我正在使用android-facebook-sdk，我正在嘗試請求配置文件信息。但我不能得到迴應。我使用keytool生成了密鑰哈希，並將其粘貼在Facebook應用設置中。我還在代碼中添加了應用程序ID。問題是我無法獲得個人資料信息或任何信息。Android的facebook圖形請求
public class StartingPoint extends Activity {
Facebook facebook = new Facebook("actual app id");
String FILENAME = "AndroidSSO_data";
private SharedPreferences mPrefs;
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
Button btnt;
/*
* On Create

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/*

btnt = (Button) findViewById(R.id.btntallinn);
btnt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getProfileInformation();
}
});
/*
* Get existing access_token if any
*/
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if (access_token != null) {
facebook.setAccessToken(access_token);
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}
/*
* Only call authorize if the access_token has expired.
*/
if (!facebook.isSessionValid()) {
