Add Required Code

• Server Key = Firebase Console -> Select Project -> Project settings -> Cloud Messaging -> Copy Server Key

// JAVA
public class MainActivity extends AppCompatActivity {
    private static String serverKey = "";   
    @Override    
    protected void onCreate(Bundle savedInstanceState) {    
        super.onCreate(savedInstanceState);    
        setContentView(R.layout.activity_main);  
        // FCMSend Initialization  
        FCMSend.SetServerKey(serverKey);
    }
}  

// KOTLIN
class KotlinMainActivity : AppCompatActivity() {  
      private val serverKey = "" 
      override fun onCreate(savedInstanceState: Bundle?) { 
            super.onCreate(savedInstanceState) 
            setContentView(R.layout.activity_kotlin_main)
            // FCMSend Initialization
            FCMSend.SetServerKey(serverKey) 
      }
}  

Get Device Token and Subscribe To Topic

Get Device Token

Get device Token

// JAVA  
FirebaseMessaging.getInstance().getToken() 
      .addOnCompleteListener(new OnCompleteListener<String>() {
          @Override    
          public void onComplete(@NonNull Task<String> task) {
              if (!task.isSuccessful()) { return; } 
              String token = task.getResult(); 
          }
      });  

// KOTLIN  
FirebaseMessaging.getInstance().token    
    .addOnCompleteListener(OnCompleteListener { task ->    
        if (!task.isSuccessful) {    
            return@OnCompleteListener    
        }    
val token = task.result })  

Subscribe To Topic

Subscribe Topic

// JAVA  
FirebaseMessaging.getInstance().subscribeToTopic("<Topic Name>")
    .addOnSuccessListener(new OnSuccessListener<Void>() {  
        @Override    
        public void onSuccess(Void aVoid) {  
        System.out.println("Subscription successful"); 
        }
    });  

// KOTLIN  
FirebaseMessaging.getInstance().subscribeToTopic("<Topic Name>")
    .addOnSuccessListener {  
        println("Subscription successful")
    }  

Usage Java - Kotlin

Send Push Notifications By Device Token

// JAVA  
HashMap<String, String> data = new HashMap<>(); 
data.put("key1", "data 1"); 
data.put("key2", "data 2"); 
data.put("key3", "data 3");  
  
FCMSend.Builder build = new FCMSend.Builder("<To Device Token>")
    .setTitle("<Title>") 
    .setBody("<Message>") 
    .setImage("<Image Url>") // Optional 
    .setClickAaction("<Click Aaction>") // Optional 
    .setData(data); // Optional
build.send();  

// KOTLIN  
val data = HashMap<String, String>() 
data["key1"] = "data 1" 
data["key2"] = "data 2" 
data["key3"] = "data 3"    

val build = FCMSend.Builder("<To Device Token>") 
    .setTitle("<Title>")  
    .setBody("<Message>") 
    .setImage("<Image Url>") // Optional 
    .setClickAaction("<Click Aaction>") // Optional 
    .setData(data) // Optional  
build.send()

Read Data

MainActivity

// JAVA
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        Bundle bundle = getIntent().getExtras();
        if (bundle != null) {
            String url = bundle.getString("url");
        }
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState) setContentView (R.layout.activity_kotlin_main)
      
        val bundle = intent.extras
        if (bundle != null) {
