i'm trying to develop Maps with autocomplete textview with Google API.
i tried this tutorial here
but i always get this error when i'm tryin to get the API :
{
"error_message" : "This API project is not authorized to use this API. Please ensure that this API is activated in the APIs Console: Learn more: https://code.google.com/apis/console",
"predictions" : [],
"status" : "REQUEST_DENIED"
}
i tried to find the solution, and i tried all the solution, like to use a browser key, server key, enable the google places & map, delete & recreate project, but i still get the error here is my code :
public class MainActivity extends FragmentActivity {
AutoCompleteTextView atvPlaces;
DownloadTask placesDownloadTask;
DownloadTask placeDetailsDownloadTask;
ParserTask placesParserTask;
ParserTask placeDetailsParserTask;
GoogleMap googleMap;
final int PLACES=0;
final int PLACES_DETAILS=1;

placesDownloadTask = new DownloadTask(PLACES);
// Getting url to the Google Places Autocomplete api

// Start downloading Google Places
// This causes to execute doInBackground() of DownloadTask class
placesDownloadTask.execute(url);
}
