I am working on an app, that reads the users GPS coordinates and changes them just a little bit to then set the new location as mock location. Now this all works but this part of the code crashes my build:
public bool SetMockLocation()
{
bool success = false;
var location = new Location("Test");
_locationManager.AddTestProvider("Test", false, false, false, false, false, false, false, Power.Low, Android.Hardware.SensorStatus.AccuracyHigh);
location.Latitude = Add700ToCoordinates();
location.Longitude = GlobalLongitude;
_locationManager.SetTestProviderLocation("Test", location);
return success;
}
I unfortunately have not been able to find much detail about this at all, all I know that my app Crahses and Visual STudio says:
Java.Lang.SecurityException: GetLocation.GetLocation from uid 10303 not allowed to perform MOCK_LOCATION
So, I decided not to debug the app from my laptop, but to start it from the phone - now with this app set as "Allow mock location".
Here is where it gets wired: Even though my app appears here (yes, I added the permissions) - when I click on it, my phone shows another app that I also have installed and that appears in this menu to be set as mock location. No matter how much I click on my app, my phone always takes the other app.
Nevertheless, as soon as I click on my app and launch it from my phone it simple crashes. Now, did I do something wrong? Im really out of ideas...
Thanks a lot guys!
The error:
Java.Lang.SecurityException: GetLocation.GetLocation from uid 10303 not allowed to perform MOCK_LOCATION
Reveals that you have not asked for permission to mock the location.
You need to add:
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
To your AndroidManifest.xml file.

I code an application in Native Script and I need to use requestPermission after first launch app. I know how to use request permission, but I don't know how to make it work after first running the application. Where I must use request-permission function in app ? In ngOnInit () ?
You may use nativescript-permissions plugin to acquire runtime permissions on Android.
Use hasPermission(permissionName); method to know whether your app already has the permission Or you are yet to acquire it.
Generally it's recommended to ask for permission only when it's absolute necessary. For example, if you want to access micro phone to record anything you would request for permission only when user tries to record one, not upon launch.
You could still ask permissions upon launch, that would work. But in my opinion that could be annoying to the user. May be he is not intended to use that particular feature of the app but just the rest.
// HTML
<Button text="Take Permissions" (tap)="getPermission()"></Button>
// TS File
import * as camera from "nativescript-camera";
getPermission() {
camera.requestPermissions().then(
function success() {
console.log('granted');
},
function failure() {
console.log('failure');
}
);
}
// Search AndroidManifest.xml and add this code in all the occurrences.
<uses-permission android:name="android.permission.CAMERA" />
That's all!
I have a finished application which I would like to make available to run on the iOS and Android platforms. I have tested the application as much as possible and it works without problem. But I know there is always the chance that something might go wrong and I could get an exception.
My question is how can I deal with this or what should I do. What happens on the phone, if a Forms application is deployed and there is an exception.
Would appreciate any advice or even links as to how this is handled.
If an exception is thrown and not handled by your code, the app will stop working (i.e. crash).
In order to handle these crashes we are using MS AppCenter (the successor to HockeyApp/Xamarin AppInsights).
You'll have to create a project there (one for each platform), and add the NuGet package to your projects. Afterwards you can initialize it with
AppCenter.Start("ios={Your App Secret};android={Your App Secret}",
typeof(Crashes)); // you'll get the app secrets from appcenter.ms
Crashes will be logged to AppCenter now and you'll be informed whenever there is a new crash.
Please note that it's best practice (if not required by law), that you ask the user for consent before sending the crash report (see here). You are using the delegate Crashes.ShouldAwaitUserConfirmation for that matter. You could for example show an action sheet with Acr.UserDialogs
private bool AwaitUserConfirmation()
{
// you should of course use your own strings
UserDialogs.Instance.ActionSheet(
new ActionSheetConfig
{
Title = "Oopsie",
Message = "The app crashed. Send crash to developers.",
Options = new List<ActionSheetOption>
{
new ActionSheetOption("Sure", () => Crashes.NotifyUserConfirmation(UserConfirmation.Send)),
new ActionSheetOption("Yepp, and don't bug be again.", () => Crashes.NotifyUserConfirmation(UserConfirmation.AlwaysSend)),
new ActionSheetOption("Nope", () => Crashes.NotifyUserConfirmation(UserConfirmation.DontSend))
}
});
return true;
}
I'm attempting to configure AppCenter.Distribute for in-app updates within my Xamarin Android app. Here is the very basic setup code, which I have in my main launcher activity's OnCreate method (AFTER the base.OnCreate call):
AppCenter.Start (Resources.GetString (Resource.String.appcenter_app_secret), typeof (Analytics), typeof (Crashes), typeof (Distribute));
I was able to get the in-app updates to supposedly initialize. When I first install and open the app, it shows a browser window for one second that says "In-app updates enabled! Returning to app in 1...", then it redirects back to my app. Unfortunately, when I then bump the version name and code and distribute a new build, I don't get a dialog within the app prompting me to update to the new version.
I even tried handling the Distribute.ReleaseAvailable action and showing a custom dialog, and that action isn't invoked either:
Distribute.ReleaseAvailable = OnReleaseAvailable;// Called before AppCenter.Start
private bool OnReleaseAvailable(ReleaseDetails releaseDetails)
{
// Show custom dialog.
Droid.ApplicationContext.Activity.CustomDialogBuilder().Show(new NotificationArgs
{
Title = "New update available!",
Message = "A new version of RPR Mobile, {0} ({1}) is available. Release notes: {2}"
.WithFormat(releaseDetails.ShortVersion, releaseDetails.Version, releaseDetails.ReleaseNotes),
PositiveButtonText = "Update",
PositiveAction = () =>
{
// Notify SDK that user selected to update...
Distribute.NotifyUpdateAction(UpdateAction.Update);
},
HideNegativeButton = releaseDetails.MandatoryUpdate,
NegativeButtonText = "Postpone Update",
NegativeAction = () =>
{
// Notify SDK that user selected to postpone (for 1 day)...
// Note that this method call is ignored by the SDK if the update is mandatory.
Distribute.NotifyUpdateAction(UpdateAction.Postpone);
}
});
// Return true if you are using your own dialog, false otherwise.
return true;
}
I'm wondering what I'm missing. Some questions that may or may not be relevant...
Does it matter whether the AppCenter.Start code executes before or after the base.OnCreate call?
Does it matter whether the activity that AppCenter.Start is called from is running or finished? Because in our case, the main launcher is just a splash screen that closes after a couple seconds.
Is the App Center SDK supposed to poll every few seconds for an update? Or does it check only when opening and closing activities?
It turns out that you have to close and relaunch your app for it to check for new updates. The documentation could be more clear on this...
I know this sounds weird. Is there any way we can open a URI from background tasks in Windows 10 Apps?
I have 2 requirements,
Talk to cortana and it will show you results based on the speech recognition, when user clicks on it, we cannot open the links in browser directly. Instead I am passing the Launch Context to the Foreground app and then using LauchUri I am opening the url in default browser.
Send toast notifications from the App, when user clicks on it, I have requirement to open a url instead opening an app. So, did the same, by passing the launch context to foreground app and then opening the url.
Both scenarios, it just opening url in browser. Here user experience is very poor that user seeing the app open for each action and then opening browser. Please throw some ideas if any possibilities.
thanks in advance.
For your second requirement, you can make Toast Notifications launch a URL!
If you're using the Notifications library (the NuGet package that we suggest you use), just set the Launch property to be a URL, and change the ActivationType to Protocol. You can also do this with raw XML, but that's error-prone.
You can also make buttons on the toast launch a URL too, since they also support ActivationType of Protocol.
Show(new ToastContent()
{
Visual = new ToastVisual()
{
BindingGeneric = new ToastBindingGeneric()
{
Children =
{
new AdaptiveText() { Text = "See the news" },
new AdaptiveText() { Text = "Lots of great stories" }
}
}
},
Launch = "http://msn.com",
ActivationType = ToastActivationType.Protocol
});
I have an app that needs to include a links to a second app in the same phone.
If the app is not installed the link should point to the windows store to install it (that part is working fine).
But if the app is already installed the link should go straight to the app and open it. How can I do that?
The app has two versions one form WP7 and other from WP8. if the solution is different for them please point the difference.
Thanks for the help...
I believe a URI Association is what you want. You should be able to create a different association in your WP7 app and in your WP8 app, and handle them accordingly.
A URI association allows your app to automatically launch when another app launches a special URI.
Also note:
If you are interested only in launching your own apps, consider using
APIs from the Windows.Phone.Management.Deployment namespace. You can
use this API to check for other apps that you’ve published, and then
launch them if they’re installed.
You basically just need to update the WMAppManifest.xml file to include the URI Association and then listen for that URI. Example:
<Extensions>
<Protocol Name="contoso" NavUriFragment="encodedLaunchUri=%s" TaskID="_default" />
</Extensions>
Then you can use a custom URI Mapper to handle your association (full example in top link above):
public override Uri MapUri(Uri uri)
{
tempUri = System.Net.HttpUtility.UrlDecode(uri.ToString());
// URI association launch for contoso.
if (tempUri.Contains("contoso:ShowProducts?CategoryID="))
{
// Get the category ID (after "CategoryID=").
int categoryIdIndex = tempUri.IndexOf("CategoryID=") + 11;
string categoryId = tempUri.Substring(categoryIdIndex);
// Map the show products request to ShowProducts.xaml
return new Uri("/ShowProducts.xaml?CategoryID=" + categoryId, UriKind.Relative);
}
// Otherwise perform normal launch.
return uri;
}
Hope this helps!
Is the secondary app one that you have created? If so, do something like this:
IEnumerable<Package> packages = InstallationManager.FindPackagesForCurrentPublisher();
foreach (Package package in packages)
{
if (package.Id.ProductId.ToString().ToLower() == "product id of secondary app")
{
//Launch the app
package.Launch();
}
}
Make sure that your publisher ids match in the WMAppManifest for both apps.
If this secondary app was published by someone else, you'll need to use a custom Uri schema. The app needs to have this feature added by the developer, you can't just launch any app.
