Android Studio: Layout editor preview: Custom Views not rendering properly (resource not found)

[Streets Of Boston]

Android Studio 0.2.3

Build Tools 18.0.1

Gradle 0.5.x

When I put one of my custom views in a layout, the layout editor in Android Studio throws an exception, a android.content.res.Resources$NotFoundException.

The offending Java code line is just obtaining an existing resource from my project/module (I checked whether the resource is really there), but the preview of the XML rendering in Android Studio somehow can't find it.

(BTW: resources from android.R are found without problem)

Is this a known issue?

Note that these exceptions are thrown by code in the custom views' constructors (.e.g getContext().getResources().getDrawable(....) ).

These exceptions are not thrown if the resources are specified in the XML through attributes in the "android:" namespace.

Small bump....;-)

Tor was doing some work on the resources support in the layout editor but then went on vacations. He just got back so I'm sure he'll look into this soon.

Small bump....;-)

Thanks for the update! I'll look for his reply when he's ready and back at work :)

I'm working on this stuff now; it's tracked in issues https://code.google.com/p/android/issues/detail?id=55626 and https://code.google.com/p/android/issues/detail?id=57676 (may in fact be same issue).

Thank you, Tor!

My issue seems the same as Comment #14 in  https://code.google.com/p/android/issues/detail?id=55626 and https://code.google.com/p/android/issues/detail?id=57676.

It works fine if all the resources are part of android.R (i.e. the system's resources).

It works fine in custom and non-custom views when they use my own style and theme definitions that include my own custom resources.

It does not work when my own resources are called/referenced from Java code in a custom view, and this exception is thrown, even after rebuilding the code.

Bumping for hope that Tor looks into this issue.

As far as I know those bugs were fixed in August/September. If you're seeing something similar, can you give more details on what it is you're seeing (and which version you're using). Filing a bug would be even better such that it doesn't get lost.
