Socket works perfectly in emulator but not in Android device.
I’m using Windows 10 x64 and Fuse v 0.36.

Unfortunately it’s impossible to assist you without any information at all about what fails and how. Please provide a more detailed error report, including any relevant logs and screenshots that can help out.

You say it’s not executing, what do you mean about that? Does that function call hang. Could you try to wrap it in a try catch to get an error?

There is no error or exception to catch, i also replaced [socket.io](http://socket.io) lib with the newest version, always the same problem socket works only on emulator.

The problem persists only on Android devices.

Thank you a lot, i have found a solution while trying to make a new sample project.
Server side version must be upgraded (i used “[socket.io](http://socket.io)”: “^1.7.2”).
This param `{ "forceBase64" : 1}` is required for Android devices.
```auto
var io=require('libs/socket.io-1.4.5.js');
var socket =io.connect('url', { "forceBase64" : 1 });
//or with query
var socket=io.connect('url', { "forceBase64" : 1 ,query: 'id='+json.user._id } );
```

Hi Mehdi,
I am looking for a [socket.io](http://socket.io) implementation into Fuse app. I have things working with Cordova, but not In Fuse.
I am facing same Timer.delete() errors. Fuse v1.2 and latest [socket.io](http://socket.io) 2.0.x.
I can run the app in emulator, but preview on the phone is crashing. Base64 did not help. I did not install apk on my device.
Any clue how to solve this? Function `Delete` needs some args for execution (i think) but does not get it or takes too long to execute.
```auto
object Delete(Fuse.Scripting.Context context, object[] args)
{
if (args.Length > 1)
throw new Error("delete(): requires one argument");
try
{
var handle = Marshal.ToInt(args[0]);
_tm.DeleteTimer(handle);
}
catch (MarshalException me)
{
Fuse.Diagnostics.UserWarning("Timer.delete(): NEW ERROR TEXT HERE / TEST", this);
}
//return null;
return 8000;
}
```
I have changed the error text and return value. I does not make any change. I am still getting old error (Text).
Any ideas? Thanks
