Firebase RealTime Database(SetData)

This article will help you to make an android app with Firebase RealTime Database to put data. The screenshot of the main layout is given below..

Above the photo there are some data field where we will set value and that value will store in firebase realtime database. Let's see the processes..

You should to create another activity named SecondActivity.java with activity_second.xml otherwise this code will show some error. On the other hand you should to connect with Firebase using the following command-

Go to Tools option;
Click on Firebase icon;
Now connect to RealTime Database;
Then add the code according to your own app..

That's enough if you perform this technique correctly then it will show a output as well as you saw in the above image..

[N.B.: In this app code I have used some resources drawable like image and color name. You have ensure the same drawable and color otherwise your compiler will show error to you.. So be accurate and run this code.. Have a good practice.. Thank you..]
