Wherro

License PRs Welcome

A module that helps in syncing locations

Wherro simplifies the location syncing to the server.

Apps using Wherro will run 2 services responsible for Location Syncing

Getting Started πŸ‘£

Wherro is distributed through Bintray. To use it you need to add the following Gradle dependency to your build.gradle file of your android app module (NOT the root file).

repositories {
    maven { url "https://jitpack.io" }
}
dependencies {
  implementation 'com.shuttl:locationsyncservice:0.2014'
}

To start using Wherro, just put in LocationConfigs through LocationsHelper.initLocationsModule method:

LocationsHelper.initLocationsModule(app = application, locationConfigs = LocationConfigs(), callback = callback, intent = intent)

Following need to be added in the app's AndroidManifest root

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Add this to your app's AndroidManifest application

        <service
            android:name="com.shuttl.location_pings.service.LocationPingService"
            android:foregroundServiceType="dataSync|location"
            android:stopWithTask="false" />
        <service
            android:name="com.shuttl.location_pings.service.LocationSaveService"
            android:foregroundServiceType="location|dataSync"
            android:stopWithTask="false" />

That's it! πŸŽ‰ Wherro will now start 2 services corresponding to Location Saving and Location Syncing simultaneously and show 1 notification for the same

Features 🧰

Don't forget to check the changelog to have a look at all the changes in the latest version of Wherro.

  • Compatible with OkHTTP 4 | Retrofit
  • API >= 16 compatible
  • Easy to integrate (just a 2 gradle implementation line)
  • Highly Configurable

Configure 🎨

data class LocationConfigs(
    val minTimeInterval: Int = 10000, // min Time Interval for Location Fetching
    val minDistanceInterval: Int = 100, // min Distance Interval for Location Fetching
    val minSyncInterval: Int = 10000, // min Time Interval for Location Syncing
    val accuracy: Int = 3, // accuracy of Lat-Long in meters, 3 means 110 meter
    val bufferSize: Int = 100, // number of entries at max can be stored in the Database
    val batchSize: Int = 10, // number of location entries sent at a time while polling
    val timeout: Int = 1800000, // time in milliseconds after which we stop the services
    val xApiKey: String? = "", // xApiKey Auth Key for the URL to function
    val syncUrl: String? = "", // PUTS the location parameters on this URL
    val wakeLock: Boolean? = true, // WakeLocks are enabled on service if made true
    val alarm: Boolean? = true, // Alarm Manager
    val canReuseLastLocation: Boolean? = true, // Last Location gets reused for the Sync on every interval, This will make sure that we ping every on every interval
    val smallIcon: Int = R.drawable.ic_loc // Notification icon
)

Callbacks

    private val callback = object : LocationPingServiceCallback<GPSLocation> {
        override fun afterSyncLocations(locations: List<GPSLocation>?) {
            Log.i(TAG, "afterSyncLocations, number of locations synced: " + locations?.size)
        }

        override fun errorWhileSyncLocations(error: Exception?) {
            Log.i(TAG, "errorWhileSyncLocations" + error?.toString())
        }

        override fun serviceStarted() {
            Log.i(TAG, "serviceStarted")
        }

        override fun serviceStopped() {
            Log.i(TAG, "serviceStopped")
        }

        override fun serviceStoppedManually() {
            Log.i(TAG, "serviceStoppedManually")
            LocationsHelper.stopAndClearAll(application)
        }

        override fun beforeSyncLocations(locations: List<GPSLocation>?, reused: Boolean): List<GPSLocation> {
            Log.i(TAG, "beforeSyncLocations, number of locations synced: " + locations?.size)
            return locations?: emptyList()
        }
    }

Request Body JSON in the PUT network call, along with xApiKey as Authorization

[
	{
	   //Its Configurable from beforeSyncLocations
	},
	{
	  //Its Configurable from beforeSyncLocations
	}
]

App runs an alarm that tries to restart service. Define you Reciever like this in AndroidManifest.xml

        <receiver
            android:name=".GPSRestartReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.USER_FOREGROUND" />
                <action android:name="android.intent.action.MY_PACKAGE_REPLACED" />
                <action android:name="android.intent.action.PHONE_STATE" />
                <action android:name="loc_save_alarm" />
                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </receiver>

Example of GPSRestartReciever

class GPSRestartReceiver : RestartReceiver() {

    override fun onReceivingAnEvent(context: Context?, intent: Intent?) {
        if (LocationsHelper.isServiceRunning(context, LocationSaveService::class.java) && LocationsHelper.isServiceRunning(context, LocationPingService::class.java)) {
            return
        }
        Toast.makeText(context, "Shuttl: Successfully Restarted", Toast.LENGTH_SHORT).show()
        val intent = Intent(context, LocationPingService::class.java)
        intent.action = "STOP"
        context?.let {
            LocationsHelper.initSilently(
                context = it.applicationContext, callback = callback, intent = intent
            )
        }
    }

    private val callback = object : LocationPingServiceCallback<GPSLocation> {
        override fun afterSyncLocations(locations: List<GPSLocation>?) {
        }

        override fun errorWhileSyncLocations(error: Exception?) {
        }

        override fun serviceStarted() {
        }

        override fun serviceStopped() {
        }

        override fun serviceStoppedManually() {
        }

        override fun beforeSyncLocations(locations: List<GPSLocation>?, reused: Boolean): List<GPSLocation> {
            return locations?: emptyList()
        }
    }
}

FAQ ❓

  • Why is it not working for me? - dependency issue maybe, create an issue if it doesn't work
  • Why is Notification not showing up for me? - some phones have an issue with running services, create an issue if you find such issues
