当我尝试在 Twitter 上分享帖子时，我收到此错误我将 twitter4j 用于库的 Twitter 类是：
public class TwitterActivity extends Activity {
private Twitter twitter;
private RequestToken requestToken = null;
public static final String PREFS = "MyPrefsFile";
final public static String CALLBACK_URL = "app://casa";
private SharedPreferences shared;
private RequestToken re;
private int it = 0;
private String frase = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_twitter);
it = getIntent().getExtras().getInt("punteggio");
frase = getIntent().getExtras().getString("frase");
shared = this.getSharedPreferences(PREFS, Context.MODE_PRIVATE);
new updateTwitterStatus().execute();
}
@Override
public void onNewIntent(Intent data) {
super.onNewIntent(data);
dealWithTwitterResponse(data);
}
class updateTwitterStatus extends AsyncTask<Void, Void, String> {
private Intent i = null;
@Override
protected String doInBackground(Void... params) {
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey("V***********")
.setOAuthConsumerSecret(
"****************");
TwitterFactory tf = new TwitterFactory(cb.build());
twitter = tf.getInstance();
try {
// the next line throws the error
requestToken = twitter.getOAuthRequestToken(CALLBACK_URL);
Log.i("bauu", "miao");
String authUrl = requestToken.getAuthenticationURL();
startActivity(new Intent(Intent.ACTION_VIEW,
Uri.parse(requestToken.getAuthenticationURL())));
return authUrl;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
@Override
public void onResume() {
super.onResume();
}
private void dealWithTwitterResponse(Intent intent) {
Log.i("Sonod entro", "vau");
final Uri uri = intent.getData();
if (uri == null) {
Log.i("è null", "null");
}
Log.i("callback funziona", "ciao");
if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
final String verifier = uri.getQueryParameter("oauth_verifier");
final String oauthToken = uri.getQueryParameter("oauth_token");
new Thread(new Runnable() {
public void run() {
try {
Log.i("SOno dentro il run", "asd");
AccessToken at = twitter.getOAuthAccessToken(
requestToken, verifier);
twitter.setOAuthAccessToken(at);
twitter.updateStatus("CHI VUOLE ESSERE SCIENZIATO?? Punteggio: "
+ it
+ " "
+ frase
+ " "
+ "www.scienze-naturali.com");
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.punteggio, menu);
return true;
}
}
