Android Studio JAVA: Send SMS of user's current location ;

I am Trying to Build an app where user can show their location and send an SMS to nearby hospital.
I am new to android studio and everything about it, but I quite made a progress with it.
I have 2 XML files, but I'll provide the JAVA CLASSES first

What I want to see if its possible to send the user's current location to another phone after I hit the button that will also show their current location in the map.
I am willing to provide the source code if you kind sirs and ma'ams want to check my code.
Thank you

Can't get GPS coordinates in android application

I use this code to get the current location's coordinates. When I start this activity, nothing happens. When I use this exact code in another application it worked. The only difference that I use this location-getter in a different class, not in MainActivity. When I open that app a service comes up and starts searching the coordinates. In this case (GetLocationPS) nothing happens.
What could be the problem?

In onLocationChanged() you get location which you can use to get latitude and longitude. Also, this code does not give continuous location updates. For that you have to set UPDATE INTERVAL & FASTEST UPDATE INTERVAL in method createLocationRequest().

Access Application context data through activities

This question can be a little complex, but I try to explain it as best I can.
Basically I am trying to get last location (lat, long) with my application, so I did something like this:
public class GoogleLocation extends Activity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {
GoogleApiClient mGoogleApiClient = null;
Location mLastLocation = null;
LocationManager lm;
Double latitude;
Double longitude;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
connectLocation();
}
#Override
public void onConnected(#Nullable Bundle bundle) {
lm = (LocationManager) getSystemService(LOCATION_SERVICE);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_COARSE_LOCATION},
30);
}
}
Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if(location != null){
longitude = location.getLongitude();
latitude = location.getLatitude();
}
Log.d("IMHERE","IMHERE");
Log.d("latitude",String.valueOf(latitude));
final LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
longitude = location.getLongitude();
latitude = location.getLatitude();
//Log.d("latitudee",String.valueOf(latitude));
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
};
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 10, locationListener);
}
protected void onStart() {
mGoogleApiClient.connect();
super.onStart();
}
protected void onStop() {
mGoogleApiClient.disconnect();
super.onStop();
}
#Override
public void onConnectionSuspended(int i) {
}
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
}
public void connectLocation(){
if (mGoogleApiClient == null) {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
mGoogleApiClient.connect();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(30 * 1000);
locationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
//**************************
builder.setAlwaysShow(true); //this is the key ingredient
//**************************
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
#Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
final LocationSettingsStates state = result.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(
GoogleLocation.this, 1000);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way to fix the
// settings so we won't show the dialog.
break;
}
}
});
}
}
#Override
public void onLocationChanged(Location location) {
mLastLocation = location;
Log.d("mLastLocation",String.valueOf(location.getLatitude()));
}
#Override

}
It just works if it pass trough the onLocationChanged, so the first time it enters it takes some seconds to get the location, the second time I try that, my application already got a last location and it takes more 10 seconds to reach the new location.
At this point everything fine.
Now what I want to do is run this in background, thats why I changed the extends to activity, and try in background with that onLocationChanged to updated my location.
Something like in this example.
Every time my application detects a new location, I want to updated(do a setLocation or whatever in my class).
As I said I want to do this every time I start my application and this should run that in background, every time I access this class it should retrieve me the last location, and I want to access this class from different locations.

This code gets you location between 10 - 5 second intervals and they pass through onLocationChanged ... the GetLastKnowLocation gets you the last known location to the device... so sometimes it could return null...
CODE EXPLANATION
This code block in the OnCreate connects to the Google API Client with callbacks pointing back to the activity.
if (mGoogleApiClient == null) {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
} else {
mGoogleApiClient.connect();
}
THIS IS IMPORTANT
public class MainActivity extends Activity implements GoogleApiClient.OnConnectionFailedListener,
GoogleApiClient.ConnectionCallbacks, ResultCallback<LocationSettingsResult> ,LocationListener {
Creates A location request like yours with intervals
protected LocationRequest createLocationRequest() {
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(10000);
mLocationRequest.setFastestInterval(5000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
return mLocationRequest;
}
WHEN GOOGLE API CONNECTS CHECK SETTINGS AND PERMISSIONS
#Override
public void onConnected(Bundle bundle) {
Log.e("Connection", "GOOGLE API Connected");
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(createLocationRequest());
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient,
builder.build());
result.setResultCallback(this);
}
THE SETTINGS CALLBACK RETURNS TO ACTIVITY HERE
In this block we check the status of the settings and see if they return success we check for permission ... if we have permission to access the location ... then we getPhoneLocation() OPTION A ... if we dont have permission we ask for permission and the callback goes to OPTION B
`#Override`
public void onResult(LocationSettingsResult locationSettingsResult) {
final Status status = locationSettingsResult.getStatus();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
if (!(ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) ==
PackageManager.PERMISSION_GRANTED &&
ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) ==
PackageManager.PERMISSION_GRANTED)) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION},
222);
}
else
{
getPhoneLocation();
}
// All location settings are satisfied. The client can
// initialize location requests here.
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied, but this can be fixed
// by showing the user a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(
MainActivity.this,
111);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way
// to fix the settings so we won't show the dialog.
break;
}
}
OPTION B
In this block we get the Return from checking the user permission ... if he accepted the request for location we go on to get the PhoneLocation ... if no we close the activity.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.e("Activity","Result");
if(requestCode != 333) {
if (!(ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) ==
PackageManager.PERMISSION_GRANTED &&
ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) ==
PackageManager.PERMISSION_GRANTED)) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION},
222);
} else {
getPhoneLocation();
}
}
else
{
if(resultCode == RESULT_OK) {
finish();
}
}
}
ADD THE LOCATION REQUESTS (OPTION A)
protected void getPhoneLocation() {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
LocationServices.FusedLocationApi.requestLocationUpdates(
mGoogleApiClient, mLocationRequest, this);
}
NOW YOU HAVE LOCATION
Now you have the location in the given interval as long as the Activity is open.
#Override
public void onLocationChanged(Location location) {
lat = location.getLatitude();
lng = location.getLongitude();
}

GPS Location always remains active in notification tray after exit MapView

Original Title:
"Location set by GPS" still remains active after
LocationServices.FusedLocationApi.removeLocationUpdates()
Edited Title:
GPS Location always remains active in notification tray after exit MapView
I want to disable remove the "Location set by GPS" and the location icon in top notification tray right after exit my map activity but it doesn't.
I'm using someone's code in stackoverflow which using following variable only:
GoogleMap mGoogleMap;
MapView mapView;
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
Location mLastLocation;
Marker mCurrLocationMarker;
MapLocationListener mapLocationListener;
What I've tried:
#Override
public void onPause() {
super.onPause();
//stop location updates when Activity is no longer active
if (mGoogleApiClient != null) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, mapLocationListener);
if(mGoogleApiClient != null){
mGoogleApiClient = null;
}
if(mapView != null){
mapView = null;
}
if(mGoogleMap != null){
mGoogleMap = null;
}
if(mLocationRequest != null){
mLocationRequest = null;
}
if(mLastLocation != null){
mLastLocation = null;
}
if(mCurrLocationMarker != null){
mCurrLocationMarker = null;
}
if(mapLocationListener != null){
mapLocationListener = null;
}
}
activity.finish();
}
I understand that assigning null to my references should not be the solution because the location process is running in system background not using my app references.And Yes, the location listener is no longer update but it just not disable the location icon on top like other apps did.
What I want:disable the "Location set by GPS" and the location icon in top notification tray immediately after exit my map activity. I don't want to make my user thinks I'm doing "location hacking"What I've found:All the solution I found is using LocationManager.removeUpdate which I don't have it. How can I declare it in my activity? Is this can really solve my problem?

create interface for writing location
public interface FusedLocationDataInterface {
public void getFusedLocationData(Location location);
}
In main activity in onCreate() method create object of class FusedLocationTracker.class and implement interface in the activity.
override this method
#Override
public void getFusedLocationData(Location location) {
LatLng locate = new LatLng(location.getLatitude(), location.getLongitude());
mMap.addMarker(new MarkerOptions().title("My Location").position(locate));
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(locate, 16.0f));
}
if you want to stop the locations service call the stopLocationUpdates().

Solved.It's my fault with not getting well known understand MapView well. Just call MapView.onPause() inside my overriden onPause() solve the problem.

Android Google Map How to marker Position from ArrayList

I am using google maps on my app. I have an ArrayList where has lat, long and other information. I want to make click on a marker and go to other Activity with specific marker info to show details.
I have used this code but always get the last position of ArrayList. How to get each position's information?
