我在我们的应用程序中使用解析推送通知但在设备注册时出现一些问题,错误如下所示.当我们向设备发送推送通知时,还有一个问题,即设备收到多个通知.虽然我们也将解析库升级到Parse 1.4.1.请帮助我,提前谢谢.
首次安装应用时会显示错误:
04-14 14:00:40.004: E/LOG(26045): Socket event: onConnect

04-14 …这很简单,当你第一次在手机上使用解析时,它就像一个魅力.当您重新安装应用程序时,它会拧紧所有内容.
"PushService.subscribe似乎将订阅缓存在本地存储中,以避免在多次启动应用程序时重新订阅.这是该方法的第一个参数用于:context - 用于访问本地存储以进行缓存订阅,所以它目前必须是一个可行的上下文.(引自这里).
但是,卸载应用程序时,将从您的设备中删除该应用程序的本地存储,因此新安装将导致PushService.subscribe重新注册到Google Cloud Messaging.如果新注册返回新的注册ID,则Parse将具有两个注册ID,可用于向您的应用发送推送通知,并且它们都将链接到您提供给订阅的相同userName.因此,向该userName发送通知会将其发送到两个注册ID,导致它到达两次.
当Parse为您发送通知时,他们应该通过canonical_registration_id从Google获取回复,这会让他们知道您设备上与您的应用相关联的注册ID之一已过时,不应再使用了.因此(假设Parse有一个不错的GCM实现),下次你向设备发送通知时,你应该只收到一次."
这是我的安装源代码:
String androidId = Secure.getString(getApplicationContext().getContentResolver(),Secure.ANDROID_ID);
Parse.initialize(this, "KEY1", "KEY2");
PushService.setDefaultPushCallback(this, ParseActivity.class);
ParseInstallation installation = ParseInstallation.getCurrentInstallation();
installation.put("UniqueId",androidId);
installation.setObjectId(null);
installation.saveInBackground();
我的堆栈跟踪(像每个人一样):
