Getting user’s latitude and longitude in Android – Java source code

In this example, user’s device is showing it’s current latitude and longitude every 5 seconds. Coordinates are displayed inside Android Toast.

First you need to add this permission inside Manifest file:

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

                Toast.makeText(getApplicationContext(), "Lat: " + latti + " Lng: " + longi , Toast.LENGTH_SHORT).show();

            } else {
                
            }

    }
