AutoComplete Google Places get error :This API project is not authorized to use this API. Please ensure that this API is activated in the APIs Console

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;

// Adding textchange listener
atvPlaces.addTextChangedListener(new TextWatcher() {

// Creating a DownloadTask to download Google Places matching "s"
placesDownloadTask = new DownloadTask(PLACES);

// Getting url to the Google Places Autocomplete api
String url = getAutoCompleteUrl(s.toString());

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

@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}

@Override

// TODO Auto-generated method stub
}
});

atvPlaces.setOnTouchListener(new View.OnTouchListener() {
@Override

atvPlaces.showDropDown();
return false;
}
});

Please help me, any help will be appreciate thanks!

Answer

I see you're using the Places API Web Service — you may find the Places API for Android suits you better as you're writing an Android app. The Places API for Android will allow you to use an Android key, which can be restricted to be only usable by your app, unlike Server keys.

For using the Web Service follow the Get a Key instructions in the Developer's Guide. In particular make sure that you:

  • Use a Server key, and
  • Have enabled Google Places API Web Service (not the same as Google Places API for Android) in the Google Developers Console.
