Data passing in multiple screens from one activity to another using Xamarin in Android

Introduction :-
In this Article, we will see how to create multiple screens in Android using Xamarin and pass data between them.
Android applications consist of a set of loosely coupled screens, represented by Activity classes.
Since each Activity is essentially decoupled from others, there needs to be a way to launch them and optionally pass data to them. On Android this is accomplished using Intents.

Intents are the classes that describe a message, both what the desired action of the message is and a data payload to send along with it. They are commonly used within applications to launch Activities. To launch a new Activity, we create a new Intent, set the Context and the Activity class to launch and then tell the OS to handle the Intent, which launches the Activity. Continue reading

GPS Location Tracker using Xamarin

Mobile devices are smart enough to provide the geo-location coordinates by consuming the GPS API embedded inside.
Let’s get the geo-coordinates and a street address which is close to the location using Xamarin. In the below example I have demonstrated the same in Android environment.

Following are few steps

Step #1
After creating a new Xamarin Android app add some common permission in AssemblyInfo.cs

[assembly: UsesPermission(Manifest.Permission.Internet)]
[assembly: UsesPermission(Manifest.Permission.AccessFineLocation)]
[assembly: UsesPermission(Manifest.Permission.AccessCoarseLocation)]

Step #2 Continue reading
