question: For capacitor 3.0 do we need to edit MainActivity.java?

[mesqueeb]

The README still says:

on your MainActivity.java file add import com.getcapacitor.community.fcm.FCMPlugin; and then inside the init callback add(FCMPlugin.class);

But is this only for Capacitor 2.x? Or also required for Capacitor 3.x?

[stewones]

on Capacitor v3 plugins are loaded automatically (as long as they aren't built specifically for your application). For community plugins you can remove it safely.

 public class MainActivity extends BridgeActivity {
-    @Override
-    public void onCreate(Bundle savedInstanceState) {
-        super.onCreate(savedInstanceState);
-
-        // Initializes the Bridge
-        this.init(savedInstanceState, new ArrayList<Class<? extends Plugin>>() {{
-            // Additional plugins you've installed go here
-            add(Plugin1.class);
-            add(Plugin2.class);
-        }});
-    }
 }
