#### Automatic installation

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

#### Manual installation

Android:

1. In your android/settings.gradle file, make the following additions:
``java
include ':react-native-splash-screen'
project(':react-native-splash-screen').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-splash-screen/android')
`

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

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

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

`java
// 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 getPackages() {
return Arrays.asList(
new MainReactPackage(),
new SplashScreenReactPackage() //here
);
}
};

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

iOS:

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-splash-screen and add SplashScreen.xcodeproj
3. In XCode, in the project navigator, select your project. Add libSplashScreen.a to your project's Build Phases ➜ Link Binary With Libraries

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

Android:

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

`java
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:


`obj-c

#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'

$3

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

android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/launch_screen">

`

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

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 true to the file. It should look like this:

`xml




`

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




`

$3

Customize your splash screen via LaunchImage or LaunchScreen.xib,

Usage

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

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();
}
}
``
