Facebook的Andr​​oid SDK和白色屏幕 [英] Facebook android SDK and white screen

问题描述

我使用Facebook的Andr​​oid SDK中允许SSO。我按照说明书和Hackbook的教程，但它发生的手机似乎stucked一个白色的屏幕上，会出现一个进度对话框10秒后，过程继续按预期。

I am using Facebook Android SDK to allow SSO. I have followed the guide and the tutorial in Hackbook but it happens that the phone seems stucked on a white screen, after 10 seconds a progress dialog appears and the process continues as expected.

我试图努力解决这些问题（异步任务，透明的布局），但它似乎没有什么工作。

I have tried hard to fix the issue (async tasks, transparent layouts) but it seems nothing is working.

这是Facebook的活动code：

This is the code in facebook activity:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.facebook_activity);
    /*
     * 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.
     */
    // showProgress();
    if (!facebook.isSessionValid()) {

        authorizeFacebook();
    } else {
        signalResult();
    }
}


private void authorizeFacebook() {
    facebook.authorize(this, new String[] { "email", "offline_access",
            "publish_stream", "user_about_me" }, new DialogListener() {
        @Override
        public void onComplete(Bundle values) {
            // SharedPreferences.Editor editor = mPrefs.edit();
            // editor.putString("access_token",
            // facebook.getAccessToken());
            // editor.putLong("access_expires",
            // facebook.getAccessExpires());
            // editor.commit();
            signalResult();
            // retrieve call obtain information and register

        }

        @Override
        public void onFacebookError(FacebookError error) {
        }

        @Override
        public void onError(DialogError e) {
        }

        @Override
        public void onCancel() {
        }
    });
}

private void signalResult() {
    // retrieve user info
    new AsyncFacebookRunner(facebook).request("me",
            new AsyncFacebookRunner.RequestListener() {

                @Override
                public void onMalformedURLException(
                        MalformedURLException e, Object state) {
                    authorizeFacebook();
                }

                @Override
                public void onIOException(IOException e, Object state) {
                    authorizeFacebook();
                }

                @Override
                public void onFileNotFoundException(
                        FileNotFoundException e, Object state) {
                    authorizeFacebook();
                }

                @Override
                public void onFacebookError(FacebookError e, Object state) {
                    authorizeFacebook();
                }

                @Override
                public void onComplete(String response, Object state) {
                    Intent intent = new Intent();
                    String accessToken = facebook.getAccessToken();
                    String id = null;
                    JSONObject json;
                    try {
                        json = new JSONObject(response);
                        id = json.getString("id");
                        intent.putExtra(WeOrderApplication.FACEBOOK_USER, id);
                        intent.putExtra(WeOrderApplication.FACEBOOK,
                                accessToken);
                        // hideProgress();
                        setResult(RESULT_OK, intent);
                        finish();
                    } catch (JSONException e) {
                        authorizeFacebook();
                        e.printStackTrace();
                    }

                }
            });

}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    facebook.authorizeCallback(requestCode, resultCode, data);
}

和它通过一个简单的StartActivity调用。 facebook_activity是在没有任何东西一个LinearLayout中。我已成立一个半透明的主题。（机器人：主题=@安卓风格/ Theme.Translucent.NoTitleBar），以FacebookActivity，使其至少透明的，但它也不能工作。

and it is called through a simple StartActivity. facebook_activity is a linearLayout without anything in it. I have set a translucent theme (android:theme="@android:style/Theme.Translucent.NoTitleBar") to FacebookActivity to make it at least transparent but it didn't work either.

由于任何人可以帮助解决这个。

Thanks to anyone that could help fixing this.
