以下のコードを使用して画像を Twitter に投稿していますが、次の行でエラーが発生します。
Token accesstoken=oAuth.getAccessToken(requestToken, verifier);
エラーを検索しましたが、解決策が見つかりませんでした。このエラーが発生する理由と、何が間違っているのかを知りたいです。
OAuthService oAuth = new ServiceBuilder()
.provider(TwitterApi.class)
.apiKey("6JyIkj71ZqG4wk3YF0Y4hw") // REPLACE WITH YOUR OWN!!!
.apiSecret("sJl9aRVqlEt7nxlKvpMVK6tLULz5FSQ2KUOW0yie4") // REPLACE WITH YOUR OWN!!!
.callback(TwitterApp.CALLBACK_URL) // REPLACE WITH YOUR OWN!!!
.build();
Log.e("hi", "hi");
Token requestToken = oAuth.getRequestToken();
if (requestToken != null) {
Log.e("has requestToken", "has");
}
String authUrl = oAuth.getAuthorizationUrl(requestToken);
Verifier verifier = new Verifier(getVerifier(authUrl));
if (verifier != null) {
Log.e("verifier created", "created");

Log.e("raw resp", accesstoken.getRawResponse());

Log.e("hello", "hhello");
Log.e("access token", "hi" + accesstoken.toString());
