java - Quickblox: sample 不会开始

Question

所以我正在尝试运行 Quickblox sample chat和 XMPP Sample Chat .

我将 Eclipse 与最新的 Android sdk/build 一起使用。

导入示例后，按照 Quickblox 指南的说明，我在代码中出现了一些错误，但不多于缺少一些导入，但是当我尝试运行该应用程序时出现错误，应用程序安装正确，但在错误开始出现在 Logcat 上之后。

public class SplashActivity extends Activity implements QBCallback {

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);



    progressBar = (ProgressBar) findViewById(R.id.progressBar);

    QBSettings.getInstance().fastConfigInit(APP_ID, AUTH_KEY, AUTH_SECRET);
    QBAuth.createSession(this);
}

@Override
public void onComplete(Result result) {
    progressBar.setVisibility(View.GONE);

    if (result.isSuccess()) {

我的 list 文件是:

这是我的错误信息:

打开Properties->Java Build Path->Order and Export，勾选QB jar library。根据日志，您尚未将其添加到构建中。
