        t.start();
    }
    protected void onActivityResult(int requestCode, int resultCode,
                                    String data, Bundle extras) {
        if (requestCode == GET_LOGIN_INFORMATION && resultCode == RESULT_OK) {
            // Save the user login information
            authInfo = data;
        }
    }
}

此处不支持2个导入文件。这些是

import android.net.http.RequestQueue;
import org.apache.commons.codec.binary.Base64;

Plz建议。

Thankx

我认为这个类不在Android官方API中：

http://developer.android.com/reference/android/net/http/package-summary.html

你应该看看这些答案： android.net.http.RequestQueue not found in andorid.jar

如何在android中使用requestqueue
