Tutorial Contents

1.-We create a Project and we put the name creating the Project

2.-We create two activities with their xml one called LoginActivity and MainActivity

In the manifest file

we defined the two activitys with two special configurations as intent-filter

In the activity MainActivity

we indicate that it is the main activity and that is the one that is going to be launched every time the application starts

In the LoginActivity

we indicate four inten-filters with possibility of view, navigable and by default

in the OnCreate event in MainActivity

we create a variable of type string with the url with the authentication path then we made a Uri type parse Afterwards we created an Intent with the uri in we started the activity of LoginActivity this redirects us towards the steemconnect authentication service

In the activity_main (Layout)

we will only place a simple button to make the call to the next activity

LoginActivity.java

verify if the received Intent is different from null then we created a Uri to get it from the Uri then we verify if it is different from null and we get the username of the getQueryParameter ("username") method later we set it in the textview of the LoginActivity obtaining the username indicates that we are authenticated as we can also receive the code and many more values ​​that will serve us for future implementations such as voting, posting, commenting among others

In the layout of the LoginActivity

We will only create a Simple TextView that will serve us to show the user logged in

#SteemConnect in action!

#MainActivity

#SteemConnect Validating From Browser

#SteemConnect From from Browser

Soon I will launch a more advanced version 2 of autenticacoin with steemconnect explaining how to create an official app for the steemconnect service
