Deep Link Testing & Automation, Overall Deep Link Testing &…

- - - - Onelink click → Playstore → Install
      - App launch → Apps Flyer Sdk → AppsFlyer server → get Attribution & Deeplink data → callback to App
    - - Without App Install(Automated)
        
        AppsFlyer OneLink used for testing (https://click.pocketfm.in/whkH/76mqpvtc)
        
        On opening onelink, routes to playstore
        
        Click on install, side load PocketFM apk, click on open
        
        App is launched, do app validation with diff login methods
      - With App Install(Automated)
        
        On opening onelink, app is launched
        
        App is validated for auto-login & guest user cases
  - - - Facebook App → Facebook Ad Click → Play Store → Install → App launch → Appsflyer Sdk → FB server → Get Attribution and Deeplink Data → callback to App
    - - Without App Install(Manual)
        
        FB AD preview link(https://fb.me/adspreview/facebook/1M2MFNY7QdMPspP) used for testing
        
        An FB Ad preview link expires and must be generated again for each release testing
        
        On opening FB AD Preview link, takes to FB app, look for AD, click on it, routes to playstore
        
        Click on install, side load PocketFM apk, click on open
        
        App is launched, do app validation with diff login methods
      - With App Install(Manual)
        
        On opening FB Ad preview link, takes to FB app, look for AD, click on it, app is launched
        
        App is validated for auto-login & guest user cases
  - - - Google AD click → Play Store (with Install Referrer containing GCLID) →
      - Install → App launch → AppsFlyer SDK →
      - Reads Install Referrer via Google Play API →
      - Parses GCLID & deeplink → callback to App
    - - Install Referrer ONLY works with actual Play Store installations
      - Cannot test with sideloaded APKs (adb install)
      - Testing app cannot be published to Play Store without verification
    - - Without App Install(Manual simulation)
        
        Get device Advertising ID: adb shell settings get secure advertising_id
        
        Send test deeplink to Google server: curl "https://www.googleadservices.com/pagead/conversion/app/deeplink?&rdid=<DEVICE_ADID>&id_type=adid&bundleid=com.pocketfm.app&deeplink=pocketfm://episode/789&ddl_test=1"
        
        Enable debug mode: adb shell setprop debug.deferred.deeplink com.pocketfm.app
        
        Install PocketFM APK via sideload
        
        Launch app - AppsFlyer SDK will fetch test deeplink from Google
        
        App validation with different login methods
      - With App Install(Manual)
        
        Simulation: Not applicable (simulation only works for fresh installs)
        
        Alternative: Use direct deeplink testing adb shell am start -d "pocketfm://episode/789" com.pocketfm.app
    - - Google provides a test endpoint to simulate UAC deep linking without Play Store
      - 1) Retrieves unique device AD ID using "adb shell settings get secure advertising_id"
        
        Google uses this to identify which device should receive test deeplink
      - 2) Register Test Deep link using curl "https://www.googleadservices.com/pagead/conversion/app/deeplink?&rdid=<DEVICE_ADID>&id_type=adid&bundleid=com.pocketfm.app&deeplink=pocketfm://episode/789&ddl_test=1"
        
        What this does
        
        Tells Google server: Store this test deeplink for this device
        
        Deeplink stored for 24 hours on Google servers
      - 3) Enable Debug Mode using - adb shell setprop debug.deferred.deeplink com.pocketfm.app
        
        Purpose
        
        Enables Google Play Services to accept test deeplinks
        
        Without this, Play Services only accepts real campaign deeplinks
      - 4) How AppsFlyer SDK Works
        
        When app launches, AppsFlyer SDK tries multiple methods
        
        First attempt - Install Referrer API
        
        Checks if app was installed from Play Store
        
        In simulation, this returns NULL (sideloaded app)
        
        Second attempt - Google Analytics for Firebase (GA4F)
        
        AppsFlyer internally uses GA4F for deferred deeplinks
        
        Google returns the test deeplink we registered via curl
        
        AppsFlyer Parses attribution data & reads deeplink and returns to app
