Android 从通知中调用活动将强制执行新任务，从而导致；“空白”；活动

我有一个可能接收推送通知的应用程序。此推送通知应在用户单击时启动活动。这么标准。我让它在模拟器和Galaxy S4上工作，但Nexus设备让我头疼

起初我得到：

java.lang.SecurityException: Permission Denial: start Intent 

在那个特定的活动中，我通过在清单xml中的那个活动中插入android:exported=“true”来“修复”这个问题。不确定这是否是正确的方法，但我找不到更好的方法

现在我越来越紧张了

​startActivity called from non-Activity context; forcing Intent.FLAG_ACTIVITY_NEW_TASK for: Intent 

活动已启动，但这些额外变量似乎为“null”：

导致“空”活动

以下是我在BroadcastReceiverClass中启动活动的方式：

Notification n = new Notification(icon, tickerText, when);

Intent intent = new Intent(ctx, SS9ChatActivity.class);
intent.putExtra("opponentUsername", dataObject.getString("oppo"));
intent.putExtra("gameId", dataObject.getString("game"));
PendingIntent pi = PendingIntent.getActivity(ctx, 0, intent, 0);
n.setLatestEventInfo(ctx, "Game", tickerText, pi);

n.flags |= Notification.FLAG_AUTO_CANCEL;                 
n.defaults |= Notification.DEFAULT_VIBRATE;
nm.notify(1, n);

到目前为止，我尝试在我的活动中插入

android:launchMode=“singleTop”

，但这似乎并没有解决问题

那么我做错了什么？为什么Nexus设备与emulator和我的Galaxy S4如此不同？在那里，我的应用程序运行良好

提前感谢您的帮助

这是我的全部舱单

singleTop

是正确答案。但是，您需要实现，因为传入的

Intent

不是自动设置的，因此您可以通过

getIntent（）

检索其值：

您确定这些变量不是空的吗？dataObject.getString（“oppo”）和dataObject.getString（“game”）是100%，因为我可以在日志中看到调用，并且我可以看到变量已填充，而且正如我所说，它在模拟器中的工作方式与错误“从非活动上下文调用startActivity；强制Intent.FLAG_活动_新任务：Intent这表明这里发生了一些不规范的事情。知道了。你能发布你的清单文件吗？包括我的清单：-）谢谢你的帮助，我会尽快尝试。我的代码可以在模拟器和s4上运行，但我需要为nexus设备多做一点工作，这有什么原因吗？
