometimes doesn’t require all permission we want (in most cases, it’s the location permission, or sometimes, the camera permission).

We tried all the things mentioned on Corona web pages, like the ones in the link bellow and it’s doesn’t seem to work at all.

We are currently checking if the permission is granted and based on the response trying to get it or continue to use the app and it also sometimes fails to do the job. Even though, for example, the location permission isn’t granted and we check on the app start before doing everything if it is, the permission popup fails to show. Based on the results from our beta testers we assume the problem isn’t affected by the Android version.

function hasLocationPermission() &nbsp;&nbsp; &nbsp;if system.getInfo( "environment" ) == "simulator" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return true &nbsp;&nbsp; &nbsp;else &nbsp;&nbsp;&nbsp; -- Check to see if the user has previouslly granted permissions &nbsp;&nbsp;&nbsp; local grantedPermissions = system.getInfo( "grantedAppPermissions" ) &nbsp;&nbsp; &nbsp;local hasLocationPermissionVar = false &nbsp;&nbsp;&nbsp; -- Check for the "Camera" group permission &nbsp;&nbsp;&nbsp; for i = 1,#grantedPermissions do &nbsp;&nbsp; &nbsp;--print (grantedPermissions[i]) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if ( "Location" == grantedPermissions[i] ) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hasLocationPermissionVar = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;break &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp; return hasLocationPermissionVar &nbsp;&nbsp; &nbsp;end end &nbsp; local function hasCameraPermission() &nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; -- Check to see if the user has previouslly granted permissions &nbsp;&nbsp;&nbsp; local grantedPermissions = system.getInfo( "grantedAppPermissions" ) &nbsp;&nbsp; &nbsp;local hasCameraPermissionVar = false &nbsp;&nbsp;&nbsp; -- Check for the "Camera" group permission &nbsp;&nbsp;&nbsp; for i = 1,#grantedPermissions do &nbsp;&nbsp; &nbsp;--print (grantedPermissions[i]) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if ( "Camera" == grantedPermissions[i] ) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hasCameraPermissionVar = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;break &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp; end &nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; return hasCameraPermissionVar end function locationCheck() &nbsp;&nbsp; &nbsp;if ( system.getInfo( "platform" ) == "android"&nbsp; ) then &nbsp;&nbsp; &nbsp; print("lokacijalalalal") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local locationPermissionGranted = hasLocationPermission() &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if not locationPermissionGranted then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- If phone permission is not yet granted, prompt for it &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local permissionMap = native.newMapView( Global.screenWidth + 2\*Global.visakX + 500, Global.screenHeight + 2\*Global.visakY + 500, 20, 20 ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if permissionMap then &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local currentLocation = permissionMap:getUserLocation() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;display.remove(permissionMap) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;permissionMap = nil &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--cameraCheck() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;checkForInternetOnStart() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;else &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- We already have the needed permission &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--cameraCheck() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;checkForInternetOnStart() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; return true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;end end function cameraCheck() &nbsp;&nbsp; &nbsp;if ( system.getInfo( "platform" ) == "android"&nbsp; ) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local cameraPermissionGranted = hasCameraPermission() &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if not cameraPermissionGranted then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- If phone permission is not yet granted, prompt for it &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;media.capturePhoto( { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; destination = { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; baseDir = system.DocumentsDirectory, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; filename = "req.jpg", &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; type = "image" &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; } &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;} ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;locationCheck() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;else &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;locationCheck() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- We already have the needed permission &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;end end

We would appreciate some help since we’ve made 99% of the app and have no other idea how to solve the issue.

Thank you and best regards,

Luka and Marijan!

Hi,

First of all: I’m certainly no Corona expert and currently have my own camera permission issues.

In CameraCheck() you write "prompt for camera permissions, but I don’t see where you do that. Do you mean that media.capturePhoto() should do this automatically? I haven’t gotten that to work.

Don’t you have to ask permissions specifically? Something like this?

 -- Permission denied. Ask for camera permission local options = { appPermission = "Camera", urgency = "Critical", listener = showPopupCB, rationaleTitle = "The app needs camera access!", rationaleDescription = "The app needs camera access to be able to scan QR codes and take pictures. Please give the app access to the camera!", settingsRedirectTitle = "Alert", settingsRedirectDescription = "The app needs camera access to be able scan QR codes and take pictures. Please give the app access to the camera!" } native.showPopup( "requestAppPermission", options )
