Geofence when app is killed on Android Oreo

I'm creating a location based app which gets the current location of the user every 'x' minutes in the background, for that I'm planning to use PeriodicWorkRequest using WorkManager API.
But the thing is the minimum time for repeat interval is 15 minutes, so I thought I could use this Codelab (which uses Broadcast receiver in the pending intent) to get user's location updates, Which of the methods should I be using?
I'm planning to get Latitude and longitude coordinates from an API and create a Geofence with that latitude and longitude using Periodic Work Request Every 15 minutes in the Background, But the thing is I have Android Oreo and my Geofence does not seem to be triggered or I do not get any notification when my App is killed, I only get when app is in background or in the foreground even after I'm using Broadcast receiver for the pending intent in creating Geofence.
Also my periodic work does not seem to run as expected, because I Have put a test notification in the work and it gets executed only when I open the app for the first time and does not work after 15 minutes as it is expected to work, My Main Goal is to Create a periodic work request which runs every 15 minutes in the background, downloads location data from API and creates a geofence with that location, but since my work manager and geofence is not working properly I'm not able to achieve desired results. Any help would be appreciated. Here is the Code I'm using.

Can someone tell me what is wrong with my android app

I have written an android app which basically allows me to keep track of times and address of GPS coordinates.
I have 3 Lists each corresponding to Lyft, Uber and Other.
But I believe my app starts slowing down my Smart Phone (Samsung Galaxy S7 Edge, with Android O)
can someone look at my code and tell me why is it slowing my smart phone.
My assumption is that, possibly thread synchronization issue.

3) activity_main.xml
4) AndroidManifest.xml

This (likely) isn't a threading issue, in the normal sense of the word. What's happening is you've got a GeoCoder.getFromLocation() call executing on the main thread. Per the documentation:
The returned values may be obtained by means of a network lookup. ...It may be useful to call this method from a thread separate from your primary UI thread.
That means the method could block for several seconds each time it is called. That's more likely if you're driving through an area of spotty cell coverage. Since the method is called with each location update (roughly every 2 seconds), it's understandable that the UI is hanging.
SUGGESTED FIX
Replace your getAddress() function with an AsyncTask, which moves the getFromLocation() call to a background thread (now your app will truly be multithreaded). Something like this should work:
private class GetFromLocationTask extends AsyncTask<Location, Void, List<Address>> {
protected List<Address> doInBackground(Location... locs) {
return gcd.getFromLocation(locs[ 0 ].getLatitude(), locs[ 0 ].getLongitude(), 1);
}
protected void onProgressUpdate(Void... progress) {}
protected void onPostExecute(List<Address> result) {
//execute the remainder of your getAddress() logic here
}
}
Then, execute it using new GetFromLocationTask().execute(location). Call this instead of getAddress(). You don't need to pass a Context to getAddress(), since Service.this will work just as well (it is a Context).
Bonus hint: Note that onLocationChanged() runs on the UI thread, and so does refreshAllViews(). That means your call to runOnUiThread() is superfluous, and it will just execute the given Runnable synchronously.

Android Geo-fence not working properly

I am using geofence api for proximity but it is not working properly. some times it gives in range and out range at the same location.
i am also using GPS library to improve accuracy of geofence inrange-outrange but still it is not working properly. i am using below code for geofence :
I am using 300 meters radius for considering inrange-outrange (enter-exit)

Geofence not triggering

I'm trying to implement Geofence on my APP and the problem is that is not triggering when I'm on the place that I've marked.
The thing that I do is I set the Latitude & Longitude from a Place Picker.
The values that I'm getting are fine because I put it on google maps and the place is the correct one, because I've read many answers that people was setting bad values from lat/long.
I've two classes : GeofenceSingleton.class and GeofenceTransitionsIntentService.
The GeofenceSingleton.class looks like :
public class GeofenceSingleton implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, ResultCallback<Status> {
private GoogleApiClient googleApiClient;
private static GeofenceSingleton _singleInstance;
private static Context appContext;
private static final String ERR_MSG = "Application Context is not set!! " +
"Please call GeofenceSngleton.init() with proper application context";
private PendingIntent mGeofencePendingIntent;
private static ArrayList<Geofence> mGeofenceList;
private GeofenceSingleton() {
if (appContext == null)
throw new IllegalStateException(ERR_MSG);
this.googleApiClient = new GoogleApiClient.Builder(this.appContext)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
this.googleApiClient.connect();
mGeofenceList = new ArrayList<Geofence>();
}
/**
* #param applicationContext
*/
public static void init(Context applicationContext) {
appContext = applicationContext;
}
public static GeofenceSingleton getInstance() {
if (_singleInstance == null)
synchronized (GeofenceSingleton.class) {
if (_singleInstance == null)
_singleInstance = new GeofenceSingleton();
}
return _singleInstance;
}
#Override
public void onConnected(Bundle bundle) {
}
#Override
public void onConnectionSuspended(int i) {
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
}
public void addGeofence(Location location, String uid) {
mGeofenceList.add(new Geofence.Builder()
.setRequestId(uid)
.setCircularRegion(
location.getLatitude(),
location.getLongitude(),
500
)
.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER)
.setExpirationDuration(1000000)
.build());
}
private GeofencingRequest getGeofencingRequest() {
GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
builder.addGeofences(mGeofenceList);
return builder.build();
}
private PendingIntent getGeofencePendingIntent() {
// Reuse the PendingIntent if we already have it.
if (mGeofencePendingIntent != null) {
return mGeofencePendingIntent;
}
Intent intent = new Intent(appContext, GeofenceSingleton.class);
// We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when calling
// addGeofences() and removeGeofences().
return PendingIntent.getService(appContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}
public void startGeofencing() {
if (!googleApiClient.isConnected()) {
Toast.makeText(appContext, "API client not connected", Toast.LENGTH_SHORT).show();
return;
}
LocationServices.GeofencingApi.addGeofences(
googleApiClient,
// The GeofenceRequest object.
getGeofencingRequest(),
// A pending intent that that is reused when calling removeGeofences(). This
// pending intent is used to generate an intent when a matched geofence
// transition is observed.
getGeofencePendingIntent()
).setResultCallback(this); // Result processed in onResult().
Toast.makeText(appContext,"Geofencing started", Toast.LENGTH_LONG).show();
}
public void removeGeofence(){
LocationServices.GeofencingApi.removeGeofences(
googleApiClient,
// This is the same pending intent that was used in addGeofences().
getGeofencePendingIntent()
);
}
#Override
public void onResult(Status status) {
if (status.isSuccess()) {
// Update state and save in shared preferences.
Toast.makeText(
appContext,
"YO",
Toast.LENGTH_SHORT
).show();
} else {
Toast.makeText(
appContext,
"NOO",
Toast.LENGTH_SHORT
).show();
}
}
}
And GeofenceTransitionsIntentService
public class GeofenceTransitionsIntentService extends IntentService {
private static final String TAG = "Geofence-Service";
private Handler handler;
SharedPreferences sp;
SharedPreferences.Editor editor;
String EmailName, MessageEmail;
Context mContext;
Boolean EmailSent = false;
public GeofenceTransitionsIntentService() {
super(TAG);
}
#Override
public void onCreate() {
super.onCreate();
this.mContext = this;
sp = PreferenceManager.getDefaultSharedPreferences(this);
handler = new Handler();
}
#Override
protected void onHandleIntent(Intent intent) {
final GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
if (geofencingEvent.hasError()) {
Log.e(TAG, "Error in geofencing event");
return;
}
// Get the transition type.
final int geofenceTransition = geofencingEvent.getGeofenceTransition();
// Test that the reported transition was of interest.
if (geofenceTransition == 1) {
handler.post(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "Entered", Toast.LENGTH_SHORT).show();
sendNotification();
}
});
Log.i(TAG, "Entered");
}
else {
// Log the error.
handler.post(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "Sorry you are out", Toast.LENGTH_SHORT).show();
}
});
Log.e(TAG, String.valueOf(geofenceTransition));
}
}
private void sendNotification() {
Toast.makeText(GeofenceTransitionsIntentService.this, "HEEEEEEEY I'M IN", Toast.LENGTH_SHORT).show();
}
On my MainActivity I've got this :
GeofenceSingleton.init(this); //If I don't call this the class doesn't work
this.geofenceSingleton = GeofenceSingleton.getInstance();
And then I build a Geofence as follows :
Location geofence = new Location("");
geofence.setLatitude(Double.parseDouble(latitude));
geofence.setLongitude(Double.parseDouble(longitude));
geofenceSingleton.addGeofence(geofence, GeofenceKey);
geofenceSingleton.startGeofencing();
NOTES
I've added <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> on my manifest.xml
I declared the service as <service android:name=".GeofenceTransitionsIntentService"/>
And I added this line on my build.gradle : compile 'com.google.android.gms:play-services:7.8.0'
It only shows Toast.makeText(appContext,"YO",Toast.LENGTH_SHORT).show(); that's because status is success, and also shows the Toast.makeText(appContext,"Geofencing started", Toast.LENGTH_LONG).show(); means that it's started.
QUESTION
Why my IntentService is never called?
I tested it putting a Lat/Long of my home and since I'm on it should be triggered, isn't it?

It will never work because what you are doing is
Intent intent = new Intent(appContext, GeofenceSingleton.class);
passing intent to GeofenceSingleton ?
What you need to do is
Intent intent = new Intent(appContext, GeofenceTransitionsIntentService.class);

If your Intent is already constructed with the proper class (see varunkr's answer), you also need to make sure the service is also included in your AndroidManifest.xml.
<application
...
<service android:name=".GeofencingTransitionIntentService" />

Make sure your service and broadcast receive have these property enabled in manifest.
android:enabled="true"
android:exported="true"

Geofences not working when app is killed

I know similar questions have been asked before but answers were not perfect.
I created an app with geofences using the sample code from android developer website. I did not use any shared preferences to store geofences as I am not removing the geofences. I am testing the app from within the geofence, but my smartphone receives notifications every time the app runs and no notifications are observed when the app is killed. Why does this happen? I think I am supposed to receive notifications even when the app is killed.

Ok, May be a bit late but I'll post the answer on how I fixed this issue myself. Two things:
1) I was adding the geofences every time I run the MainActivity and geofences API triggers the geofencing event, if you add the geofences when you are already inside the specified geofence (i.e. starting the geofence app when you are already inside the geofence).
So I changed my code in the onConnected method to add the geofences only if they are not added previously. (Implemented a check using Shared preferences)
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected to GoogleApiClient");
SharedPreferences sharedPrefs = MainActivity.this.getSharedPreferences("GEO_PREFS", Context.MODE_PRIVATE);
String geofencesExist = sharedPrefs.getString("Geofences added", null);
if (geofencesExist == null) {
LocationServices.GeofencingApi.addGeofences(
mGoogleApiClient,
getGeofencingRequest(),
getGeofencePendingIntent(this)
).setResultCallback(new ResultCallback<Status>() {
#Override
public void onResult(Status status) {
if (status.isSuccess()) {
SharedPreferences sharedPrefs = MainActivity.this.getSharedPreferences("GEO_PREFS", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPrefs.edit();
editor.putString("Geofences added", "1");
editor.commit();
}
}
});
}
}
2) Turns out the reasons for not receiving notifications when the app is not available were
i) Either I toggled location services in the device(on/off/battery saving/device only/high accuracy) at least once after I added the geofences or,
ii) The device was rebooted.
To overcome this, I have added a broadcast receiver to listen to device reboots and location services toggling. In the receiver, I am adding the geofences again if the device either rebooted or location services toggled.
