编辑：发现我的邮件接收服务有推送通知的问题。如果我停止关闭应用程序的服务问题不再出现，但如果我点击我的手机收到的通知，它会从错误的活动启动我的应用程序... 在我的messagereceivingservice.java中我做了
postNotification(new Intent(context, NotificationsActivity.class), context);
我在Android上做一个应用程序，用户可以创建自己的个人资料与朋友互动。应用程序包括谷歌地图和推送通知实施。 我无法找到，因为当发生这种情况但是暂时如果用户停止或关闭应用程序，应用程序会在一段时间后自动重启。 因为我不能在这里发布我的所有代码，有没有人遇到过这个问题并且知道在哪里搜索这个问题的根源？可能是应用程序关闭时运行的任何服务强制应用程序重新启动？我必须说我非常绝望，因为应用程序本身完全可以解决这个问题。
至少这是我的AndroidManifest：

检查您是否从服务开始活动。也许当你收到一些gcm推送
