 1 | Location Tracker App
 2 | 
 3 | This project demonstrates a basic Android application that tracks a user's location, integrates with Firebase, and provides notifications using a BroadcastReceiver. It includes Google Maps integration using the Google Cloud Platform API.
 4 | 
 5 | Features
 6 | Real-time location tracking.
 7 | Google Maps integration.
 8 | Firebase integration.
 9 | Push notifications using BroadcastReceiver.
10 | Background services to track location updates.
11 | Step-by-Step Implementation Guide
12 | 1. Add Dependency in Gradle
13 | Open your build.gradle (Module) file and add the following dependencies:
14 | 
15 | Sync your project after adding the dependencies.
16 | 
17 | 2. Design Main Activity
18 | In your MainActivity.java, design the UI to include a button to launch the MapsActivity. You can create a simple layout with a button using XML:
19 | 
20 | 
21 | <Button
22 |     android:id="@+id/btnStartTracking"
23 |     android:layout_width="wrap_content"
24 |     android:layout_height="wrap_content"
25 |     android:text="Start Tracking" />
26 | Set up an OnClickListener in MainActivity to start the MapsActivity.
27 | 
28 | 3. Create MapsActivity from Template
29 | Create a new MapsActivity from the Google Maps Activity template. To do this:
30 | 
31 | Right-click on your package in Android Studio.
32 | Select New -> Google -> Google Maps Activity.
33 | This will automatically generate MapsActivity.java and activity_maps.xml, along with the necessary configuration in AndroidManifest.xml.
34 | 4. Create Location Service
35 | To track the user’s location, create a background service called LocationService:
36 | 
37 | Create a new class LocationService.java.
38 | Use FusedLocationProviderClient to fetch the current location.
39 | 
40 | 5. Connect Account with Firebase
41 | Follow these steps to connect Firebase to your project:
42 | 
43 | Go to the Firebase Console.
44 | Create a new Firebase project and register your Android app.
45 | Download the google-services.json file and place it in the app/ directory.
46 | Add the Firebase SDK by modifying your project-level build.gradle:
47 | 
48 | 6. Create Google Cloud Platform Project for API Key
49 | Go to the Google Cloud Console.
50 | Create a new project and enable the Maps SDK for Android.
51 | Generate an API key and restrict it to your app’s package name.
52 | Add the API key to your AndroidManifest.xml:
53 | 
54 | 7. Create Broadcast Receiver and Application-Level Class for Notifications
55 | Create a BroadcastReceiver to handle notifications:
56 | 
57 | 
58 | To set up application-wide notification handling, create an Application class:
59 | 
60 | In MyApplication.java:
61 | 
62 | Update the AndroidManifest.xml to declare the Application and BroadcastReceiver.
63 | 
64 | 
65 | <application
