Xamarin Android: System.IO.Compression.ZipFile.ExtractToDirectory Fails in release mode - c#

Everything works fine in debug mode but when we run it in release the ExtractToDirectory call fails.
Here is the function for reference. Just to make sure we are not doing anything weird.
private bool UnzipFiles()
{
bool toReturn = true;
try
{
UpdateStatus("Almost done...");
string file = Path.Combine (DownloadFolder, "ZipFile.zip");
if(System.IO.Directory.Exists(UnzippingDestinationFolder))
{
System.IO.Directory.Delete(UnzippingDestinationFolder, recursive:true);
}
System.IO.Compression.ZipFile.ExtractToDirectory(file, UnzippingDestinationFolder);
UpdateStatus("Finished!");
var files = System.IO.Directory.GetFiles(UnzippingDestinationFolder);
int m = 3;
}
catch (Exception e)
{
toReturn = false;
}
Finally, here is the exception we get.

A slight changes to Victor's solution. Not linking the SDKs generated an apk that was 53MBs. Too large for the play store's apk size limit.
I set the linking behavior to link SDK assemblies only and it brought the apk size down to 29MBs
Here is the updated window.


#mattewrobbinsdev's suggestion was exactly it. For future readers, here's the dialog in Xamarin Studio:

Does the Unity compiler not fully support named parameters?

The following code compiles just fine in Visual Studio, but in Unity (4.6.x) it creates a compiler error:
public class ErrorTest
{
void DoSomething(bool a = true, bool f = true) { }
void DoSomething(int b, bool f = true) { }
public void SomeMethod()
{
DoSomething(f: false);
}
}
The call to DoSomething is what makes the compiler choke. The question is why, there's really no ambiguity.
The console output when Unity chokes like this:
Internal compiler error. See the console log for more information. output was:
Unhandled Exception: Mono.CSharp.InternalErrorException: Internal error

There was/is apparently a bug where combining the use of namespaces and default parameters caused an internal error like this. It was allegedly fixed in 4.5, but from the comments it has been allegedly fixed before. You might try eliminating the namespace declaration in your class as an experiment to see if that bug is what you're experiencing.

c# mono raspberry pi GPIO with Raspberry# getting Operation is not valid

I'm trying to use Raspberry# library to perform basic task whith GPIO pin on Raspberry PI (on and off).
As per example on github: https://github.com/raspberry-sharp/raspberry-sharp-io/wiki/Raspberry.IO.GeneralPurpose
Code:
var led1 = ConnectorPin.P1Pin11.Output();
var connection = new GpioConnection(led1);
for (var i = 0; i < 100; i++)
{
connection.Toggle(led1);
System.Threading.Thread.Sleep(250);
}
connection.Close();
on line var connection = new GpioConnection(led1); I get exception:
"Operation is not valid due to the current state of the object"
Stack trace

I am able to switch pin state with Python so nothing is wrong with device.

Execute your Mono program as root. /dev/mem is not accessible to normal users.
public GpioConnectionDriver() {
using (var memoryFile = UnixFile.Open("/dev/mem", UnixFileMode.ReadWrite | UnixFileMode.Synchronized)) {
gpioAddress = MemoryMap.Create(
IntPtr.Zero,
Interop.BCM2835_BLOCK_SIZE,
MemoryProtection.ReadWrite,
MemoryFlags.Shared,
memoryFile.Descriptor,
Interop.BCM2835_GPIO_BASE
);
}
}
Explanation from here:
http://www.raspberrypi.org/forums/viewtopic.php?f=29&t=22515
To open /dev/mem you need both regular access permissions on the device file and the security capability CAP_SYS_RAWIO, or to be root. There is no getting around this, because full access to memory allows a lot more than just GPIO. It has huge security implications.

C# Constant Stream pop3

Okay so I have came to an issue that I thought I fixed with a crappy rig and it failed in the long run, so I came to ask you guys the correct way to do it. Here is the issue I have, i'm making an application to filter out a certain type of email via POP3 (using the ActiveUp api) but I need it to have a constant connection to the POP3 server...this is what I have right now:
public static void Main (string[] args)
{
while(true)
{
POP3();
Console.Title = "Waiting for "+GetSubject+POST;
Thread.Sleep(5000);
}
}
public static void POP3()
{
Pop3Client pop3 = new Pop3Client();
try
{
pop3.ConnectSsl("pop.gmail.com",995,"", "");
if(pop3.MessageCount > 0)
{
int CurrentMessage = pop3.MessageCount;
ActiveUp.Net.Mail.Message message = pop3.RetrieveMessageObject(CurrentMessage);
if(message.Subject == GetSubject+POST)
{
Console.WriteLine("command reconized from {0}: {1}\n Sending responce now!",message.From.Email, message.Subject);
SMTP (message.From.Email, _message);
POST++;
pop3.Close();
}
}
else
{
Console.WriteLine("no mail found");
}
}
catch(Pop3Exception iex)
{
Console.WriteLine(iex);
pop3.Close();
}
}
Everything works perfect until about 10-20 minuets of it running I get kicked off of google's POP3 server and have to restart the application...Ill run the application now and reedit my question with the error...but until then can you guys please help me? Thanks!

DotCMIS/Alfresco: "error in XML document" when calling GetRootFolder

With DotCMIS I can successfully start a session to an Alfresco 4.0.1 CMIS server.
But when I call session.GetRootFolder(), I get the exception below:

An important part seems to be: Read by order only possible for encoded/bare format
My code is pretty much straight from the tutorial:
using System;
using System.Collections.Generic;
using DotCMIS;
using DotCMIS.Client.Impl;
using DotCMIS.Client;
using DotCMIS.Data.Impl;
using DotCMIS.Data.Extensions;
namespace tests.sln
{
class MainClass
{
public static void Main (string[] args)
{
// Connect to repository
Dictionary<string, string> parameters = new Dictionary<string, string>();
parameters[SessionParameter.BindingType] = BindingType.AtomPub;
parameters[SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/cmisatom";
parameters[SessionParameter.User] = "admin";
parameters[SessionParameter.Password] = "admin";
SessionFactory factory = SessionFactory.NewInstance();
ISession session = factory.GetRepositories(parameters)[0].CreateSession();
Console.WriteLine("Created CMIS session: " + session.ToString());
// Get the root folder
IFolder rootFolder = session.GetRootFolder(); // Error happens here
}
}
}
What did I miss?
In debug mode I can see DotCMIS.Client.Impl.Session.GetObject (objectId="workspace://SpacesStore/77acb21f-811c-49a3-be4d-5cc7f177f461" in the stack, not sure what it means but 77acb21f-811c-49a3-be4d-5cc7f177f461 is indeed the node reference of Alfresco's company_home.
If I change the URL to http://localhost:8080/alfresco/service/cmisatom in the code above, then a Not Found error appears earlier, at the GetRepositories line. So I am pretty sure my URL is correct.
I downloaded the DotCMIS source code and am debugging it in Monodevelop now.
With Wireshark I have identified the packet on which the exception happens:

It is valid XML.

It is a Mono bug. Mono crashes on <xsd:choice>.
See https://bugzilla.xamarin.com/show_bug.cgi?id=2907

You are using the old Alfresco CMIS URL.

Monotouch with Newtonsoft not working

I am very new to Monotouch/iOS development. I'm using

I am trying to serialize object to json string using Newtonsoft 3.5 all.
Very simple code but not working.. Can anybody can please help me ...
partial void Action_Clicked (MonoTouch.Foundation.NSObject sender)
{
myDTO test = new myDTO();
string teststring = ObjToJSON(test);
}
public string ObjToJSON(myDTO oObject) //Old function name is ObjToJSON_WithWrapper
{
string sJSON = "";
sJSON = Newtonsoft.Json.JsonConvert.SerializeObject(oObject);
return sJSON;
}
public myDTO JSONToObj(String JSONString) //Old function name is JSONToObjNew
{
myDTO deseri = JsonConvert.DeserializeObject<myDTO>(JSONString);
return deseri;
}
public class myDTO
{
public myDTO()
{
}
public string StringObject {get; set;}
}
Above is my simple test code but it's giving me error when it's run Newtonsoft.Json.JsonConvert.SerializeObject(oObject);

You need this version of Newtonsoft for MonoTouch:
