关闭应用程序后解析推送通知崩溃
Parse push notification crashs after the app is dismissed
是的，我知道 Parse 将于明年关闭，但出于某种原因，我现在必须使用它的功能。这是怎么回事，当应用程序处于活动状态时，推送通知部分工作正常，甚至在后台运行，但如果我关闭该应用程序，这意味着他不再 运行，当我的应用程序收到推送时它会崩溃通知。我搜索了很多，所有人都告诉我把 Parse.initialize(...) 放在应用程序上而不是 Activity，实际上我在做什么。关于我的项目有什么问题的任何线索？

这是 de PushService 中的代码，第 230 行：

PLog.e(TAG, "The Parse push service cannot start because Parse.initialize "

}
好像是最近发布的parse lib版本引起的，所以我从compile 'com.parse:parse-android:1.+'降级到编译'com.parse:parse-android:1.10.1'，现在已经解决了。另外，我必须删除 installation.put("GCMSenderId", this.getString(R.string.google_app_id)); 部分才能在应用程序死机时接收通知。
