YouTube Data API v3 Authentification Error

Question

I'm trying to access the YouTube Data API v3 from within my app to fetch some videos from a specific channnel. I created an API Key and inserted my package name and the SHA-1 fingerprint. However, it does not work.

This is the error:

com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
   "code" : 403,
   "errors" : [ {
       "domain" : "usageLimits",

 "reason" : "ipRefererBlocked",
 "extendedHelp" : "https://console.developers.google.com/apis/credentials?project=1097633804344"
   } ],
       "message" : "The Android package name and signing-certificate fingerprint, null and null, do not match the app restrictions configured on your API key. Please use the API Console to update your key restrictions."

And here is the code, which sends the request:

YoutubeConnector.class

public YoutubeConnector(Context context) {
    this.context = context;
    youTube = new YouTube.Builder(new NetHttpTransport(), new JacksonFactory(), new HttpRequestInitializer() {
        @Override
        public void initialize(HttpRequest request) throws IOException {}
    }).setApplicationName("YouTube Data API v3 Test").build();

    try {
        query = youTube.search().list("id,snippet");
        query.setKey(DevKey.YOUTUBE_API);
        query.setType("video");
        query.setFields("items(id/videoId,snippet/title,snippet/description,snippet/thumbnails/default/url)");
        query.setChannelId("UC3ifTl5zKiCAhHIBQYcaTeg");
        query.setMaxResults(maxResults);
    } catch (IOException e) {
        Log.e("YoutubeConnector", "Failed to connect to YouTube: " + e.getMessage());
    }
}

public List<String> fetchVideoIDS() {

    List<String> ids = new ArrayList<>();
    maxResults += 10;

    try {
        SearchListResponse response = query.execute();
        List<SearchResult> results = response.getItems();

        for (SearchResult result : results) {
            ids.add(result.getId().getVideoId());
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

    return ids;
}

Any help is MUCH appreciated!

Answer 1

Fixed it by myself.

I was just using the wrong API key.

EDIT:

Maybe I should mention that it worked when I used an browser api key instead of an android api key.
