First I have Splash Screen for 3 secend and After that** I got a red Screen Error calling AppRegistry.runApplication in my mobile** and Can't See React Native Hello World

This is my MainActivity.java :

package com.mohajerkade;

import com.facebook.react.ReactActivity;

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 "Mohajerkade";
    }
}

and This is SplashActivity.java :

    package com.mohajerkade;

import com.facebook.react.ReactActivity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

public class SplashActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
        finish();
    }
}

I Used This Toturial But I Don't Know How Should I See Splash Screen In application loading and after that react native Hello World.

Answer 1

start it fresh, Lets go step by step.

• delete previous app from your phone
• start the server (react-native start)
• press run button from your android studio
• after that from your app open the developer's menu
• set your localhost(IP address:8081) by going to the option Debug server host for device.
• Reload and you are good to go.

Note:

If the phone is connected through USB then connect your system and phone with same wifi, else run adb reverse tcp:8081 tcp:8081

Cheers :)
