Codenameone 应用程序在前台时推送通知未到达

当应用程序在Android设备的前台时，我很难获得推送通知。只要我把应用程序放在后台，一切都很顺利

这是我用来发送de通知的java代码：

        HttpClient client = HttpClientBuilder.create().build();
    HttpPost httpPost = new HttpPost(URL_SERVER);
    List<NameValuePair> arguments = new ArrayList<>();   
    arguments.add(new BasicNameValuePair("token", TOKEN));        
    arguments.add(new BasicNameValuePair("device", codigoApp));      
    arguments.add(new BasicNameValuePair("type", "1"));        
    arguments.add(new BasicNameValuePair("body", ip));                    
    arguments.add(new BasicNameValuePair("auth", GOOGLE_AUTH));        
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(arguments));
        HttpResponse response = client.execute(httpPost);   
        String result = EntityUtils.toString(response.getEntity());
        System.out.println(result);
    } catch (IOException ex) {
        Logger.getLogger(NotificaReview.class.getName()).log(Level.SEVERE, null, ex);
    }

只有当我在后台接受推送后将应用程序带到前台时，ToastBar才会显示。如果应用程序处于活动状态，则不会调用推送回调

有什么想法吗？

我需要回答我在这个问题上的评论，这可能有助于解释这个问题。我将根据问题的更新编辑此答案

与此同时，我在代码中看到了几个问题。请参阅下面我突出显示的注释/修复：

public void start() {
    if(current != null){
        current.show();
        return;
    }
    // don't check the push key, always register the device and 
    // always do it in a callSerially as it might trigger a prompt
    callSerially(() -> registerPush()); 
    Form inicioGUI = new InicioGUI(Push.getPushKey());
    inicioGUI.show();
}

@Override
public void push(String value) {
  ToastBar.showMessage("Archivo recibido correctamente con IP" + value, FontImage.MATERIAL_INFO);
}

@Override
public void registeredForPush(String deviceId) {
    // deviceId is the native push key you need to use the actual 
    // push key value never device ID
    devicePush = Push.getPushKey();
}

@Override
public void pushRegistrationError(String error, int errorCode) {
    // you might have gotten a push error which might have explained the
    // cause of the problem
    Log.p("Push error " + errorCode + ":" + error);
    Log.sendLogAsync();
}

您使用的是GCM推送还是FCM推送？这是在哪个操作系统上？你测试过其他设备吗？您是否看到设备控制台上打印的内容？

public void start() {
    if(current != null){
        current.show();
        return;
    }
    // don't check the push key, always register the device and 
    // always do it in a callSerially as it might trigger a prompt
    callSerially(() -> registerPush()); 
    Form inicioGUI = new InicioGUI(Push.getPushKey());
    inicioGUI.show();
}

@Override
public void push(String value) {
  ToastBar.showMessage("Archivo recibido correctamente con IP" + value, FontImage.MATERIAL_INFO);
}

@Override
public void registeredForPush(String deviceId) {
    // deviceId is the native push key you need to use the actual 
    // push key value never device ID
    devicePush = Push.getPushKey();
}

@Override
public void pushRegistrationError(String error, int errorCode) {
    // you might have gotten a push error which might have explained the
    // cause of the problem
    Log.p("Push error " + errorCode + ":" + error);
    Log.sendLogAsync();
}
