Question

我正在使用Cordova的最新GCM推送通知插件。通知工作正常，但我希望应用程序在用户收到推送通知时到达前台。

我已经尝试了很多地方的几个解决方案，但是当收到通知时我仍然无法使应用程序到达前台。

似乎有人设法在这里做了类似的事情，但无论我做什么我都无法复制成功：

Bring cordova application to foreground when push arrives

他的问题中GCMIntentService.java的代码与现在的代码不同。

我怎样才能让它发挥作用？

在GCMIntentservice.java文件中的onMessageReceived方法中加入以下行。

@Override
    public void onMessageReceived(String from, Bundle extras) {
        Log.d(LOG_TAG, "onMessage - from: " + from);

        if (extras != null) {
            Context applicationContext = getApplicationContext();

            SharedPreferences prefs = applicationContext.getSharedPreferences(PushPlugin.COM_ADOBE_PHONEGAP_PUSH, Context.MODE_PRIVATE);
            boolean forceShow = prefs.getBoolean(FORCE_SHOW, false);
            boolean clearBadge = prefs.getBoolean(CLEAR_BADGE, false);

            extras = normalizeExtras(applicationContext, extras);

            if (clearBadge) {
                PushPlugin.setApplicationIconBadgeNumber(getApplicationContext(), 0);
            }

            // if we are in the foreground and forceShow is `false` only send data
            if (!forceShow && PushPlugin.isInForeground()) {
                Log.d(LOG_TAG, "foreground");
                extras.putBoolean(FOREGROUND, true);
                extras.putBoolean(COLDSTART, false);
                PushPlugin.sendExtras(extras);
            }
            // if we are in the foreground and forceShow is `true`, force show the notification if the data has at least a message or title
            else if (forceShow && PushPlugin.isInForeground()) {
                Log.d(LOG_TAG, "foreground force");
                extras.putBoolean(FOREGROUND, true);
                extras.putBoolean(COLDSTART, false);

                showNotificationIfPossible(applicationContext, extras);
            }
            // if we are not in the foreground always send notification if the data has at least a message or title
            else {
                Log.d(LOG_TAG, "background");
                extras.putBoolean(FOREGROUND, false);

                Intent wintent = new Intent(context, MainActivity.class);
            wintent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED | Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(wintent);

                extras.putBoolean(COLDSTART, PushPlugin.isActive());

                showNotificationIfPossible(applicationContext, extras);
            }
        }
    }

并确保导入 MainActivity.java
