iOS

Add ios/RNShimmer.xcodeproj to Libraries and add libRNShimmer.a to Link Binary With Libraries under Build Phases. More info and screenshots about how to do this is available in the React Native documentation.

Android

• Edit android/settings.gradle to look like this (without the +):

rootProject.name = 'MyApp'

include ':app'

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

• Edit android/app/build.gradle (note: app folder) to look like this:

apply plugin: 'com.android.application'

android {
  ...
}

dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile "com.android.support:appcompat-v7:23.0.1"
  compile "com.facebook.react:react-native:+"  // From node_modules
+ compile project(':react-native-shimmer')
}

• Edit your MainApplication.java (deep in android/app/src/main/java/...) to look like this (note two places to edit):

package com.myapp;

+ import com.oblador.shimmer.RNShimmerPackage;

....

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

}

Option: With CocoaPods

Add the following to your Podfile and run pod update:

pod 'react-native-shimmer', :path => 'node_modules/react-native-shimmer'

NOTE: Shimmer may only have one child.
