How can I get my current location in Android using GPS?

Solution 1

In your AndroidManifest.xml, you have to put this above or below the application tag.

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Because you did not show your code what you have been doing, so I have no clue how to resolve your problems. But the below code is the code I use for my application to get the current country of users.

activity_main.xml

    <?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/text_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

MainActivity.java

import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;
import android.location.Address;
import android.location.Geocoder;
import android.location.Location;
import android.location.LocationManager;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

import java.util.List;
import java.util.Locale;

public class MainActivity extends AppCompatActivity {

        Location gps_loc;
        Location network_loc;
        Location final_loc;
        double longitude;
        double latitude;
        String userCountry, userAddress;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        TextView tv = findViewById(R.id.text_view);

        LocationManager locationManager = (LocationManager) getSystemService(Context.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
                && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_NETWORK_STATE) != PackageManager.PERMISSION_GRANTED) {

            return;
        }

        try {

            gps_loc = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
            network_loc = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

        } catch (Exception e) {
            e.printStackTrace();
        }

        if (gps_loc != null) {
            final_loc = gps_loc;
            latitude = final_loc.getLatitude();
            longitude = final_loc.getLongitude();
        }
        else if (network_loc != null) {
            final_loc = network_loc;
            latitude = final_loc.getLatitude();
            longitude = final_loc.getLongitude();
        }
        else {
            latitude = 0.0;
            longitude = 0.0;
        }


        ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_NETWORK_STATE}, 1);

        try {

            Geocoder geocoder = new Geocoder(this, Locale.getDefault());
            List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
            if (addresses != null && addresses.size() > 0) {
                userCountry = addresses.get(0).getCountryName();
                userAddress = addresses.get(0).getAddressLine(0);
                tv.setText(userCountry + ", " + userAddress);
            }
            else {
                userCountry = "Unknown";
                tv.setText(userCountry);
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

You will have to understand this code. One more thing, if you run your application on an emulator, it will keep showing "United States" or more specifically, Googleplex's location. Just run it on a real device to make it return your current location.

To return your current location other than just country itself, you can replace the

addresses.get(0).getCountryName()

with something like

addresses.get(0).getPostalCode()

addresses.get(0).getAdminArea()

and so on.

You can too concatenate the values as a string to show your current location in detail.

Please have a look at this

Solution 2

You can use Google's Fused Location Profivider API library to get and access your current location (given that your GPS service is turned on)

Also don't forget to add this to your AndroidManifest.xml

 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

For a more detailed tutorial you can refer at this Medium GPS Tutorial

Please try the below way here you can get location using the gps and network both

 public class LocationTracker {

    public static String TAG = LocationTracker.class.getName();

    boolean isGPSEnabled = false;
    boolean isNetworkEnabled = false;
    boolean canGetLocation = false;
    Location location = null;
    private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 0;
    private static final long MIN_TIME_BW_UPDATES = 1000;
    protected LocationManager locationManager;
    static Context mcontext;
    private static LocationTracker instance;


    public static synchronized LocationTracker getInstance(Context ctx) {
        mcontext = ctx;
        if (instance == null) {
            instance = new LocationTracker();
        }
        return instance;
    }

    myListener listener;
    public void connectToLocation(myListener listener) {
        this.listener=listener;
        stopLocationUpdates();
        displayLocation();
    }

    private void displayLocation() {
        try {
            Logger.i(TAG,"displayLocation");
            Location location = getLocation();
            if (location != null) {
                updateLattitudeLongitude(location.getLatitude(), location.getLongitude());
            }
        } catch (SecurityException e) {
            ExceptionHandler.printStackTrace(e);
        } catch (Exception e) {
            ExceptionHandler.printStackTrace(e);
        }
    }

    public Location getLocation() {
        try {
            locationManager = (LocationManager) mcontext
                    .getSystemService(Context.LOCATION_SERVICE);

            isGPSEnabled = locationManager
                    .isProviderEnabled(LocationManager.GPS_PROVIDER);

            isNetworkEnabled = locationManager
                    .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

I want to get my current location in the form of an address by GPS. I am using the android studio. It is saying that my application stops working. What is the error in it? Can someone help me to get out of this, please?

My Code in activity_main.xml file is

<?xml version="1.0" encoding="utf-8"?>

Please show some code also what you have been tried so far
Arpit J. over 4 years

Natively you can only get coordinates using gps. You want to get Address like google maps?
SudeepaNoble over 4 years

@ArpitJ. I think it is possible to convert coordinates to show the location in google maps using reverse geocoding.
SudeepaNoble over 4 years

@CyrilleConMorales All the codes I have tried are not the recent versions and they are posted 3 years ago. So, I did not post the code. I am still a beginner and that made me ask you the process. Thankyou

depending on device, this may not be the best idea. My work manages 600 tablets that don't get software through the play store,and fused location provider relies on play services, which google forces you to update often. If you don't, you lose play services which breaks fuse location provider. We had to manually update 600 tablets.
ralphgabb over 4 years

Yes. But in most cases this is a best plan if you are developing the norm. In your case you can use the native LocationManager to access GPS data
John Lord over 4 years

like i said, depends on device. Note that i've also seen a tablet (specifically the new tab a from samsung) that we had to disable every location source besides gps because it was screwing it up. Your mileage may vary.

Look, my countryEdit variable is a spinner and the countryAdapter variable is ArrayAdapter<String>. Do you use a spinner by any chance? please let me know.

No, I did not use it anytime before. I just tried the code you sent me. Can you please tell me the entire code including activity.xml file. It will be very helpful for me.
Suri over 4 years

That's the only relevant code. I assume you are using a text view to do this, so I have changed it to text view instead of a spinner. If there is any mistake, tell me pls.

error: cannot find symbol variable text_view. I am now getting this. I have imported android.widget.textview also. What should I do now.
Suri over 4 years

You must create the text view in an xml file by calling its id "text_view".
Suri over 4 years

I have made the code clearer. Now you can have a look.
SudeepaNoble over 4 years

Yes. I've created Id as textview and it is working finally. But after opening the application, I'm not getting anything. Should I include any other buttons in text view?
Suri over 4 years

No need. When you open your app, there should be a pop-up window asking you for accessing your location, then you must click "allow" otherwise it will return "Unknown".
SudeepaNoble over 4 years

There's no pop up window coming for me. It is saying that application keeps stopping. Can you please help me in doing it.

You missed the line "ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_NETWORK_STATE}, 1);".

This is also a working one. Just Copy/Paste is enough
SudeepaNoble over 4 years

Still my application keeps stopping even after including the line.

What does the log say?

Can you try the code for getting the address using reverse geocoding?? If you already have an idea, can you help me with that?
Suri over 4 years

Can you show your logcat when you run your app pls.
SudeepaNoble over 4 years

Can you please see it now.

@JohnLord, if not use Fused Location Profivider and update Play Services seldom (or never), will LocationManager.getLastKnownLocation work well?
John Lord almost 4 years

i would think so. All the google play wrapper does is add some events for you to use and auto-switches to the best current location. This could conceivably be wifi if you are in a city. Note that the underlying behavior depends on the OS version. Newer ones only trigger new points when you are moving or when they get around to giving you a point vs when you ask for it. It prevents bogging the system down.

please also mention how to use it in a activity so that it helps everyone

Just try to use..... LocationTracker.getInstance(this). connectToLocation();... from activity......you can also extend or add with your interface listener to update this from updateLattitudeLongitude method to update in ui/activity class.
