Splash-screen not work in react-native app on android

I have the react-native app and I need to implement a splash screen on android. My step was: put png images to app/src/main/res/mibmap, create background_splash.xml in app/src/main/res/drawable/, add SplashTheme to app/src/main/res/values/styles.xml, change AndroidManifest.xml, change MainActivity.java, create SplashActivity.java class in src/main/java/. But my splash screen is not appearing in the app. Can you explain to me please what I'm doing wrong?

Splash Screen drawable not found but Drawable clearly in project structure

I am trying to create a splash screen following this guide.
https://www.bignerdranch.com/blog/splash-screens-the-right-way/
I followed the steps line by line, however, I get an error saying the splash_background.xml isn't found.
Can anyone solve the problem? I really don't know what is wrong.

I think you should check carefully your code.
From your image, I am seeing you have: background_splash.xml
But your are getting the error:
I followed the steps line by line, however, I get an error saying the splash_background.xml isn't found.
Maybe you typed wrong name somewhere.

Looks like it should be background_splash.xml instead of splash_background.xml?

Try this man:
public class SplashActivity extends AppCompatActivity {
private static int SPLASH_TIME_OUT = 3000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent mainActivity = new Intent(SplashActivity.this, MainActivity.class);
startActivity(mainActivity);
finish();
}
}, SPLASH_TIME_OUT);
}
}

Application crashes upon new Activity

I know and I do understand that this question has been asked, but I can't seem to interpret it for my application. I am creating an application - using Android Studio - that opens a Activity (called 'About'). When a user clicks on the 'about button' on my MainActivity, it should launch the 'About' activity. However, when I test this out on my device, it says the app has stopped. And on my output panel, it says something about an error with my Manifest.xml file?
MainActivity:
package com.msp.supercarsounds;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void clickedAbout(View view) {
final int result = 1;
Intent AboutButtonClicked = new Intent (this, About.class);
AboutButtonClicked.putExtra("About", "MainActivity");
startActivityForResult(AboutButtonClicked, result);
}
}
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.msp.supercarsounds">
<uses-sdk android:minSdkVersion="17"

android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Thank you for your help and time!

You have to declare About activity
<activity android:name=".About">
</activity>
Add this below the </activity> tag of MainActivity

your second activity "about" is not added to manifest.xml add this under the mainactivity
<activity android:name=".about">/activity>

Android Hide Title Bar With Removing Appcompat Theme

ManinActivity.java
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
>
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#android:style/Theme.Light.NoTitleBar"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
I tried
requestWindowFeature(Window.FEATURE_NO_TITLE);
feature but it just won't work ! i don't able to find out why.
but when i use
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/Theme.AppCompat.NoActionBar">
it just worked !!! but i don't want to use Theme can i do it pragmatically ?

There are two ways to do that
Set below lines to your styles.xml
<item name="windowActionBar">false</item>
Or
Set below lines in your ActionBarActivity file.
getSupportActionBar().hide();

#Override
protected void onCreate(Bundle savedInstanceState) {
supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
}

Hide Action Bar for Splash Screen

I'm trying to create splash screen without action bar.
Firstly before created splash screen, action bar in main activity and when I create splash screen, action bar comes to splash screen and main activity is full screen. I searched method like getwindow(), getActionBar(), but when I use these method program says to me unfortunately stopped. So what I'm missing?
How can I avoid actionBar in splash screen?
My code:
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_item);
Thread th=new Thread(){
public void run(){
try {
sleep(4000);
Intent intent=new Intent(MainActivity.this,SplashScreen.class);
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}
finally{
finish();
}
}
};
th.start();
}
MANİFEST:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SplashScreen"
android:label="#string/app_name"
>
<intent-filter>
<action android:name="android.intent.action.SPLASHSCREEN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>

First, import the support library in the top of your app:
import android.support.v7.app.ActionBarActivity;
and change your code as follows:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_item);
getSupportActionBar().hide();
}

Using AppCompat for being supported for all versions:
<activity
android:theme="#style/Theme.AppCompat.Light.NoActionBar">

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
Put that before your setContentView(...), should get the job done.

For Android 3.0 or higher use ActionBarAPI#hide
For lower versions you will need to use Android Support Library.
Use ActionBar as
ActionBar actionBar = getSupportActionBar();
actionBar.hide();
Ref docs
Also if your requirement in static, then you can choose a theme for your activity that dos not have actionbar such as
android:theme="#android:style/Theme.Holo.Light.NoActionBar"
You can do this as:
<activity android:theme="#android:style/Theme.Holo.Light.NoActionBar"
android:name=".name_here"
android:label="#string/app_name" >

use a style without actionbar, also in your splash screen activity java extend Activity and make the splash screen your MAIN activity and in this activity you call an Intent to open your MainActivity after some seconds
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
</activity>
<activity android:theme="#android:style/Theme.Holo.Light.NoActionBar"
android:name=".SplashScreen"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Example:
In your SplashScreen activity write this code. This will open your MainActivity after 2 seconds.
new Handler().postDelayed(new Runnable()
{
public void run()
{
Intent localIntent = new Intent(SplashScreen.this, MainActivity.class);
SplashScreen.this.startActivity(localIntent);
SplashScreen.this.finish();
}
}, 2000L);

This is the simplest method.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
}
where R.layout.activity_main is replaced by your layout activity e.g. activity_splash
