c# - Push-notifications and MVVMCross -


we facing problem handling notification on android mvvmcross.

i implemented default void createnotification() when tap notification in notification center, oncreate() fails following exception:

system.nullreferenceexception: object reference not set instance of object

the code using:

var notificationmanager = (notificationmanager)getsystemservice(notificationservice);  //create intent show ui var uiintent = new intent(this, typeof(homeview));  var notification = new notification(android.resource.drawable.staron, title); notification.flags = notificationflags.autocancel;  notification.setlatesteventinfo(this, title, desc, pendingintent.getactivity(this, 0, uiintent, pendingintentflags.updatecurrent));  notificationmanager.notify(1, notification);

the homeview in sample of type:

public abstract class mvxbindingactivityview : cirrious.mvvmcross.droid.views.mvxactivityview tviewmodel : class, cirrious.mvvmcross.interfaces.viewmodels.imvxviewmodel member of cirrious.mvvmcross.binding.droid.views

can fix problem?

thanks, christian

providing nullreference exception without trace or call stack info asking 'long shot' guesses... please try provide more if can - eg catching exception , tracing callstack and/or looking @ output window or monitor.bat trace.

with said, long shots... , suspect problem in way showing activity - show mvxactivity need provide serialised mvxviewmodlerequest in intent extras - easiest way use showviewmodel api on mvxnavigatingobject (mvxapplicationobject in vnext). alternatively can use object implements https://github.com/slodge/mvvmcross/blob/vnext/cirrious/cirrious.mvvmcross.droid/interfaces/imvxandroidviewmodelrequesttranslator.cs - can using ioc

i hope guess right - if not, stack trace , log output please :)

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
