Following FetchAddressIntentService implementation with IntentService (in kotlin):
class FetchAddressIntentService //Constructor of this service
: IntentService(INTENTTAG) {
//Receiver where results are forwarded from this service
protected var resultReceiver: ResultReceiver? = null
private val TAG by lazy { this::class.java.simpleName }
//Intent Service handler
override fun onHandleIntent(intent: Intent?) { //Errormessages
var errorMessage = ""
if (intent != null) {
resultReceiver =
intent.getParcelableExtra(RECEIVER)
}
//Checks if receiver was properly registered
if (resultReceiver == null) {
Log.wtf(
TAG,
"No reciever received. There is nowhere to send the results !!"
)
return
}
//Get the location passed to this service through an extra.
var location: Location? = null
if (intent != null) {
location =
intent.getParcelableExtra(LOCATION_DATA_EXTRA)
}
//Make sure the location is really sent
if (location == null) {
errorMessage = getString(R.string.gis_error_no_location_data_provided)
Log.wtf(TAG, errorMessage)
deliverResultToReceiver(FAILURE_RESULT, errorMessage)
return
}
//Setting locale
val geocoder = Geocoder(this, Locale.ROOT)
//Address found
var addresses: List<Address>? = null
try {
addresses = geocoder.getFromLocation(location.latitude, location.longitude, 1)
Log.i(TAG,"rec: address = ${addresses[0]}")
} catch (ioException: IOException) { //Catches network or i/o problems
errorMessage = getString(R.string.gis_error_service_not_available)
Log.e(TAG, errorMessage, ioException)
} catch (illegalArgumentException: IllegalArgumentException) { //Error in latitude or longitude data
errorMessage = getString(R.string.gis_error_invalid_lat_long_used)
Log.e(
TAG,
errorMessage + ". Latitude = " + location.latitude +
", Longitude = " + location.longitude,
illegalArgumentException
)
}
//Handles cases where no addresses where found
if (addresses == null || addresses.isEmpty()) {
if (errorMessage.isEmpty()) {
errorMessage = getString(R.string.gis_error_no_address_found)
Log.e(TAG, errorMessage)
}
deliverResultToReceiver(FAILURE_RESULT, errorMessage)
} else {
val address = addresses[0]
//deliverAddressToReceiver(SUCCESS_RESULT, address)
deliverAddressToReceiver2(SUCCESS_ADDRESS,address)
}
}
private fun deliverAddressToReceiver2(
resultCode: Int,
address: Address
){
val bundle = Bundle()
bundle.putParcelable("address",address)
resultReceiver?.send(resultCode,bundle)
}
private fun deliverResultToReceiver(resultCode: Int, message: String) {
val bundle = Bundle()
bundle.putString(RESULT_DATA_KEY, message)
resultReceiver!!.send(resultCode, bundle)
}
companion object {
private const val INTENTTAG = "FetchAddressIS"
}
}
Do anyone have a suggestion how I can replace IntentService with JobIntentService in a good way ?
IntentService is deprecated in Android-R / Android-11.
I have tried following some posts on this, but no one is directing the correct path how to change the usability of the IntentService call to JobIntentService call in the way this AddressFetchIntentService is using IntentService.
RG
class FetchAddressIntentService : JobIntentService() {
// This method is called when service starts instead of onHandleIntent
override fun onHandleWork(intent: Intent) {
onHandleIntent(intent)
}
// remove override and make onHandleIntent private.
private fun onHandleIntent(intent: Intent?) {}
// convenient method for starting the service.
companion object {
fun enqueueWork(context: Context, intent: Intent) {
enqueueWork(context, FetchAddressIntentService::class.java, 1, intent)
}
}
}
You can start the service as
val intent = Intent(this, FetchAddressIntentService::class.java)
FetchAddressIntentService.enqueueWork(this, intent)
Important:
You need to add permissions to manifest.
<uses-permission android:name="android.permission.WAKE_LOCK" /> // needed for pre-oreo devices
also
<service
android:name=".FetchAddressIntentService"
android:permission="android.permission.BIND_JOB_SERVICE" // needed for oreo and above
android:exported="true"/>
