the wanted logfiles

this might be a duplicate of other bugs...

I now get a "Deployment failed. The assembly directory could not be created" message whenever I try to deploy my app to a "samsung galaxy note 10.1" tab with Android 4.0.4. 
I get the same message when I want to deploy the app on an Android 2.2 emulator

You can find the logcat output and the wanted logfiles in the log.zip I will attach

This bug did not happen about a month ago. I did not use monodevelop since then so I do not know for sure when this bug appeared first :-/

Comment 1 Jonathan Pryor 2012-10-30 10:39:41 UTC
Is this a Debug or a Release app?

Do you have the shared runtime enabled or not?

Do you have fast deployment enabled or not?

Did you build the .apk with a previous Mono for Android version (e.g. 4.2.4) before attempting to deploy the .apk?

What's interesting is `log.txt` claiming it can't find mscorlib.dll. If this were a Debug app using the shared runtime, the mscorlib.dll would be provided by the Mono.Android.DebugRuntime package (which is clearly installed, as per AndroidTools.log:7-8; it would have been installed if it weren't already present).

The implication then is that the shared runtime is NOT being used. If this were a Release + non-shared-runtime app, then mscorlib.dll would instead be within the .apk.

What I suspect is happening is that you're doing a Release app with no shared runtime and with fast deployment enabled. This is an unsupported configuration, as it cannot work: Release apps don't create the fast deployment directory (the .__override__ directory that AndroidTools is looking for), so fast deployment cannot function.
Comment 2 Jens 2012-10-30 11:01:32 UTC
ok, after I activated tje "use shared runtime" option it now works again, thanks :)

BUT: this is low level stuff, which I as a normal app developer shouldn't need to know.

if there are impossible configuration because of some unknown magic, the IDE should warn the user
Or there should be some "restore defaults" option

or whatever... this is a pretty ugly usability problem :-/
Comment 3 Jonathan Pryor 2012-10-30 11:23:45 UTC
MonoDevelop (and Visual Studio, for that matter) shouldn't allow invalid configurations to be selected.
Comment 4 Mikayla Hutchinson [MSFT] 2013-05-22 16:17:11 UTC
Xamarin Studio does not permit this in the UI, but there's no way we could stop manual editing of the csproj file, so the MSBuild targets need to enforce it too, either emit a build error, or emit a warning and fall back to some sane values.

Need to check that the VS UI handles this too.
Comment 5 Jonathan Pryor 2013-05-22 17:02:58 UTC
> Need to check that the VS UI handles this too.

VS handled this by making it a valid configuration; see Bug #11421.

Furthermore, the fix is in androidtools, and thus will be "inherited" by XS.
