Xamarin Android in C# and Firebase

In this first lesson, we will look at our final app and its features.

In this lesson, we will start a new project, set our simulator and also change the theme to
@anDroid:style/Theme.Holo.Light.NoActionBar
For this development, we will be working with nexus 4 as a simulator and interface design

In this lesson, we design our outlets and also name them as well the name for our list view

In this lesson, we will rename the activity to ListsActivity and also connect the ListsLayout to its SetContentView as well as accessing our UI elements. We will also code 4 new methods; NewList, ProfileButton, ItemClick and ItemLongClick.

In this lesson, we will do a quick test on list view.

In this non-programming lesson, we will look at how our data is structured.

In this lesson, we will add our Item Class.

In this lesson, we will add our User Class.

In this lesson, we will add our List Class.

In this lesson, we will add our App Data class's starting elements. We would need to introduce and initialize our Current Lists as well as a dummy current user.

In this lesson, we will add our first list, we will not however write it to disk as we still don't have that function.

In this lesson, we will add a new class and call it ListRowCustomAdapter. This custom adapter will help us shape our list view rows. In this lesson, we will use a little cheat and copy the content from an existing code base. We will of course go through the code. We will call the prepare first method form our app data and also get an object of the type ListRowCustomAdapter in our List View and use that to populate the list view.

By now, we have a list view interface where we can view our basic starter lists. Now let's try and add a new list. In here, once everything work, we will face a new issue and that is our app will not maintain its data between two sessions of the application. We will address that in our next section.

In this lesson, we will have a quick look at why we hae to record our data on the disk and what component we should add to do so.

In this lesson, we will add a new method to our app data where all of our lists get written to the disk using a json serialization. To write data, we will also introduce a new OfflineLst.

In this lesson, we will read our data from the disk.

In this lesson, we will learn how to write the user to the disk.

In this lesson we will add our Read user method.

In this lesson, we will adjust our list view to properly read and write data to the disk. We will also make sure if we make a new list, it gets written to the disk.

In this lesson, we will learn how to delete a list by long clicking on it.

In this lesson, we add anew layout for our items interface.

In this lesson, we add a new activity and call it Items Activity. We would then get access to our various elements in the layout in our code.

In this lesson, we will code the navigation to and back from items activity

In this lesson, we will modify our textedit in the layout file to make sure it doesn't pop a keyboard at the begining of the activity.

In this lesson, we will introduce our curList which is the list that we have licked on in the previous activity. We will pass an argument through our intent and fetch the same in our items activity.

In this lesson, we will add a new custom adapter to adapt our items array into a list view. Once again in here, we will use a little cheat to speed up our process.

In this lesson, we change the status of an item by clicking on it, we also write our data to disk after doing that.

In this lesson, we will learn how to add an item by pressing the done button on the text field.

In this lesson, we learn how to delete an item by long clicking on it

In this lesson, we will look back at everything we have done so far and we try to make sense of everything we have done so far and how we could build on those.

In this lesson, we will look at our backend data and why we would need them.

Once we setup everything in our console, we will add the google plist file.

In this lesson, we will add the components and packages needed for firebase to work.

In this lesson, we write the code for our Firebase connection as well as our new OnlineLST

In this lesson we will learn how to change the Firebase rules to public.

We will do a quick test on Firebase in this lesson to make sure it works properly.

In this lesson, we will learn how to add the various profile actions to our login button.

In this lesson, we will use a little cheat to add our register alert view

In this lesson, we will learn how to actually register our user on Firebase back-end.

In this lesson and after registration, we will discuss how to change the local user.

Once user is created, we should write its main data to our backend.

In this lesson, we will learn how to save an entire list to our online back-end.

In this lesson, we will add a new method to show messages to user.

In this lesson, we will read our data once again once the registration is finished.

In this lesson, we will write the alert view for our login menu. This code is little too long and also trivial, so we will use a little cheat in here,

In this lesson we will use our Authentication to login our user to Firebase back-end.

In here we will also set our profile button

Once the lists are compared, we can place them in our current lists.

In this lesson, we will write a comparison method to compare two sets of Lists.

In this lesson, we will learn how to add a new list on cloud.

In this lesson, we will learn how to delete a list from cloud.

In this lesson, we will learn how to add an item on cloud.

In this lesson, we will learn how to delete an item.

In this lesson, we will code our log out method.

This is also a good time to test all of our login, register methods once again. In here, we realize that we need to call our readData once again at the end of the register method. We will also test our application by manually adding an item to the cloud.
