Re: [mono-android] Using the new async code in the 4.7 branch

Hi,


Why don't You try
var getLoginTask = MyEvents.UserSignIn_Async(username, password);

and see returning type??


UserSignIn_Async returns void. The compiler moaned when I tried

var getLoginTask...

Hm..
Async functions with retrun type void or type return statements must not 
have expression

(from MS docs)
Now I wonder how is this interpreted/converted? Probably void, cos Your 
function returns void;

I guess

async Task UserSignIn_Async(string username, string password)
{
return;
}

while You have:

async void UserSignIn_Async(string username, string password)
{
return;
}

and this is reason why

var retval = = MyEvents.UserSignIn_Async(username, password);

moans, You cannot assign void to variable (never crossed-my-mind/tried).



AIUI, if you're firing an event and really don't care what happens (as 
in this case), then private async void is fine
Have You tried to change sig of the function (actually this is not sig 
in c# - return value is not

considered like in c++).


I'm not sure about the RunOnUiThread part. My understanding is that as 
the call is being made in an async method, it has to jump onto the UI 
thread for something to be displayed.
I think (even Miguel has stated yesterday) that async/await is about 
freeing us from thinking

about in which context we are and where we return (await completion).

... but I'm still on reading and looking under the hood...

I still try to grasp naming/nomenclature here [lightweight] threads, 
fibers, co-routines.

It is a great help and will make code robuster and eventually faster..
But what is behind the scenes? Thread created (System.Threading.Thread) 
or not?.


I guess more reading and channel9 watching

[mono-android] EditText focus

2013-04-17 Thread laurar81 
 how do to set focus on edittext after DispatchKeyEvent?

 public override bool DispatchKeyEvent(KeyEvent e)
{
if (this.CurrentFocus.Id == Resource.Id.codice_barre)
{
if (e.Action == KeyEventActions.Down && (e.KeyCode ==
Keycode.NumpadEnter || e.KeyCode == Keycode.Enter))
{
EditText barcode =
FindViewById(Resource.Id.codice_barre);
if (barcode != null)
{
InserisciRiga(barcode);

}
}
}
return base.DispatchKeyEvent(e);
}

After InserisciRiga the edittext loses focus.

[mono-android] Linker Error in 4.7.4 beta when Referring to Mono.Android.Support.V4

2013-04-17 Thread Joshua Barker 
I think the bug that was fixed in 4.6.3 is back in 4.7.4 beta. "Fixes a Linker

This is the error.

[mono-android] "java" exited with code 1

2013-04-17 Thread Chas Xu 
Hi
I suddenly got the error when I build an Xamarin Droid project in VS2012.
The error is exactly like
http://www.blogosfera.co.uk/2013/03/why-is-my-monodroidxamarin-android-project-suddenly-giving-me-a-java-exited-with-code-1-errorI/

I ran VS 2012 update 2 this morning. I think it might cause the problem. So
I restored the system but still got this error.

Does anyone know what the problem is?

Thanks

Sorry please ignore the email. The issue has been resolved by getting all

Re: [mono-android] how to deploy mono for android app(.apk file) to android tablet

2013-04-17 Thread baramuse 
Debug .apk can of course be deployed on device, otherwise, how would you want
to debug on device ? :)
(of course you'll need to enable developper options in the tablet
preferences)

Can you provide with the build output? coud be useful to understand what's
happening.

Regards.

4.6.x branched from 4.7 long ago; 4.7 never got that fix in the first place. ;-)

We'll be fixing that error in a different way for 4.7; the 4.6 fix was "don't 
do that", i.e. "don't provide .mdb files in the .apk, ever", which is 
problematic in other circumstances. For 4.7 we'll be fixing Cecil to avoid that 
error in the first place, but this logic hasn't been fleshed out yet.

Sorry.

In the meantime...don't do Release builds on the beta against 
Mono.Android.Support*.dll. ;-)

That won't work, because Debug builds are not "stand-alone"; they have other 
dependencies which the IDE should be installing for you.

The question is, why isn't the IDE able to install the app?

Please enable device deployment logging:


http://docs.xamarin.com/guides/android/deployment,_testing,_and_metrics/diagnostics#Device_Deployment_Logs

You may need to restart Visual Studio after enabling the deployment logging. 
This will write a `monodroid.log` file to your Desktop. Please provide the 
`monodroid.log` file.

You may also need to provide your devices `adb logcat` output:


http://docs.xamarin.com/guides/android/deployment%2C_testing%2C_and_metrics/android_debug_log
