I cant seem to get geo location to work on Android just seem to get the following bug.
[INFO] : dalvikvm: Could not find method android.app.Activity.checkSelfPermission, referenced from method ti.modules.titanium.geolocation.GeolocationModule.hasLocationPermissions
[WARN] : dalvikvm: VFY: unable to resolve virtual method 32: Landroid/app/Activity;.checkSelfPermission (Ljava/lang/String;)I
[INFO] : dalvikvm: Could not find method android.app.Activity.requestPermissions, referenced from method ti.modules.titanium.geolocation.GeolocationModule.requestLocationPermissions
[WARN] : dalvikvm: VFY: unable to resolve virtual method 82: Landroid/app/Activity;.requestPermissions ([Ljava/lang/String;I)V
My code is as follows.
Ti.Geolocation.purpose = "Please allow us to find you.";
//Ti.Geolocation.showCalibration = false;
if (OS_ANDROID) {
Titanium.Geolocation.Android.LocationProvider = Ti.Geolocation.PROVIDER_GPS;
}
Ti.Geolocation.accuracy = Ti.Geolocation.ACCURACY_BEST;
Ti.Geolocation.distanceFilter = 10;
Ti.Geolocation.requestLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS, function(e) {
console.log(e);
if (!e.success || e.error) {
var dialog = Ti.UI.createAlertDialog({
message : 'You do not have location permissions enabled.',
ok : 'Got it',
title : 'Important'
});
dialog.addEventListener('click', function(e) {
if (OS_IOS) {
Ti.Platform.openURL('app-settings:');
}
if (OS_ANDROID) {
var intent = Ti.Android.createIntent({
action : 'android.settings.APPLICATION_SETTINGS',
});
intent.addFlags(Ti.Android.FLAG_ACTIVITY_NEW_TASK);
Ti.Android.currentActivity.startActivity(intent);
}
});
dialog.show();
return;
}
Titanium.Geolocation.getCurrentPosition(getGeoPosition);
});
When i run this it just stales been at this for hours now trying to debug so close to just giving up tried everything i can think of.
Appcelerator 5.1.2.GA
FULL CODE TO TEST
function getGeoPosition(_event) {
console.log(_event);
alert(JSON.stringify(_event));
}
Ti.Geolocation.purpose = "Please allow us to find you.";
Ti.Geolocation.accuracy = Ti.Geolocation.ACCURACY_BEST;
Ti.Geolocation.distanceFilter = 10;
/**
* Event listener added in the view.
* Fired when user taps on the Ti.Geolocation button.
*/
function geolocation() {
// The new cross-platform way to check permissions
// The first argument is required on iOS and ignored on other platforms
var hasLocationPermissions = Ti.Geolocation.hasLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS);
if (hasLocationPermissions) {
alert('You already have permission.');
Titanium.Geolocation.getCurrentPosition(getGeoPosition);
}
// On iOS we can get information on the reason why we might not have permission
if (OS_IOS) {

// Always returns AUTHORIZATION_UNKNOWN on iOS<4.2
var locationServicesAuthorization = Ti.Geolocation.locationServicesAuthorization;
if (locationServicesAuthorization === Ti.Geolocation.AUTHORIZATION_RESTRICTED) {
alert('Because permission are restricted by some policy which you as user cannot change, we don\'t request as that might also cause issues.');
} else if (locationServicesAuthorization === Ti.Calendar.AUTHORIZATION_DENIED) {
alert('You denied permission before');
}
}
// The new cross-platform way to request permissions
// The first argument is required on iOS and ignored on other platforms
Ti.Geolocation.requestLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS, function(e) {
if (e.success) {
// Instead, probably call the same method you call if hasLocationPermissions() is true
alert('You granted permission.');
} else if (OS_ANDROID) {
alert('You denied permission for now, forever or the dialog did not show at all because it you denied forever before.');
} else {
// We already check AUTHORIZATION_DENIED earlier so we can be sure it was denied now and not before
Ti.UI.createAlertDialog({
title : 'You denied permission.',
// We also end up here if the NSLocationAlwaysUsageDescription is missing from tiapp.xml in which case e.error will say so
message : e.error
}).show();
}
});
}
geolocation();
// Handle the URL in case it resumed the app
Ti.App.addEventListener("resume", function() {
geolocation();
});

UPDATE MANAGE TO GET IT WORKING BUT WHY!!!!
Ok so i managed to get it working by going into my locations setting and turing them off and then on again and click Agree???? weird cant be right?
This is soooo annoying i have to do this everytime to get the locations services to work?
Update i think one of the main reasons i have been getting a issue is because i was requesting permissions on every load on the post layout event listener this seems to fix the issue.
var hasLocationPermissions = Ti.Geolocation.hasLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS);
if (hasLocationPermissions) {
alert('You already have permission.');
Titanium.Geolocation.getCurrentPosition(getGeoPosition);
} else {
Ti.Geolocation.requestLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS, function(e) {
if (e.success) {
Titanium.Geolocation.getCurrentPosition(getGeoPosition);
} else if (OS_ANDROID) {
alert('You denied permission for now, forever or the dialog did not show at all because it you denied forever before.');
} else {
// We already check AUTHORIZATION_DENIED earlier so we can be sure it was denied now and not before
Ti.UI.createAlertDialog({
title: 'You denied permission.',
// We also end up here if the NSLocationAlwaysUsageDescription is missing from tiapp.xml in which case e.error will say so
message: e.error
}).show();
}
});
}
Still seem to be getting all sorts of other issues where GPS isnt activate each time ill keep at this and report back with updates.
