As soon as the software for Android cam initiate, it should find out if the user are finalized in

Step One: Handle Consumer Sign-In

In that case, the app should go forward and display the belongings in the talk area. If not, it must reroute the consumer to either a sign-in display or a sign-up display screen. With FirebaseUI, producing those displays takes a lot less code than you may imagine.

In the onCreate() approach to MainActivity , find out if an individual is already closed in. For this, check if current FirebaseUser object is not null . If it’s null , you should make and configure an Intent item that opens a sign-in task. To take action, utilize the SignInIntentBuilder class. After the intention is ready, you must release the sign-in activity by using the startActivityForResult() method.

Remember that the sign-in task furthermore allows new users to sign up. Therefore, you don’t need to create any extra rule to carry out consumer enrollment.

Perhaps you have realized from inside the preceding code, when the user is finalized in, we 1st showcase a Toast inviting the user, right after which phone a technique called displayChatMessages. For the time being, just make a stub for it. We will end up being incorporating laws to it later.

Once the individual have finalized in, MainActivity will get an end result by means of an intention . To manage it, you need to override the onActivityResult() way.

If the outcome’s laws try RESULT_OK , it indicates an individual provides signed in successfully. If that’s the case, you must phone the displayChatMessages() system once more. Normally, call finish() to close the app.

Step Two: Deal With Consumer Sign-Out

By default, FirebaseUI uses Intelligent Lock for Passwords. Thus, as soon as customers check in, they’ll stay signed in even when the app is restarted. To allow the customers to signal completely, we’re going to now add a sign-out option to the overflow diet plan of MainActivity .

Make a brand new menu reference document called main_menu.xml and incorporate a single item to they, whoever subject feature is set to signal . The contents of the document need to look like this:

To instantiate the selection reference inside MainActivity , override the onCreateOptionsMenu() approach. After that phone the inflate() technique of the MenuInflater item.

Then, override the onOptionsItemSelected() way to manage click events throughout the eating plan object. Within the technique, it is possible to phone the signOut() method of the AuthUI course to sign an individual . Due to the fact sign-out procedure try performed asynchronously, we are going to also add an OnCompleteListener to it.

The moment the individual enjoys finalized , the app should nearby instantly. This is why why you discover a call toward finish() means into the rule above.

5. Make A Design

In order to shop the chat communications in Firebase real-time databases, you should generate a product for them. The layout of chat information, which we created before within guide, features three vista. To populate those panorama, the product as well must-have about three industries.

Generate an innovative new Java class also known as ChatMessage.java and create three member variables to it: messageText , messageUser , and messageTime . Furthermore, create a constructor to initialize those variables.

To make the model compatible with FirebaseUI, you need to also add a default constructor to they, in conjunction with getters and setters for all your associate variables.

6. Post A Speak Message

Inside listener, you have to initially see a DatabaseReference object utilizing the getReference() approach to the FirebaseDatabase course. You can then contact the push() and setValue() solutions to create brand-new cases of the ChatMessage class with the real-time databases.

The ChatMessage instances must, needless to say, be initialized with the items in the EditText in addition to screen label for the currently signed-in Geek Sites dating apps user.
