MMA is the project for this purpose. When a user performs a certain +UI action, he/she will see a prompt and have a chance to interact with it. For example, if a user uses +Firefox 10 times a week, but Firefox is not his default browser, we'll prompt the user the next time +when he launchers our app, and guide him to set us as default browser. + +Mozilla is using a third party framework called "Leanplum" in order to achieve above goal for +Android 56 release. Leanplum is a San Francisco company, founded in 2012. We put their SDK in +our codebase and sync upstream when there's a major update. Please find it in ``mobile/android/thirdparty/com/leanplum``. +The SDK is documented at https://www.leanplum.com/docs/android/ + +There are three major component in Leanplum SDK. +1. Events : Triggers when users perform certain actions. An event will normally trigger a prompt message. +2. Deep Links : Actions that users can perform to interact with the prompt message. +3. Messages : Campaigns that we want to engage with users. Messages is a combination of an Event and a Deep Link. + +Data collection +~~~~~~~~~~~~~~~ + +Who will have Leanplum enabled? +====================================================== + +* We use Switchboard https://wiki.mozilla.org/Firefox/Kinto to filter users to have Leanplum enabled. Currently, for users in the USA + and whose locale is set to English, 10% of that users will have Leanplum enabled. +* If the user has "Health Report" setting enabled. +* If above two are true, when the app starts, and switchboard configure arrived, Firefox for Android will send the + triggers and message interaction history to Leanplum server when available. + + +Where does data sent to the Leanplum backend go? +====================================================== + +The Leanplum SDK is hard-coded to send data to the endpoint https://www.leanplum.com. The endpoint is +defined by ``com.leanplum.internal.Constants.API_HOST_NAME`` at +https://searchfox.org/mozilla-central/rev/c49a70b53f67dd5550eec8a08793805f2aca8d42/mobile/android/thirdparty/com/leanplum/internal/Constants.java#32. + +The user is identified by Leanplum using a random UUID generated by Firefox for Android when Leanplum is initialized for the first time. +This unique identifier is only used by Leanplum and can't be tracked back to any Firefox users. + + +What data is collected and sent to the Leanplum backend? +========================================================== + +The Leanplum SDK collects and sends two messages to the Leanplum backend. The messages have the +following parameters:: + + // Sent every time when an event is triggered + "action" -> "track" // track: an event is tracked. + "event" -> "Launch" // Used when an event is triggered. e.g. E_Saved_Bookmark. + "info" -> "" // Used when an event is triggered.

This happens separately when Leanplum SDK gets initialized. + +Notes on what data is collected +------------------------------- + +User Identifier: +Since Device ID is a random UUID, Leanplum can't map the device to any know Client ID in Firefox for Android nor Advertising ID. + +Events: +Most of the Leanplum events can be mapped to a single combination of Telemetry event (Event+Method+Extra). +Some events are not collected in Mozilla Telemetry. This will be addressed separately in each campaign review. +There are three elements that are used for each event. They are: event name, value(default: 0.0), and info(default: ""). +Default value for event value is 0.0. Default value for event info is empty string. + +List of current Events related data that is sent: + +* When a page could be reader mode and is visible to the user + +.. code-block:: json + + { + "event": "E_Reader_Available" + } + +* Download videos or any other media + +.. code-block:: json + + { + "event" : "E_Download_Media_Saved_Image" + } + +* Save password and login from door hanger + +.. code-block:: json + + { + "event" : "E_Saved_Login_And_Password" + } + +* Save a bookmark from Firefox for Android menu + +.. code-block:: json + + { + "event" : "E_Saved_Bookmark" + } + +* Load the bookmark from home panel + +.. code-block:: json + + { + "event" : "E_Opened_Bookmark" + } + +* Interact with search url area + +.. code-block:: json + + { + "event" : "E_Interact_With_Search_URL_Area" + } + +* Interact with search widget + +.. code-block:: json + + { + "event" : "E_Interact_With_Search_Widget" + } + +* When a screenshot is taken + +.. code-block:: json + + { + "event" : "E_Screenshot" + } + +* Open a new tab + +.. code-block:: json + + { + "event" : "E_Opened_New_Tab" + } + +* App start but Firefox for Android is not set as default browser + +.. code-block:: json + + { + "event" : "E_Launch_But_Not_Default_Browser" + } + +* General app start event + +.. code-block:: json + + { + "event" : "E_Launch_Browser" + } + +* The user just dismissed on-boarding + +.. code-block:: json + + { + "event" : "E_Dismiss_Onboarding" + } + +* Sign in Firefox Account + +.. code-block:: json + + { + "event" : "E_User_Signed_In_To_FxA" + } + +* Firefox Sync finished event + +.. code-block:: json + + { + "event" : "E_User_Finished_Sync" + } + +* The user just resumed the app from background + +.. code-block:: json + + { + "event" : "E_Resumed_From_Background" + } + +* User set Firefox for Android as default browser and resumed the app + +.. code-block:: json + + { + "event" : "E_Changed_Default_To_Fennec" + } + +* User installed the Focus app + +.. code-block:: json + + { + "event" : "E_Just_Installed_Focus" + } + +* User installed the Klar app + +.. code-block:: json + + { + "event" : "E_Just_Installed_Klar" + } + +* User accessed the promo webpage for the Awesomescreen's Firefox promo banner. + +.. code-block:: json + + { + "event" : "E_Opened_Firefox_Promo" + } + +* User dismissed the Awesomescreen's Firefox promo banner. + +.. code-block:: json + + { + "event" : "E_Dismissed_Firefox_Promo" + } + +Deep Links: +Deep links are actions that can point Firefox for Android to open certain pages or load features such as `show bookmark list` or +`open a SUMO page`. When users see a prompt Leanplum message, they can click the button(s) on it. These buttons can +trigger the following deep links: + +* Link to open pages specifically in Firefox for Android (firefox://open?url=) +* Link to Set Default Browser settings (firefox://default_browser) +* Link to specific Add-on page (http://link_to_the_add_on_page) +* Link to sync signup/sign in (firefox://sign_up) +* Link to default search engine settings (firefox://preferences_search) +* Link to “Save as PDF” feature (firefox://save_as_pdf) +* Take user directly to a Sign up for a newsletter (http://link_to_newsletter_page) +* Link to bookmark list (firefox://bookmark_list) +* Link to history list (firefox://history_list) +* Link to main preferences (firefox://preferences) +* Link to privacy preferences (firefox://preferences_privacy) +* Link to notifications preferences (firefox://preferences_notifications) +* Link to accessibility preferences (firefox://preferences_accessibility) +* Link to general setting (firefox://preferences_general) +* Link to home page setting (firefox://preferences_home) + +Messages : +Messages are prompts to the user from Leanplum. Messages can be in-app prompts or push notifications. The interaction of that prompt will be kept and sent to Leanplum backend (such +as "Accept" and "Show"). A messages is a combination of an Event and a Deep Link. The combinations are downloaded from Leanplum +when Leanplum SDK is initialized. When the criteria is met (set in Leanplum backend, could be when an event happens a certain number of times, +and/or targeting certain user attribute ), a prompt message will show up. And there may be buttons for users to click. Those clicks +may trigger deep links. + +We use another Mozilla's Google Cloud Messaging(GCM) sender ID to send push notifications. +These push notifications will look like the notifications that Sync sends out. +Sender ID let GCM knows Mozilla is sending push notifications via Leanplum. +GCM will generate a token at client side. We'll send this GCM token to Leanplum so Leanplum knows whom to send push notifications. +This token is only useful to Mozilla's sender ID so it's anonymized to other parties. +Push Notifications can be triggered by Events, or be sent by Mozilla marketing team manually. + +The list of current messages for Android can be found here: https://wiki.mozilla.org/Leanplum_Contextual_Hints#Android + +Technical notes +~~~~~~~~~~~~~~~ + +Build flags controlling the Leanplum SDK integration +====================================================== + +To test this locally, add lines like: + +export MOZ_ANDROID_MMA=1 +ac_add_options --with-leanplum-sdk-keyfile=/path/to/leanplum-sdk-developer.token + +MOZ_ANDROID_MMA depends on MOZ_ANDROID_GOOGLE_PLAY_SERVICES and MOZ_ANDROID_GCM. +Since Leanplum requires Google Play Services library, those flags are a proxy for it, and enable respectively. + +We want to enable MOZ_ANDROID_MMA in Nightly, but only for +MOZILLA_OFFICIAL builds. Since MOZILLA_OFFICIAL is still defined in +old-configure.in, we can't integrate it in +mobile/android/moz.configure, and therefore we enable using the +automation mozconfigs. + +Technical notes on the Leanplum SDK integration +================================================ + +Just like Adjust, MmaDelegate uses mmaInterface to inject the MmaLeanplumImp and MmaStubImp. +Constants used by Leanplum is in MmaConstants. Services in AndroidManifest are in +``mobile/android/base/MmaAndroidManifest_services.xml.in`` which is also injected by build flag +MOZ_ANDROID_MMA. + +Notes and links +================= + +* Leanplum web page: http://leanplum.com/ +* Leanplum SDK github repo: https://github.com/Leanplum/Leanplum-Android-SDK |
