1. What is Retrofit?
Retrofit is a REST Client library Helper library used in android and java to create an HTTP request
and also process the HTTP response from a REST API.
2. Create an Interface Class.
public interface endpointservice {
// GET AND SET two method use to depend on you.
// put the endpoint file name in GET("") . that means the last name of the base URL
@GET("users.php")
// first my module convert the list then get the value by listresponse()
Call<List<mymodule> listresponse(@Field("User_name"),String name)
}
3. Create the Instance Class.
public class myretrofitInstance{
public final String BASE_URL = "https://example.com/fruit";
Retrofit retrofit = new Retrofit.Builder().baseUrl(BASE_URL )
.addConverterFactory(GsonConverterFactory.create()).build();
}
4. Now Final MainActivity class
// service is initialization in this class
// first initialization instance class.
// second store creates service in the service variable.
// then call the method which is created in service class and pass the parameter.
// now the last process call the enqueue method which is inside two methods 1. onResponse 2. onFailure
// MainActivity
public myretrofitInstance adbs;
endpointservice andpoint = adbs.create(endpointservice .class);
Call<mymodule> call = andpoint.listresponse("API_KEY");
call.enqueue(new Callback<mymodule>(){
@Override
public void onResponse(Call<mymodule> call,Response<mymodule> response)
{
List<mymodule> mymodule = response.body.getResult();
recyclerview.setAdapter(new MyAdapter(mymodule,R.layout.list_item_movie,getApplicationContext()));
}
@Override
public void onFailure(Call<mymodule> call, Throwable throwable)
{
Log.e(TAG, throwable.tostring());
}
});

No comments:
1. First Initialization in build Gradle file
2. Next Step
Click Download google-services.json to obtain your Firebase Android config file (
google-services.json).3. Next Step Create MainActivity java file and initialization firebase authentication in Oncreate() and Onstart()
4. How will log in by Email id with Firebase
what is a push notification ?

No comments:
Definition :
A Notification is a message that pops up on a user's device. Notifications can be triggered locally by an application, or the can be sent/pushed from a server to the user.
- How to push notification work?
1. An app implements push notification and the users confirm that he wishes to receive these notification 👉 swipe for an explaining diagram
2. the user receives a device token, which is generated for example by the Firebase Cloud Messaging server. the device token works as the address that the push notification will be sent to.
3. the server where the backend of the app is running on sends a push notification request to the firebase Cloud Messaging (FCM) server
4. The FCM then sends the push notification to the user's device
on the Firebase websites, you can find information on how to implement push notifications I wanted to share some code as well, but I couldn't make it work yet Maybe I can share some at another time :)
