Android String.format throwing UnknownFormatConversionException

Issue

I have the following string resource:

<string formatted="false" name="residential_search_url">https://api.trademe.co.nz/v1/Search/Property/Residential.json?latitude_min=%f%26latitude_max=%f%26longitude_min=%f%26longitude_max=%f</string>

This is being used in an Activity by:

String residentialUrl = task.getSearchUrl(_map.getProjection().getVisibleRegion().latLngBounds,getString(R.string.residential_search_url));

And the method is defined as:

public String getSearchUrl(LatLngBounds bounds, String baseUrl){
        return String.format(baseUrl,
                bounds.southwest.latitude,
                bounds.northeast.latitude,
                bounds.southwest.longitude,
                bounds.northeast.longitude);
    }

I keep getting:

java.util.UnknownFormatConversionException: Conversion = l''

I have also tried using %s in place of %f and it made no difference.

Solution

My fix was to use & to escape the ampersand, instead of %26.
