To receive the Firebase Dynamic Links that
you created, you must include the Dynamic Links SDK in your app and call the
FirebaseDynamicLinks.getDynamicLink()
method when your app loads to
get the data passed in the Dynamic Link.
Set up Firebase and the Dynamic Links SDK
If you haven't already, add Firebase to your Android project.
When you register your app, specify your SHA-1 signing key. If you use App Links, also specify your SHA-256 key.
-
In your module (app-level) Gradle file (usually
<project>/<app-module>/build.gradle.kts
or<project>/<app-module>/build.gradle
), add the dependency for the Dynamic Links Android library. We recommend using the Firebase Android BoM to control library versioning.For an optimal experience with Dynamic Links, we recommend enabling Google Analytics in your Firebase project and adding the Firebase SDK for Google Analytics to your app.
Kotlin+KTX
dependencies { // Import the BoM for the Firebase platform implementation(platform("com.google.firebase:firebase-bom:32.3.1")) // Add the dependencies for the Dynamic Links and Analytics libraries // When using the BoM, you don't specify versions in Firebase library dependencies implementation 'com.google.firebase:firebase-dynamic-links-ktx' implementation 'com.google.firebase:firebase-analytics-ktx' }
By using the Firebase Android BoM, your app will always use compatible versions of Firebase Android libraries.
(Alternative) Add Firebase library dependencies without using the BoM
If you choose not to use the Firebase BoM, you must specify each Firebase library version in its dependency line.
Note that if you use multiple Firebase libraries in your app, we strongly recommend using the BoM to manage library versions, which ensures that all versions are compatible.
dependencies { // Add the dependencies for the Dynamic Links and Analytics libraries // When NOT using the BoM, you must specify versions in Firebase library dependencies implementation 'com.google.firebase:firebase-dynamic-links-ktx:21.1.0' implementation 'com.google.firebase:firebase-analytics-ktx:21.3.0' }
Java
dependencies { // Import the BoM for the Firebase platform implementation(platform("com.google.firebase:firebase-bom:32.3.1")) // Add the dependencies for the Dynamic Links and Analytics libraries // When using the BoM, you don't specify versions in Firebase library dependencies implementation 'com.google.firebase:firebase-dynamic-links' implementation 'com.google.firebase:firebase-analytics' }
By using the Firebase Android BoM, your app will always use compatible versions of Firebase Android libraries.

- In the Firebase console, open the Dynamic Links section. Accept the terms of service if you are prompted to do so.
Add an intent filter for deep links
As with plain deep links, you must add a new intent filter to the activity that handles deep links for your app. The intent filter should catch deep links 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 Link data after it is installed/updated from the Play Store and one taps on Continue button. 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="example.com" android:scheme="https"/> </intent-filter>
When users open a Dynamic Link with a deep link to the scheme and host you specify, your app will start the activity with this intent filter to handle the link.
Handle deep links
To receive the deep link, call the
getDynamicLink()
method:Kotlin+KTX
Firebase.dynamicLinks .getDynamicLink(intent) .addOnSuccessListener(this) { pendingDynamicLinkData: PendingDynamicLinkData? -> // Get deep link from result (may be null if no link is found) var deepLink: Uri? = null if (pendingDynamicLinkData != null) { deepLink = pendingDynamicLinkData.link } // Handle the deep link. For example, open the linked // content, or apply promotional credit to the user's // account. // ... } .addOnFailureListener(this) { e -> Log.w(TAG, "getDynamicLink:onFailure", e) }
Java
FirebaseDynamicLinks.getInstance() .getDynamicLink(getIntent()) .addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() { @Override public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) { // Get deep link from result (may be null if no link is found) Uri deepLink = null; if (pendingDynamicLinkData != null) { deepLink = pendingDynamicLinkData.getLink(); } // Handle the deep link. For example, open the linked // content, or apply promotional credit to the user's // account. // ... // ... } }) .addOnFailureListener(this, new OnFailureListener() { @Override public void onFailure(@NonNull Exception e) { Log.w(TAG, "getDynamicLink:onFailure", e); } });
You must call
getDynamicLink()
in every activity that might be launched by the link, even though the link might be available from the intent usinggetIntent().getData()
. CallinggetDynamicLink()
retrieves the link and clears that data so it is only processed once by your app.You normally call
getDynamicLink()
in the main activity as well as any activities launched by intent filters that match the link.Record analytics
The following events can be automatically tracked in Google Analytics and shown in the Firebase console.
dynamic_link_app_open
dynamic_link_first_open
dynamic_link_app_update
In order to register these events, you need to configure Google Analytics before you retrieve the deep link. Check the following conditions are met:
- Call
FirebaseDynamicLinks.getDynamicLink()
in your app entry points: - Launcher activities. e.g.:
action="android.intent.action.MAIN"
,category="android.intent.category.LAUNCHER"
. - Activity entry points. e.g.:
onStart()
,onCreate()
. - Deep link activities.
- Set up and use Google Analytics:
- Include the Google Analytics dependency. This is usually automatically added by the
google-services
Gradle plugin. - Include the
google-services.json
config file in your app. - Call
FirebaseAnalytics.getInstance()
before callingFirebaseDynamicLinks.getDynamicLink()
.
Handling Dynamic Links using App Links
On Android 6.0 (API level 23) and higher, you can set up your app to handle Dynamic Links directly when your app is already installed by using Android App Links.
Ensure that you have added the SHA256 certificate fingerprint for your app into your project in the Firebase console. Dynamic Links will handle setting up the App Links website association for your Dynamic Links domain.
Add an auto-verified intent filter to the Activity that will handle the Dynamic Link, setting the host to your project's Dynamic Links domain as found in the Firebase console. In the
AndroidManifest.xml
:<intent-filter android:autoVerify="true"> <action android:name="android.intent.action.VIEW"/> <category android:name="android.intent.category.DEFAULT"/> <category android:name="android.intent.category.BROWSABLE"/> <data android:host="example.com/link" android:scheme="http"/> <data android:host="example.com/link" android:scheme="https"/> </intent-filter>
Note that the
android:host
must be set to your Dynamic Links domain, and not the domain of your deep link.All
autoVerify
intent filters in your manifest must be registered in order for App Links to engage. Firebase handles this automatically for your Dynamic Links domains, but you can check this by opening theassetlinks.json
file hosted on your Dynamic Links domain:https://YOUR_DOMAIN/.well-known/assetlinks.json
All of your Firebase apps' package names should be included.Dynamic Links will now be sent directly to your app. You will be able to get the deep link and other Dynamic Link data by calling
getDynamicLink()
in the Activity you added the App Links intent filter to (as described in Handle deep links).Note: Since invoking through App Links takes the user directly to the app, a Dynamic Link cannot honor the required minimum version. So once the app is opened, you need to compare the Dynamic Link's minimum version ( getminimumappversion) against PackageInfo.versionCode and redirect the user to upgrade the app if required using getUpdateAppIntent.
