Where to Find Free Source Code

1. GitHub

Search for repositories using terms like “train schedule Android app free source code.” Many developers share their projects for free use or modification.
Example:

GitHub
Search for: “Android Train Schedule App Kotlin” or “Train Journey Planner Java”

2. Open-Source APIs

Google Transit API: Offers public transport schedules and route planning.
Railway-Specific APIs: Many rail operators provide APIs with live updates (e.g., Amtrak, Indian Railways).

3. Code Sharing Platforms

CodeCanyon: Sometimes provides free or discounted templates.
Open Source Projects: Look for platforms like SourceForge.

4. Developer Communities

Communities such as Stack Overflow and Reddit’s r/androiddev often share resources and ideas for open-source apps.

Steps to Build a Train Platform Android App

1. Set Up Development Tools

Use Android Studio as the Integrated Development Environment (IDE).
Develop with Kotlin (preferred) or Java.
Leverage APIs like Google Maps and Firebase for added functionality.

2. Develop Core Features

A. Train Schedule Screen
Use a RecyclerView to dynamically display train schedules.

class TrainScheduleAdapter(private val scheduleList: List<TrainSchedule>) :
    RecyclerView.Adapter<TrainScheduleAdapter.ScheduleViewHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ScheduleViewHolder {
        val itemView = LayoutInflater.from(parent.context)
            .inflate(R.layout.schedule_item, parent, false)
        return ScheduleViewHolder(itemView)
    }

    override fun onBindViewHolder(holder: ScheduleViewHolder, position: Int) {
        val schedule = scheduleList[position]
        holder.trainName.text = schedule.name
        holder.arrivalTime.text = schedule.arrivalTime
        holder.platform.text = "Platform: ${schedule.platform}"
    }

    override fun getItemCount() = scheduleList.size

    class ScheduleViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        val trainName: TextView = itemView.findViewById(R.id.train_name)
        val arrivalTime: TextView = itemView.findViewById(R.id.arrival_time)
        val platform: TextView = itemView.findViewById(R.id.platform)
    }
}

B. API Integration for Real-Time Updates
Fetch live data from train APIs using Retrofit.

interface TrainApiService {
    @GET("train-schedules")
    suspend fun getSchedules(): List<TrainSchedule>
}

C. Notifications
Send alerts using Firebase Cloud Messaging (FCM).

FirebaseMessaging.getInstance().subscribeToTopic("train_updates")
    .addOnCompleteListener { task ->
        if (task.isSuccessful) {
            Log.d("FCM", "Subscribed to train updates")
        }
    }

D. Map Integration
Use Google Maps API for station navigation and route planning.

3. Add Monetisation

Ads: Integrate Google AdMob for revenue.
In-App Purchases: Offer premium features like ad-free usage.

4. Testing and Deployment

Test across various Android devices to ensure compatibility.
Publish the app on the Google Play Store, ensuring compliance with guidelines.

FAQs

Q1: How can I source real-time train data?
Use APIs provided by railway operators or third-party transit APIs like Google Transit.

Q2: Is it necessary to use Kotlin?
While Kotlin is the recommended language for Android development, Java is still a viable alternative.

Q3: How can I integrate station maps?
Use Google Maps SDK or leverage station-specific APIs for detailed layouts.

Q4: Is offline functionality possible?
Yes, by caching schedule data and using local databases like Room.

Q5: How much does it cost to publish the app?
Google Play Store requires a one-time $25 (~£20) registration fee.
