# Integrate your app with Firebase Dynamic Links
​
Gamiphy ~~bot~~ **Loyalty app** uses ~~a~~ firebase dynamic ~~link~~**links** for deep linking.
~~creating and reciving deeplink will be throw Firebase Dynamic links, that~~ **This** is why you must integrate Firebase in your project.

~~At first, you should integrate your Android project with Firebase~~ **Please follow the documentation to integrate with Firebase**
[~~Follow~~ Firebase Docs](https://firebase.google.com/docs/android/setup)

​

# Set up Firebase Dynamic Links SDK
After making sure that your app connected ~~with~~ **to** your Firebase project, open [Firebase Console](https://console.firebase.google.com/u/0/). You will find a SHA-256 key ~~must~~ **that will** be specified ~~in firebase console~~ **to use** for Dynamic Links Functionality
> [It will be great if you can make the steps as bullets](/yFyDDA99QyqVVlrzg5wjzQ)

Add the dependency for the Firebase Dynamic Links Android library to your module ~~(app-level)~~ *`I didn't get that`* ~~Gradle file~~`not necessary` (usually app/`build.gradle`):

dependencies {  
  ...
  implementation 'com.google.firebase:firebase-dynamic-links:19.1.0'    
  implementation 'com.google.firebase:firebase-analytics:17.2.3'  
}

​
# Define your URL prefix `I think this should go before the previous step`
​
In the Firebase console, open the **Dynamic Links** section.

If you already have a Dynamic Links domain, take note of it. You need to provide a Dynamic Links domain when you programmatically create Dynamic Links.
you should save it under url_prefix in your Android Studio localization file. `You are trying to describe two scenarios here, right? If yes, then we need to make a better distinction between them.`
​
​
# Create a Dynamic Link
~~After Integrating Firebase/ Firebase dynamic link in your android project **app** then you can use Firebase SDK in your code. you should create the dynamic link.~~
**Now you can** use the following code to create a dynamic link:
​

dynamicLink = FirebaseDynamicLinks.getInstance().createDynamicLink()  
    .setLink(Uri.parse(getString(R.string.my_website_uri)))  
        .setDomainUriPrefix(getString(R.string.url_prefix))  
        // Open links with this app on Android  
        .setAndroidParameters(DynamicLink.AndroidParameters.Builder().build())  
        // Open links with com.example.ios on iOS  
        .setIosParameters(DynamicLink.IosParameters.Builder("com.example.ios").build())  
        .buildDynamicLink()  
  
val dynamicLinkUri = dynamicLink.uri

​
# Receive Firebase Dynamic Links parameter
`Can we use bullet points?`
​
### Add intent filter for deep links
​
**In order to handle the dynamic links** you ~~must~~ should add a new intent filter to the activity ~~that handles deep links for your app~~. The intent filter ~~should~~ **will** catch **the** deep links, **if exist** `not sure if that is alright`. ~~of your domain since the Dynamic Link will redirect to your domain if your app is installed~~. This is required for your app to receive the dynamic l
ink data after it is installed/updated from the Play Store ~~and one tap on Continue button~~ `I didn't get that one`. In `AndroidManifest.xml`
​

<intent-filter>  
 <action android:name="android.intent.action.VIEW" />  
 <category android:name="android.intent.category.DEFAULT" />  
 <category android:name="android.intent.category.BROWSABLE" />  
 <data  
	android:host="url_prefix"  
	android:scheme="https"/>
</intent-filter>

​
### Handle deep links
To receive the deep link, call the `getDynamicLink()` method:

 Firebase.dynamicLinks  
	 .getDynamicLink(intent)  
     .addOnSuccessListener(this) { pendingDynamicLinkData ->  
			  // Get deep link from result (may be null if no link is found)  
			  var deepLink: Uri? = null  
			  if (pendingDynamicLinkData != null) {  
	           deepLink = pendingDynamicLinkData.link  
	           referral = deeplink.getQueryParameter("referralId")   
	       }  
		 }  
	  .addOnFailureListener(this) { e -> Log.w(TAG, "getDynamicLink:onFailure", e) }

​
~~We need a referral to send it with Gamiphy’s bot URL.~~ `I don't get it`.
​
# Add parameter to the bot URL
​
Add ShareUrl and ~~referralId~~ **referrerId** to Gamiphy’s ~~bot~~ **app** url as query string
​
​

var builder: Uri.Builder = Uri.Builder().scheme("https")  
    .authority(getString(R.id.gamiphy_bot_url))  
    .appendQueryParameter("referralId", referral)  
    .appendQueryParameter("shareUrl", dynamicLink)  
  
var botUrl: Uri? = builder.build()

​
​
# Open ~~the bot~~ Gamiphy App
​
Insert these few lines in your onClickListener to open the ~~bot~~ app in your mobile browser.
​

val intent = Intent(Intent.ACTION_VIEW, botUrl)  
startActivity(intent)
