android - How to clear stack back to root activity when user leaves application? -

-

I have an application with 2 activities, logonact, and menact. LogonAct is a logon activity that I want to force the user to return to the application every time. I have set Android: LogonAct on Android: ClearTaxNowLow = "True" .

When I start the app for the first time, I go through this sequence screen

Home -> LogonAct - & gt; Menact - & gt; Home

Then I follow this sequence,

logonact -> Back - & gt; Men Act

Why is it bringing me back to the menu? That activity should not be discontinued since Android: ClearTaskOnLock = "True" next to LogonAct. I'm hoping to get back to the button from LogonAct.

Snippet related to AndroidManifest.xml, 

  & amp; Activity Android: Name = "LogonAct" Android: clearTaskOnLaunch = "true" & gt; & Lt; Intent-Filter & gt; & Lt; Action Android: name = "android.intent.action.MAIN" /> & Lt; Category android: name = "android.intent.category.LAUNCHER" /> & Lt; / Intent-Filter & gt; & Lt; / Activity & gt; & Lt; Activity Android: name = ". MainAct" & gt; & Lt; Meta-Data Android: name = "android.app.default_searchable" Android: value = ". SearchResults" /> & Lt; / Activity & gt;      
 
 
  Docs for android: ExplicitTextOneLine  mentions that this feature "whenever [the activity ] Is restarted from the home screen. "
 
 However, in your case, you will be given a < back  button to return to the home screen instead of < Kbd> Home  button means that your application is not actually  resumed  because  main act  "end" It only happens when you press  back  (or if Android drills the work to save resources.). 
 
 As you have only two activities in your application You can set the attribute on the  Main Act , thus ensuring that users never return it and will have to go through the  logon act . < / P> 
 On one side, it seems a bit annoying to users For navigating away from each other, force them to enter again (for example, when they receive a phone call). 
 You can maintain a session token with timeout in your app's continuous storage, or if your app works by opening a network connection & mdash; But of course, you and according to your needs :)

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
