Examples

Installation

First step(Download):

Run npm i react-native-splash-screen --save

Second step(Plugin Installation):

Automatic installation

react-native link react-native-splash-screen or rnpm link react-native-splash-screen

Manual installation

Android:

In your android/settings.gradle file, make the following additions:

include ':react-native-splash-screen'   
project(':react-native-splash-screen').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-splash-screen/android')

In your android/app/build.gradle file, add the :react-native-splash-screen project as a compile-time dependency:

...
dependencies {
    ...
    compile project(':react-native-splash-screen')
}

Update the MainApplication.java file to use react-native-splash-screen via the following changes:

// react-native-splash-screen >= 0.3.1
import org.devio.rn.splashscreen.SplashScreenReactPackage;
// react-native-splash-screen < 0.3.1
import com.cboy.rn.splashscreen.SplashScreenReactPackage;

public class MainApplication extends Application implements ReactApplication {

    private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
        @Override
        protected boolean getUseDeveloperSupport() {
            return BuildConfig.DEBUG;
        }

        @Override
        protected List<ReactPackage> getPackages() {
            return Arrays.<ReactPackage>asList(
                    new MainReactPackage(),
            new SplashScreenReactPackage()  //here
            );
        }
    };

    @Override
    public ReactNativeHost getReactNativeHost() {
        return mReactNativeHost;
    }
}

iOS:

In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
Go to node_modules ➜ react-native-splash-screen and add SplashScreen.xcodeproj
In XCode, in the project navigator, select your project. Add libSplashScreen.a to your project's Build Phases ➜ Link Binary With Libraries
To fix 'SplashScreen.h' file not found, you have to select your project → Build Settings → Search Paths → Header Search Paths to add:

$(SRCROOT)/../node_modules/react-native-splash-screen/ios

Third step(Plugin Configuration):

Android:

Update the MainActivity.java to use react-native-splash-screen via the following changes:

import android.os.Bundle; // here
import com.facebook.react.ReactActivity;
// react-native-splash-screen >= 0.3.1
import org.devio.rn.splashscreen.SplashScreen; // here
// react-native-splash-screen < 0.3.1
import com.cboy.rn.splashscreen.SplashScreen; // here

public class MainActivity extends ReactActivity {
   @Override
    protected void onCreate(Bundle savedInstanceState) {
        SplashScreen.show(this);  // here
        super.onCreate(savedInstanceState);
    }
    // ...other code
}

iOS:

Update AppDelegate.m with the following additions:

#import "AppDelegate.h"
#import "RCTRootView.h"
#import "SplashScreen.h"  // here

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // ...other code

    [SplashScreen show];  // here
    return YES;
}

@end

Getting started

Import react-native-splash-screen in your JS file.

import SplashScreen from 'react-native-splash-screen'

Android:

Create a file called launch_screen.xml in app/src/main/res/layout (create the layout-folder if it doesn't exist). The contents of the file should be the following:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/launch_screen">
</LinearLayout>

Customize your launch screen by creating a launch_screen.png-file and placing it in an appropriate drawable-folder. Android automatically scales drawable, so you do not necessarily need to provide images for all phone densities. You can create splash screens in the following folders:

drawable-ldpi
drawable-mdpi
drawable-hdpi
drawable-xhdpi
drawable-xxhdpi
drawable-xxxhdpi

To modify the status bar color, you can add a color called primary_dark in color.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="primary_dark">#000000</color>
</resources>

Optional steps：

If you want the splash screen to be transparent, follow these steps.

Open android/app/src/main/res/values/styles.xml and add <item name="android:windowIsTranslucent">true</item> to the file. It should look like this:

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <!--设置透明背景-->
        <item name="android:windowIsTranslucent">true</item>
    </style>
</resources>

To learn more see examples

If you want to customize the color of the status bar when the splash screen is displayed:

Create android/app/src/main/res/values/colors.xml and add

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="status_bar_color"><!-- Colour of your status bar here --></color>
</resources>

Create a style definition for this in android/app/src/main/res/values/colors.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="SplashScreenTheme" parent="SplashScreen_SplashTheme">
        <item name="colorPrimaryDark">@color/status_bar_color</item>
    </style>
</resources>

Change your show method to include your custom style:

SplashScreen.show(this, false, R.style.SplashScreenTheme);

iOS

Customize your splash screen via LaunchImage or LaunchScreen.xib,

export default class WelcomePage extends Component {

    componentDidMount() {
    	// do stuff while splash screen is shown
        // After having done stuff (such as async tasks) hide the splash screen
        SplashScreen.hide();
    }
}
