Android: Checking if google settings location is e

Question

I'm working on an app that uses google play services. On Some phones, the client returns null for location. This happens because the locaiton option is not enabled on google setting as in the pic attached.

How to programatically check if google settings location is enabled in an android app ?

Answer 1

There should be one change, where you check TextUtils.isEmpty(locationProviders). It is never empty. Where there is no provider (location settings are disabled) it has value "null". Yes I mean value "null", not null.

Answer 2

It's possible to check if google play services itself is available. Follow instructions here: https://developer.android.com/training/location/retrieve-current.html

It's possible getLastLocation() will return null even if Google Play Services Location Services are enabled. For instance, right after re-enabling them. However you can then take your user to the Google Play Services Location Settings by using the following intent:

Intent settings = new Intent("com.google.android.gms.location.settings.GOOGLE_LOCATION_SETTINGS");
startActivity(settings);

Finally, it's also possible to check if Android Location Services are enabled:

public static boolean isLocationEnabled(Context context) {
    int locationMode = 0;
    String locationProviders;

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
        try {
            locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);

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

        return locationMode != Settings.Secure.LOCATION_MODE_OFF;

    }else{
        locationProviders = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        return !TextUtils.isEmpty(locationProviders);
    }


}

I thought this is the best solution.

You can check by following code :

    /**
     * This is used to check whether location is enabled or not.
     * @param mContext
     * @return
     */
    public static boolean isDeviceLocationEnabled(Context mContext) {
        int locMode = 0;
        String locProviders;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
            try {
                locMode = Settings.Secure.getInt(mContext.getContentResolver(), Settings.Secure.LOCATION_MODE);
            } catch (Settings.SettingNotFoundException e) {
                e.printStackTrace();
                return false;
            }
            return locMode != Settings.Secure.LOCATION_MODE_OFF;
        }else{
            locProviders = Settings.Secure.getString(mContext.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
            return !TextUtils.isEmpty(locProviders);
        }
    }

 LocationManager lm = null;
 boolean gps_enabled,network_enabled;
    if(lm==null)
        lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    try{
    gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
    }catch(Exception ex){}
    try{
    network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    }catch(Exception ex){}

   if(!gps_enabled && !network_enabled){
        dialog = new AlertDialog.Builder(context);
        dialog.setMessage(context.getResources().getString(R.string.gps_network_not_enabled));
        dialog.setPositiveButton(context.getResources().getString(R.string.open_location_settings), new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                // TODO Auto-generated method stub
                Intent myIntent = new Intent( Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                context.startActivity(myIntent);
                //get gps
            }
        });
        dialog.setNegativeButton(context.getString(R.string.Cancel), new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                // TODO Auto-generated method stub

            }
        });
        dialog.show();

    }

ACTION_LOCATION_SOURCE_SETTINGS shows the user, settings to allow configuration of current location sources.
