但它一直无法获取设备令牌(couldNotFetchDeviceReferenceToken)

当初始化库时,我得到了按钮,但是当我在按钮上多次单击时,onClickListeneren只获得第一次点击(而在onClick中没有做任何事情).

获取以下错误：

12-19 16:59:41.731: ERROR/Error(4745): Authentication Failed,button not enabled.
12-19 16:59:41.739: ERROR/paypal(4745): FAIL receiving Token
12-19 17:00:06.544: ERROR/PP Init(4745): INITIALIZE_FAILURE

有谁知道我做错了什么？

这里有一些来源：

// The PayPal server to be used - can also be ENV_NONE and ENV_LIVE
private static final int server = PayPal.ENV_SANDBox;
// The ID of your application that you received from PayPal
private static final String appID = "APP-.....xxxxxxx"; 

Handler hRefresh = new Handler(){
    @Override
    public void handleMessage(Message msg) {
        switch(msg.what){
            case INITIALIZE_SUCCESS:
                //We have initialized the application,close the dialog and launch the WebView
                setupButtons();
                break;
            case INITIALIZE_FAILURE:
                setupButtons();
                //Initialization failure,close the dialog,update the page and show a toast
                //mProgDialog.cancel();
                //currentPage.update();
                break;
        }
    }
};

在onCreate中：

// Initialize the library. We'll do it in a separate thread because it requires communication with the server
        // which may take some time depending on the connection strength/speed.
        Thread libraryInitializationThread = new Thread() {
            public void run() {
                initLibrary();

                // The library is initialized so let's launch it by notifying our handler
                if (PayPal.getInstance().isLibraryInitialized()) {
                    Log.e("PP Init","INITIALIZE_SUCCESS");
                    hRefresh.sendEmptyMessage(INITIALIZE_SUCCESS);

                }
                else {
                    Log.e("PP Init","INITIALIZE_FAILURE");
                    hRefresh.sendEmptyMessage(INITIALIZE_FAILURE);
                }
            }
        };
        libraryInitializationThread.start();

这是paypal webview类：
