It's not possible to deploy to a Mono for Android application to an Android 4.2 device which doesn't have an admin user as the current user. (Android 4.2 adds multi-user support; not all users are admins.)

1. Take your shiny new Android 4.2 device.
2. Enable developer access: https://twitter.com/jonpryor/status/269531642551476225
3. Create a new user in Settings > Accounts > Ad account
4. Make the device sleep (hit the power button).
5. Wake up the device (hit the power button).
6. Select your new (non-admin) user.
7. Try to install an app.

(7) fails: 

>    TASK: Broadcast am broadcast -a mono.android.intent.action.SEPPUKU -c mono.android.intent.category.SEPPUKU.Mono.Samples.SanityTests Mono.Samples.SanityTests/mono.android.Seppuku completed?:Broadcasting: Intent { act=mono.android.intent.action.SEPPUKU cat=[mono.android.intent.category.SEPP...
>    :Deployment failed
>    Xamarin.AndroidTools.AndroidDeploymentException: The assembly directory could not be created.

It appears to fail because the `Seppuku` task is no longer able to cause the process to exit. Looks like we need to re-engineer Debug/fastdev deployment.

Again.

/me weeps.

It appears to be worse than that. The problem appears to be that Android will not send the broadcast to the process AT ALL when using `adb shell am broadcast` and the process is not started by the primary user.

I suspect that the only fix is to implement JDWP support and use the JDWP protocol to cause the process to exit.
Comment 2 Jonathan Pryor 2013-05-22 19:51:31 UTC
Causing the process to exit shouldn't be a problem as of 4.6.7, as we're using `adb shell am force-stop` to cause processes to exit.

However, Fast Deployment will be broken because we use the Seppuku task in order to create the fast deployment directory, so without `adb shell am broadcast` support Fast Deployment isn't possible.

Disabling Fast Deployment should allow the app to install, and thus is a workaround.
Comment 3 Jonathan Pryor 2013-05-22 19:51:54 UTC
Another workaround: Install/debug the app as the admin user.
Comment 4 Jonathan Pryor 2013-06-13 12:28:18 UTC
Comment #2 is apparently wrong, or at least not entirely right.

An (the?) issue is that each user gets a separate data directory. The fast deployment sync process assumes that it should sync with /data/data/@PACKAGE_NAME@/files/.__override__, but this is NOT the directory used for non-admin users. Instead, it's something like /data/user/10/Mono.Samples.HelloTests.

The correct directory can be obtained via android.content.pmPackageInfo -> applicationInfo.dataDir.

Fixed in androidtools/2cb4c640 and monodroid/58d28ca9.

IDE's likewise need updates.
Comment 8 Daniel Cazzulino 2015-02-12 14:44:46 UTC
md-addins@master should bump its reference to androidtools to get this.

Not sure who to assign this to.
Comment 9 Jonathan Pryor 2015-03-16 11:41:27 UTC
@kzu: md-addins@master/410686c3 (2015-Feb-11) bumped the androidtools reference to androidtools/2cb4c640.

md-addins@monodevelop-5.9-branch was branched after the above commit, and thus md-addins@monodevelop-5.9-branch will contain the required fixes.
