我使用Twitter sdk这个Android应用程序 . 可以按下twitter按钮，但在尝试连接到Twitter后，我得到一个简短的Toast“无法完成动作”

我的代码：

public class MainActivity extends AppCompatActivity {

TwitterLoginButton loginButton;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

Twitter.initialize(this);

setContentView(R.layout.activity_main);

TwitterConfig config = new TwitterConfig.Builder(this)

.logger(new DefaultLogger(Log.DEBUG))

.twitterAuthConfig(new TwitterAuthConfig(getString(R.string.tw__login_btn_txt), getString(R.string.tw__max_tweet_chars)))

.debug(true)

.build();

Twitter.initialize(config);

loginButton = (TwitterLoginButton) findViewById(R.id.login_button);

loginButton.setCallback(new Callback() {

@Override

public void success(Result result) {

// Do something with result, which provides a TwitterSession for making API calls

Toast.makeText(MainActivity.this, "hi", Toast.LENGTH_SHORT).show();

}

@Override

public void failure(TwitterException exception) {

// Do something on failure

}

});

}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);

// Pass the activity result to the login button.

loginButton.onActivityResult(requestCode, resultCode, data);

}

}

和错误：

授权已完成，但出现错误
