      SplashScreen.show(this);
  
     ...my other codes

      super.onCreate(null);
// super.onCreate(savedInstanceState); <- this also tried but not working
    }

I don’t know why I’m having this kind of error. because of React Native 0.7 version error? or what,please help…

@bonusrk I followed your guide, but mine doesn’t work.

package com.myapp.com.myapp;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

import com.facebook.react.ReactActivity;
import org.devio.rn.splashscreen.SplashScreen;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.lockincomp.liappagent.LiappAgent;

public class MainActivity extends ReactActivity {

  /**
   * Returns the name of the main component registered from JavaScript. This is used to schedule
   * rendering of the component.
   */
  @Override
  protected String getMainComponentName() {
    return "MyApp";
  }

  /**
   * Returns the instance of the {@link ReactActivityDelegate}. There the RootView is created and
   * you can specify the renderer you wish to use - the new renderer (Fabric) or the old renderer
   * (Paper).
   */

  @Override.    //<-------here is I added onCreate upper side but still doesn't work...is that right way I did?
  protected void onCreate(Bundle savedInstanceState) {
    SplashScreen.show(this);
    super.onCreate(null);
  }


  @Override
  protected ReactActivityDelegate createReactActivityDelegate() {
    return new MainActivityDelegate(this, getMainComponentName());
  }

  public static class MainActivityDelegate extends ReactActivityDelegate {
    public MainActivityDelegate(ReactActivity activity, String mainComponentName) {
      super(activity, mainComponentName);
    }

    @Override
    protected ReactRootView createRootView() {
      ReactRootView reactRootView = new ReactRootView(getContext());
      // If you opted-in for the New Architecture, we enable the Fabric Renderer.
      reactRootView.setIsFabric(BuildConfig.IS_NEW_ARCHITECTURE_ENABLED);
      return reactRootView;
    }

    @Override
    protected boolean isConcurrentRootEnabled() {
      // If you opted-in for the New Architecture, we enable Concurrent Root (i.e. React 18).
      // More on this on https://reactjs.org/blog/2022/03/29/react-v18.html
      return BuildConfig.IS_NEW_ARCHITECTURE_ENABLED;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {

      ...my other codes which supposed to in this area
      super.onCreate(null);
    }
  }
}

I think you should move onCreate totally. I mean delete it in nested class and keep only in top level. I went event a little bit forward and kept only main class just to check and it works

package com.myapp;

import android.os.Bundle;
import com.facebook.react.ReactActivity;
import org.devio.rn.splashscreen.SplashScreen;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;

public class MainActivity extends ReactActivity {

  /**
   * Returns the name of the main component registered from JavaScript. This is used to schedule
   * rendering of the component.
   */
  @Override
  protected String getMainComponentName() {
    return "MyApp";
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    SplashScreen.show(this);
    super.onCreate(null);
  }
}

Fresh RN application MainActivity.java looks like so now:

package com.myapp;

import android.os.Bundle;
import com.facebook.react.ReactActivity;
import org.devio.rn.splashscreen.SplashScreen;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;

public class MainActivity extends ReactActivity {

  /**
   * Returns the name of the main component registered from JavaScript. This is used to schedule
   * rendering of the component.
   */
  @Override
  protected String getMainComponentName() {
    return "MyApp";
  }

  /**
   * Returns the instance of the {@link ReactActivityDelegate}. There the RootView is created and
   * you can specify the renderer you wish to use - the new renderer (Fabric) or the old renderer
   * (Paper).
   */
  @Override
  protected ReactActivityDelegate createReactActivityDelegate() {
    return new MainActivityDelegate(this, getMainComponentName());
  }

  public static class MainActivityDelegate extends ReactActivityDelegate {
    public MainActivityDelegate(ReactActivity activity, String mainComponentName) {
      super(activity, mainComponentName);
    }

    @Override
    protected ReactRootView createRootView() {
      ReactRootView reactRootView = new ReactRootView(getContext());
      // If you opted-in for the New Architecture, we enable the Fabric Renderer.
      reactRootView.setIsFabric(BuildConfig.IS_NEW_ARCHITECTURE_ENABLED);
      return reactRootView;
    }

    @Override
    protected boolean isConcurrentRootEnabled() {
      // If you opted-in for the New Architecture, we enable Concurrent Root (i.e. React 18).
      // More on this on https://reactjs.org/blog/2022/03/29/react-v18.html
      return BuildConfig.IS_NEW_ARCHITECTURE_ENABLED;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
      SplashScreen.show(this);
      super.onCreate(null);
    }
  }
}

Still have the issue incompatible types: MainActivityDelegate cannot be converted to Activity SplashScreen.show(this);

method show goes from here

    /**
     * 打开启动屏
     */
    public static void show(final Activity activity) {
        show(activity, false);
    }

and it take Activity type, while this in MainActivity is MainActivityDelegate

If we move onCreate outside of MainActivityDelegate to the very top class application will be built successfully
