At a Glance : Android Uninstall Tracking has become easier with Trackier MMP. The Trackier MMP gives you the option of tracking Android App Uninstalls in real-time, as another way to measure the quality of traffic and restrict frauds as well.
Setting up or enabling Android Uninstall Tracking is a simple three-step process and you can complete it on own following the simple steps mentioned below
1. Set Up A Common Identifier
Add the following code to Your Application to initiate setting up a common identifier.
private FirebaseAnalytics mFirebaseAnalytics;
FirebaseAnalytics mFirebaseAnalytics = FirebaseAnalytics.getInstance(this);
mFirebaseAnalytics.setUserProperty("ct_objectId", Objects.requireNonNull(TrackierSDK.getTrackierId())); |
Besides, setting up a common identifier, you can track the following fields while performing the uninstalls:
(optional) Application mode:
mFirebaseAnalytics.setUserProperty("ct_mode", Objects.requireNonNull("")); |
(optional) Customer user ID:
mFirebaseAnalytics.setUserProperty("ct_uid", Objects.requireNonNull("")); |
(optional) Customer email:
mFirebaseAnalytics.setUserProperty("ct_mail", Objects.requireNonNull("")); |
2. Set up conversion event using firebase
Though the firebase analytics automatically collects the app_remove event, still you will be required to enable that.
This is an Android-only event that is tracked when an application is uninstalled from the device.
Follow the below-mentioned steps to complete the set-up process:
Navigate to the firebase console and select the firebase project that is integrated with your android application.
Navigate to Analytics > Events in the Firebase Dashboard.
Enable the “Mark as conversion” toggle for the app_remove event.
3. Set up the cloud function to communicate uninstall data with Trackier
After the conversion is set up, use the cloud function for Firebase to create a function and send the uninstall data to Trackier MMP.
Pre-requisites:
Your system should have nodejs (https://nodejs.org/en/) installed, preferably version 18 or higher. Run the following command to check the installed nodejs version node -v.
Please make sure that your user in the application’s project on google cloud platform has the permission to create a cloud function here: https://console.cloud.google.com/functions/list
To create and publish a cloud function using Node JS, perform the following steps:
Open a terminal.
Set up Node.js and the Firebase CLI.
Run npm install -g firebase-tools.
To initialize Firebase SDK for Cloud Functions, run firebase login.
From your Firebase project directory, run firebase init functions.
Select Javascript as a language option.
Move to the functions directory, run cd functions.
Open index.js and add the following code:
// Import dependencies
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const axios = require("axios");
// Configure SDK Key here
const SDK_KEY = "";
// Initialize application via firebase admin
admin.initializeApp();
// Set function to exports
exports.sendAndroidUninstallToTrackierMMP = functions.analytics.event("app_remove").onLog((event) => {
// Extract values from user properties
const installId = (event.user.userProperties.ct_objectId) ? event.user.userProperties.ct_objectId.value : "";
const mode = (event.user.userProperties.ct_mode) ? event.user.userProperties.ct_mode.value : "";
const cuid = (event.user.userProperties.ct_uid) ? event.user.userProperties.ct_uid.value : "";
const cmail = (event.user.userProperties.ct_mail) ? event.user.userProperties.ct_mail.value : "";
// Prepare data for request
const url = "https://events.trackier.io/v1/uninstall";
const data = JSON.stringify({ installId, sdkKey: SDK_KEY, mode, cuid, cmail, meta: event });
// Send data back to Trackier MMP
axios.post(url, data, { headers: { "Content-Type": "application/json" } })
.then((response) => console.log(JSON.stringify({ installId, status: response.status, data: response.data })))
.catch((error) => console.error(JSON.stringify({ installId, status: error.response.status, data: error.response.data })));
}); |
Open package.json and add the following code:
{
"name": "functions",
"description": "Cloud Functions for Firebase",
"scripts": {
"lint": "eslint .",
"serve": "firebase emulators:start --only functions",
"shell": "firebase functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
"engines": {
"node": "18"
},
"main": "index.js",
"dependencies": {
"axios": "^0.24.0",
"firebase-admin": "^10.0.1",
"firebase-functions": "^3.16.0"
},
"devDependencies": {
"eslint": "^8.6.0",
"firebase-functions-test": "^0.3.3"
},
"private": true
} |
Open .eslintrc.js and add the following code, create one if does not exist:
module.exports = {
root: true,
env: {
es6: true,
node: true,
},
extends: [
"eslint:recommended",
],
rules: {
quotes: ["error", "double"]
},
}; |
Install all dependencies, run npm install.
Deploy the cloud function, run npm run deploy.
Once deployed, you can monitor the status of your cloud function here:
https://console.cloud.google.com/functions/list
