A release build of an Android app will still create a writeable “.__override__” directory in the app’s data directory. According to this post, the directory is supposed to be created only for debug builds, _not_ release.
I did some testing and this seems to be a regression in 6.0 and still in the latest alpha build since the issue doesn’t occur in 5.1: https://gist.github.com/jimmgarrido/59f80b59ea742c62091e

There's a difference between *log files* saying it's *looking* for a file there, vs. *the directory actually existing*.
1. Create new project (default template).
2. Set Configuration to Release
3. Build + Run
`adb logcat` contains:
> 01-05 16:58:33.098 25736 25736 W monodroid: Trying to load sgen from: /storage/emulated/0/Android/data/scratch.bxc37422/files/.__override__/libmonosgen-2.0.so
i.e. it's *looking* for a file in the `.__override__` directory.

The directory doesn't exist.

Nor does an app-specific external storage directory.

*That* is troubling; there's no error message. It therefore exists.
Additional analysis shows that the Debug runtime is being embedded into the app, which is *not* what should be happening.
Thank you for the report.
Enable diagnostic build output, and see:
> Mandroid Task
> Debug: True
That's not good. :-(
The Debug value is $(AndroidUseDebugRuntime).
Rebuild the app with the $(AndroidUseDebugRuntime) property set to False fixes the issue:
$ xbuild /p:Configuration=Release /p:AndroidUseDebugRuntime=False /t:SignAndroidPackage App.csproj
So a "workaround" exists, but it's a workaround that shouldn't be necessary.
The problem is in (either? both?) Xamarin.Android.Common.targets and the App.csproj file.
> <AndroidUseDebugRuntime Condition="'$(AndroidUseDebugRuntime)' == '' And '$(AndroidUseSharedRuntime)' == 'False' And '$(EmbedAssembliesIntoApk)' == 'True' And '$(DebugType)' != 'Full'" >False</AndroidUseDebugRuntime>
> <AndroidUseDebugRuntime Condition="'$(AndroidUseDebugRuntime)' == ''" >True</AndroidUseDebugRuntime>
The default App.csproj as generated by Xamarin Studio 5.10.1:
> <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
We can manually walk through the //AndroidUseDebugRuntime/@Condition expression, and see that the first line will *not* be executed, i.e. $(AndroidUseDebugRuntime) will be True (the 2nd line), because $(DebugType) is Full. (Why is $(DebugType) defaulting to True?!)
Is this a recent Xamarin Studio change?
> Is this a recent Xamarin Studio change?
David Karlaš did some exploration, and it doesn't seem that Xamarin Studio has changed behavior here.
He suggests that we also check for '$(DebugSymbols)'=='True' in addition to (instead of?) '$(DebugType)'=='Full'.
Fixed in monodroid/master/532f5db7
I have reproduced this issue with stable XA 6.0.1-10. Here is the adb logcat for the same: https://gist.github.com/Abhishekk360/b4e1d2d718e023312697
I have checked this issue with master XA 126.96.36.199, C6 XA 188.8.131.52 and observed that now, ".__override__ " directory. is not exists in adb logcat, while build and run application in Release mode. Here is the adblogcat: https://gist.github.com/Abhishekk360/6d1e922f162aad67dbdf
Hence closing this issue.
Today, I have checked this issue with C6SR2 XA 184.108.40.206 and observed that ".override " directory. is not exists in adb logcat, while build and run application in Release mode.
