Accessing GPS coordinates in same application session in which permission was provided by the user via popup window

I'd like for a user who starts the application for the first time on a device to be able to access GPS data in that session. Currently, the user must close and then restart the application after providing location permission for the location data to show in the application.
I have tried a variety of methods to resolve this. Most recently, I have moved requestPermission into Fragment1 which is also where locationManager is located.
public class Fragment1 extends Fragment {
public static final int MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION = 1;
...
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.data_capture, container, false);
requestPermission(v);
permissionAssessment(v);
...
return (v);
}
public void requestPermission(View v) {//This works, only poulates after restart...
int permissionCheck = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION);
if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_FINE_LOCATION);
//conditional here so that if conditionals granted do below, if refused, go away...
}else{
mGpsLocationListener = new GpsLocationListener();
lm = (LocationManager) getActivity().getSystemService(getActivity().LOCATION_SERVICE);
mGpsStatus = lm.getGpsStatus(mGpsStatus);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, mGpsLocationListener);
}
}
In addition, I took the caveman approach, and created "permissionAssessment()" that would run immediately following requestPermission() assuming that perhaps since permissions were likely granted by the user in requestPermission(), I could run checkSelfPermission and force location services to start that way. No cigar. See below.
public void permissionAssessment(View v){
int permissionCheck = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION);
if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
mGpsLocationListener = new GpsLocationListener();
lm = (LocationManager) getActivity().getSystemService(getActivity().LOCATION_SERVICE);
mGpsStatus = lm.getGpsStatus(mGpsStatus);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, mGpsLocationListener);
}
}
Note that permissionAssessment() works fine if the device already has ACCESS_FINE_LOCATION permissions granted. It just does not work following the newly installed permissions from requestPermission() when that is used and there were no pre-existing permissions on the device.
Furthermore, fyi this application starts on the tab associated with Fragment1 and has constantly updated gps satellite time displayed. Satellite/GPS data shows fine AFTER the application has been restarted following the session where the user granted location permissions. I'd strongly prefer that the GPS "go-live" in the session where the user sets permissions. Constructive suggestions would be appreciated. Thanks in advance.
Update, 5/14/2021: This is what ended up working for me,
public class MainActivity extends AppCompatActivity {
...
private boolean requestPermissions() {
int iExtStorage = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
int iCoarseLocation = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION);
int iFineLocation = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION);
List<String> listPermissionsNeeded = new ArrayList<>();
if (iExtStorage != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
if (iFineLocation != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(android.Manifest.permission.ACCESS_FINE_LOCATION);
}
if (iCoarseLocation != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(android.Manifest.permission.ACCESS_COARSE_LOCATION);
}
if (!listPermissionsNeeded.isEmpty())
{
ActivityCompat.requestPermissions(this,listPermissionsNeeded.toArray
(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}
getLocation();
return true;
}
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_ID_MULTIPLE_PERMISSIONS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// location-related task you need to do.
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
getLocation();
}
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
}
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
}
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
}
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
return;
}
}
}
...
}
Update #2, 5/14/2021: Per Sasaki's additional comment. This is from the fragment.
public class dataCapture extends Fragment {
...
private boolean requestPermission(View v) {
int iExtStorage = ContextCompat.checkSelfPermission(getActivity(), android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
int iCoarseLocation = ContextCompat.checkSelfPermission(getActivity(), android.Manifest.permission.ACCESS_COARSE_LOCATION);
int iFineLocation = ContextCompat.checkSelfPermission(getActivity(), android.Manifest.permission.ACCESS_FINE_LOCATION);
List<String> listPermissionsNeeded = new ArrayList<>();
if (iExtStorage != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
if (iFineLocation != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(android.Manifest.permission.ACCESS_FINE_LOCATION);
}
if (iCoarseLocation != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(android.Manifest.permission.ACCESS_COARSE_LOCATION);
}
if (!listPermissionsNeeded.isEmpty())
{
requestPermissions(listPermissionsNeeded.toArray
(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}
getLocation();
return true;
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case REQUEST_ID_MULTIPLE_PERMISSIONS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
getLocation();
}
if (ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.WRITE_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
}
if (ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
}
if (ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
}
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
return;
}
}
}
...
}

In addition, I took the caveman approach, and created "permissionAssessment()" that would run immediately following requestPermission() assuming that perhaps since permissions were likely granted by the user in requestPermission().
This approach will not work the first time when the permissions are granted by user.
This is because a prompt is shown to user for requesting permission using ActivityCompat.requestPermissions(...).
The actual granting/denial of permission would be done on a later stage when the user interacts with the prompt.
This means that the function permissionAssessment(...) which is being immediately run after the ActivityCompat.requestPermission(...) will not have the permissions hence wont run successfully for the first time and will require a Fragment "reload".
To ensure a successful run, you'll have to call the permissionAssessment(...) in the "success" callback of ActivityCompat.requestPermission(...). This is done using the function onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults).
Here's my implementation :-
public class Fragment1 extends Fragment {
public static final int REQUEST_FINE_LOCATION_CODE = 1;
...
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.data_capture, container, false);
permissionAssessment(v);
...
return (v);
}
public void permissionAssessment(View v){
int permissionCheck = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION);
if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
// Permission is granted, proceed to get location.
getLocation()
} else {
// Permission is not granted, request permissions.
// Only the prompt is shown here, nothing else will happen.
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_FINE_LOCATION_CODE);
}
}
/**
* This Function is responsible for handling what happens when permissions are granted by the user.
*/
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if (requestCode == REQUEST_FINE_LOCATION_CODE) {
if (grantResults.length > 0) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permissions Granted!
// Get Location as soon as the permissions are granted.
getLocation();
}
} else {
// Permission Denied by the user
// Show a prompt or do nothing as per your use case.
}
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
public void getLocation() {
mGpsLocationListener = new GpsLocationListener();
lm = (LocationManager) getActivity().getSystemService(getActivity().LOCATION_SERVICE);
mGpsStatus = lm.getGpsStatus(mGpsStatus);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, mGpsLocationListener);
}

I can't access GPS using Android 10 (API 29)

I use a code that worked fine with Android 4.1. But this code doesn't work any more with Android 10. The code is as follows :
LocationManager Objgps = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Objlistener = new GPSlistener();
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// Activity#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for Activity#requestPermissions for more details.
return;
}
Objgps.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, Objlistener);
and :
private class GPSlistener implements LocationListener {
public void onProviderDisabled(String provider) {
}
public void onProviderEnabled(String provider) {
}
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onLocationChanged(Location location) {
Latitude.setText(CoordHrzSoleil.DDecToDMS(location.getLatitude()));
}
}
and within the manifest :
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
It seems that it misses some extra permissions, but I don't know what they are and how to apply them.
Thank you for your help.
Pierre.

Well, finally, I found the (or a) solution ; it's the same kind of gymnastics as for writing / reading files:
In the manifest you must :
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION"/>"
Then, in the code :
if (Build.VERSION.SDK_INT >= 23) {
if (checkPermission()) {
} else {
requestPermission(); // Code for permission
}
}
...
private boolean checkPermission() {
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
&& checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
private void requestPermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, android.Manifest.permission.ACCESS_FINE_LOCATION)
&& ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, android.Manifest.permission.ACCESS_COARSE_LOCATION)) {
Toast.makeText(MainActivity.this, "Access fine and coarse location allows us to use GPS. Please allow this permission in App Settings.", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION, android.Manifest.permission.ACCESS_COARSE_LOCATION}, GPS_PERMISSION_REQUEST);
ActivityCompat.requestPermissions(MainActivity.this, new String[]{android.Manifest.permission.ACCESS_COARSE_LOCATION, android.Manifest.permission.ACCESS_COARSE_LOCATION}, GPS_PERMISSION_REQUEST);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case GPS_PERMISSION_REQUEST:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Log.e("value", "Permission Granted, Now you can use GPS .");
} else {
Log.e("value", "Permission Denied, You cannot use GPS .");
}
break;
}
}
I haven't granted permission for "ACCESS_BACKGROUND_LOCATION". I'll have to check if it's necessary.
Cordially.

How to Re-Check Permissions on Resume

My application crashes if users enable the location permission through the app, then head to their phone's settings and disable the permission there. I have tried fixing this by checking the permissions through onResume but can't seem to get it right. Other solutions on StackOverflow haven't worked.
The following code runs within my onCreate() and checks for location permissions:
if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
mMap.setMyLocationEnabled(true);
} else {
//check which API users are running.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
//location permission dialog
requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSION_FINE_LOCATION);
}
}
My onRequestPermissionsResult():
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case MY_PERMISSION_FINE_LOCATION:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
mMap.setMyLocationEnabled(true);
}
} else {
Toast.makeText(getContext(), "The app requires location permissions", Toast.LENGTH_LONG).show();
getActivity().finish();
}
break;
}
}
Here is my onResume() code within the same fragment:
#Override
public void onResume() {
super.onResume();
updatePermissions();
if (googleApiClient.isConnected()) {
requestLocationUpdates();
}
}
public void updatePermissions(){
if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
// mMap.setMyLocationEnabled(true);
} else {
//check which API users are running.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
//location permission dialog
requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSION_FINE_LOCATION);
}
}
}
The app crashes with the error:
java.lang.ArrayIndexOutOfBoundsException: length=0; index=0 at fluo.tuki10.fragments.MapFragment.onRequestPermissionsResult(MapFragment.java:232)
which is the line
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
I feel like the solution is to implement a better onResume() that checks for permissions after users modify them outside the app. Unfortunately my code falls short

An advice, before comparing it with a head that is not without elements:
if (grantResults.length> 0)

Runtime permission (requestPermissions) is not working

I have to check permission in Fragment at the runtime for getting Location.
Here is a function for checking permission.
public void weather() {
mFusedLocationClient = LocationServices.getFusedLocationProviderClient(getActivity());
try {
if (checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 123);
return;
}
mFusedLocationClient.getLastLocation()
.addOnSuccessListener(getActivity(), new OnSuccessListener<Location>() {
#Override
public void onSuccess(Location location) {
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
syncData(latitude, longitude);
}
}
});
return;
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 123) {
weather();
}
}
The issue is that my code stuck in this like a loop. It does not grant permissions and every time this if check return true and my code back and forth like a loop between override permission and if statement. And one thing more do we need this two permssion in the manifest as well?
if (checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 123);
return;
}

Try this
#Override
public void onRequestPermissionsResult(int requestCode,
#NonNull String permissions[],
#NonNull int[] grantResults) {
if (requestCode == 123) {
if (grantResults.length == 1 &&
grantResults[0] == PackageManager.PERMISSION_GRANTED) {
weather();
} else {
Toast.makeText(getActivity(), "Permission denied", oast.LENGTH_SHORT).show();
}
}
}

Try below condition in onRequestPermissionsResult
if (requestCode == 123 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
weather();
}
And you can remove and condition of ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTEDas it belongs to same permission group with ACCESS_FINE_LOCATION

gps coordinates is not working in marshmallow

I have implemented the code to get the latitude and longitude it works fine for below version 23, but not working for android Marshmallow. I have set the run time permissions also but still not working, below is my code where I am calling method.
private void configureButton() {
get_gps.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{
Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.INTERNET, Manifest.permission.ACCESS_NETWORK_STATE
}, 10);
}
}
locationManager.requestLocationUpdates("gps", 5000, 0, locationListener);
}
});
}
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case 10:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_DENIED) {
configureButton();
return;
}
}
}
