To arrange the project to work with the Firebase platform, opened the Firebase helper windows by clicking on methods > Firebase.

While using the Firebase system, it is usually a smart idea to combine Firebase statistics on the plan. For that reason, inside the Firebase helper panel, go right to the statistics section and press Log an Analytics event.

Subsequent, push on the hook up to Firebase key and make sure which Create brand-new Firebase plan option is chose. Once the connections is initiated, press the Add Analytics towards your software option.

At this juncture, the Android Studio visualize is actually incorporated with Firebase statistics and able to use with all of other Firebase facilities.

2. Add Dependencies

We are going to be using two libraries inside Android os talk software laws project: FirebaseUI as well Android layout support room. Therefore, exposed the build.gradle file of this app component and add all of the following make dependencies to it:

Spring the Sync At this point option to upgrade your panels.

3. Explain Layouts

The activity_main.xml document, that is certainly previously sure to MainActivity , specifies the belongings in home display of this application. To phrase it differently, it will probably stand for the chatroom.

Similar to other-group chatting apps on the market today, our very own Firebase chat room Android application has listed here UI items:

  • an email list that presents most of the class talk communications in chronological purchase
  • an insight field in which the owner can type in an innovative new content
  • a switch the individual can spring to publish the message

Thus, activity_main.xml must have a ListView , an EditText , and a FloatingActionButton . After placing them inside a RelativeLayout widget, your very own structure XML will look in this way:

Be aware that I put the EditText widget inside a TextInputLayout widget. This includes a drifting tag for the EditText , which happens to be vital if you need to adhere to the information of product layout.

Since the structure of the house display is in a position, we can start working on creating a layout for your chatting information, that will be goods within the ListView . Start with promoting a order XML data labeled as communication.xml, whose base component happens to be RelativeLayout .

Once the app for droid chatting begins, it has to verify that the person try signed in. If you do, the app should go in front and display the belongings in the chatroom. If not, it should redirect anyone to either a sign-in display screen or a sign-up monitor. With FirebaseUI, developing those screens gets significantly less code than you possibly might think of.

Inside the onCreate() technique of MainActivity , verify that you is finalized in. To get this done, check if the latest FirebaseUser thing just isn’t null . Whether it’s null , you should write and assemble an Intent thing that starts a sign-in exercise. To accomplish this, make use of SignInIntentBuilder class. As soon as intention is prepared, you must introduce the sign-in exercises using the startActivityForResult() approach.

Note that the sign-in interest furthermore brings new registered users to subscribe. As a result, there’s no need to create any added laws to handle customer enrollment.

Use in this article rule toward the onCreate() process:

As you care able to see inside preceding signal, if your customer is already finalized in, all of us initially present a Toast inviting you, thereafter name one way named displayChatMessages. For now, merely make a stub for it. We are going to generally be incorporating code this eventually.

Once the individual have closed in, MainActivity will receive an outcome like an objective . To handle it, you must override the onActivityResult() strategy.

When benefit’s code is RESULT_OK , it means the individual enjoys closed in properly. If that’s the case, it is vital that you name the displayChatMessages() system again. Usually, contact finish() to shut the application.
