2. overview Why do we need a Xamarin-Framework?
How we created our Framework.
Using the framework for a test app.
Using the framework for a real app.

3. Why do we need a xamarin-framework?
Xamarin by itself can be overwhelming to beginners.
Makes more reusable code for various Xamarin features.
Simplifies implementing Xamarin features.

4. How we created our framework
The Handler Class
The Ihelper Interface
The Droid Package
The IOS Package

5. The handler class User interacts with this class
Contains an instance of the corresponding IHelper class
Uses this instance to access the device’s features
Ex. Bluetooth
AndroidBluetoothHelper implments IBluetoothHelper
BluetoothHandler will use the instance of AndroidBluetoothHelper to access androidOS specific Bluetooth capabilities.

6. The Ihelper interface
Will define the actions that the user should be able to do (regardless of OS)
This interface will be implemented for each OS (Android/iOS/etc.)
Ex. GPS
IGpsHelper
Double Latitude {get;}
Double Longtitude {get;}
Boolean IsGpsReady {get;}
Event EventHandler LocationUpdated
Event EventHandler GpsReady;

7. The Droid package AndroidHelper class
A specific/concrete implementation of the IHelper interface for Android OS
Ex. Camera
public void StartCameraForPicture(String pictureName, String fileDirectory){ // android sdk features }

8. The ios package IosHelper class
A specific/concrete implementation of the IHelper interface for iOS
Ex. Camera
public void StartCameraForPicture(String pictureName, String fileDirectory){ // iOS sdk features }

9. Using the framework for a test app
An app that uses all of the frameworks features
DEMO

10. Using the framework for a real app
We are making a super top secret app codenamed ‘ProjectEightyFive’
We’ll DEMO it to you, now.
