Android - Approximate Location and Precise Location

android locations.md

Certainly! You can implement a settings screen where the user can choose between "Approximate Location" and "Precise Location". Based on their choice, you can then request the appropriate permission. Here's how you can achieve this:

1. Create a Settings Screen:

You can use SharedPreferences to store the user's choice. Provide two radio buttons or a switch/toggle for the user to select between "Approximate Location" and "Precise Location".

2. Check User's Choice:

Before requesting location, check the user's choice from SharedPreferences:

SharedPreferences preferences = getSharedPreferences("app_settings", MODE_PRIVATE);
String locationPreference = preferences.getString("location_preference", "approximate"); // default to approximate

3. Request Permission Based on Choice:

if ("approximate".equals(locationPreference)) {
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, REQUEST_CODE_APPROXIMATE);
    }
} else if ("precise".equals(locationPreference)) {
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE_PRECISE);
    }
}

4. Handle Permission Result:

Override the onRequestPermissionsResult method to handle the result of the permission request:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == REQUEST_CODE_APPROXIMATE) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Permission granted for approximate location
            // Fetch the location using NETWORK_PROVIDER
        } else {
            // Permission denied
        }
    } else if (requestCode == REQUEST_CODE_PRECISE) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Permission granted for precise location
            // Fetch the location using GPS_PROVIDER
        } else {
            // Permission denied
        }
    }
}

5. Fetch Location:

Based on the user's choice and granted permission, fetch the location using either NETWORK_PROVIDER (for approximate) or GPS_PROVIDER (for precise).

Note:

• Always provide a rationale to the user if they deny the permission, explaining why the app needs the location.
• Consider the scenario where a user might change their preference. You should handle permission revocation and re-requesting permissions accordingly.
• As always, prioritize user privacy and inform them about how their location data will be used.
