Linkt

A lightweight and simple kotlin library for deep link handling on Android.

Setup

Configure root build.gradle (jitpack.io):

allprojects {  
    repositories {  
        ...  
        maven { url 'https://jitpack.io' }  
    }  
}

Add Linkt to your project build.gradle:

dependencies {
  implementation 'com.github.jeziellago:Linkt:TAG'
}

Create your DeepLinkModule and register deep links:

class MyDeepLinkModule : DeepLinkModule {

    override fun load() {
        deepLinkOf(
            "linkt://sample",
            "linkt://sample/{userId}/{userName}"
        ) { context, bundle ->
            Intent(context, MainActivity::class.java)
                .apply { putExtras(bundle) }
        }
    }
}

In multi-module projects you should have one or more DeepLinkModule`s.

class MyApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        DeepLinkLoader.setup(MyDeepLinkModule())
    }
}

Create the DeepLinkActivity (or use yours if already exists), and call DeepLinkLoader#loadFrom:

class DeepLinkActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        // resolve deeplink
        DeepLinkLoader.loadFrom(this)
    }
}

Don't forget to configure AndroidManifest.xml (required for Android deep links):

<activity
    android:name="org.linkt.DeepLinkActivity"
    android:theme="@android:style/Theme.NoDisplay">
    <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:scheme="mycompany" />
    </intent-filter>
</activity>

How to get data from deeplink?

In your activity, you can get path parameters and query values as String from intent.extras:

Path parameters

Template linkt://sample/{userId}/{userName}
Received: linkt://sample/9999/Jose

// get path parameters
val userId = intent.extras.getString("userId")
val userId = intent.extras.getString("userName")

Query parameters

Template: linkt://sample
Received linkt://sample?subject=Linkt&name=Sample

// get query parameters
val subject = intent.extras.getString("subject")
val name = intent.extras.getString("name")

Path + query parameters

Template linkt://sample/{userId}/{userName}
Received linkt://sample/999/Jose?subject=Linkt&name=Sample

// get path parameters
val userId = intent.extras.getString("userId")
val userId = intent.extras.getString("userName")
// get query parameters
val subject = intent.extras.getString("subject")
val name = intent.extras.getString("name")
