Locationmanager

Locationmanager is a small wrapper for Location Tracker.

Installation

  • Add jitpackto your repositories in Project build.gradle :
allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
    ...
}
  • Add dependency :
implementation 'com.github.grumpyshoe:android-module-locationmanager:1.3.0'

Usage

  • Get instance of LocationManager:
val locationManager : LocationManager = LocationManagerImpl()

In order to locate your device, the library will request the permissions android.permission.ACCESS_FINE_LOCATION and android.permission.ACCESS_COARSE_LOCATION. To handle to permission request result correctly delegate the response of onRequestPermissionsResult in your activity to the library like this:

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
    locationManager.onRequestPermissionsResult(requestCode, permissions, grantResults)
            ?: super.onRequestPermissionsResult(requestCode, permissions, grantResults)
}

Also it's necessary to delegate the response of 'ònActivityResult`to your LocationManager instance

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        locationManager.onActivityResult(requestCode, resultCode, data)
            ?: super.onActivityResult(requestCode, resultCode, data)
}

Get last known Location

Try to get last known connection with getLastKnownLocation.

locationManager.getLastKnownLocation(activity = this).observe(
      this,
      Observer<Location?> { location ->
          // handle location data
      })

Track location

If you want continuous information about device movement start the location tracking.

Start location tracking

To start location tracking call startLocationTracker.

locationManager.startLocationTracker(
    activity = this, config = LocationTrackerConfig()
).observe(
    this,
    Observer<Location?> { location ->
        // handle location data
    })

Stop location tracking

To stop location tracking call stopLocationTracker. This should be done at LifeCycleEvent onDestroy at least to avoid any error during off screen information.

locationManager.stopLocationTracker()

Customization

If the Permission is granted but the location provider is disabled a AlertDialog is shown. The options are 'Cancel' and 'Settings' to enable the Location Service again.

For customizing the text that is shown at the AlertDialog the following string resources must be overridden at you app:

  • R.string.locationmanager_gps_network_not_enabled (default: "Location Provider is not enabled. This Service is required otherwise no results will be posted.")
  • R.string.locationmanager_open_location_settings (default: "Settings")
  • R.string.locationmanager_btn_cancel (default: "Cancel")
