# Android Installation
First add `react-native-navigation` as an npm dependency: `yarn add react-native-navigation`

----

* Make sure you are using react-native version 0.43 or above
 
1.  Add the following to your `settings.gradle` file located in the `android` folder:

	```groovy
	include ':react-native-navigation'
	project(':react-native-navigation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-navigation/android/app/')
	```
	
2. Update project dependencies in `build.gradle` under `app` folder.
	```groovy
	android {
	    compileSdkVersion 25
	    buildToolsVersion "25.0.1"
	    ...
	}

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

3. Your `MainActivity` should extend `com.reactnativenavigation.controllers.SplashActivity` instead of `ReactActivity`. If you have any `react-native` related methods in your `MainActivity` you can safely delete them.

4. Update the MainApplication file and update the `Application` element in `AndroidManifest.xml`
	
	```java
	import com.reactnativenavigation.NavigationApplication;
	
	public class MainApplication extends NavigationApplication {
	
	}
	```
	
	```xml
	<application
        android:name=".MainApplication"
        ...
        />
	```
5. Implement `isDebug` and `createAdditionalReactPackages` methods

	```java
	import com.reactnativenavigation.NavigationApplication;
	
	public class MainApplication extends NavigationApplication {
 
    	@Override
		public boolean isDebug() {
			// Make sure you are using BuildConfig from your own application
			return BuildConfig.DEBUG;
		}

	    @Override
	    public List<ReactPackage> createAdditionalReactPackages() {
		// Add the packages you require here like so... (Tested on RN 0.42)
		return Arrays.<ReactPackage>asList(
           	    new <InsertPackageName()>;
       		);
		// No need to add RnnPackage and MainReactPackage
		// Simply return null if you do not have additional packages    
	        return null;
	    }
	}
	```
6. Run `react-native start`
