See also this PR for unit test example. We should probably add your PR example to that. #1833

I encountered the error when I used Gradle plugin, so the prebuilt file has used instead and comment out Gradle plugin temporarily.

The following build.gradle and the prebuilt Realm-java work.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
    }
}

repositories {
    jcenter()
}

retest this please

[dalinaum]

@emanuelez Where should I look into?

[dalinaum]

If we have annotated codes in test directory, com.neenbedankt.android-apt requires testApt for unit testing. 655b97d fixed the above problem.

[bmunkholm]

Can the example be reduced? It also includes a big CSV file.

[dalinaum]

Since I had not been sure it works fine, I had migrated many tests of RealmTest into robolectricExample. I should delete most tests after stabilising.

[cdaringe]

Whats the latest status?

[dalinaum]

It worked well before version 0.88.0, but it doesn't work now, unfortunately. I am suspecting why it doesn't work well. It will be fixed soon.

Although it will be fixed, it needs an additional CI process(or processes).

[dalinaum]

I found Android's Gradle Plugin applies Transforms for build and android test, not for unit test. I think I should add Gradle task for unit test.

So I'll add the In progress label again.

[JAertgeerts]

Any update?

[dalinaum]

@JAertgeerts Sorry. This issue's been changed to P2 Backlog. I will look into this issue soon.

[Keerthana]

any update!?

[kneth]

@Keerthana Sorry, not really. We have not worked on it lately but I hope we can return to it soon (no promises).

[tmtrademarked]

Just to chime in, this would be tremendously helpful for those of us trying to use Realm and Robolectric. What needs to happen in order to make this real? (It's not clear from the latest status updates)

[tmtrademarked]

Following back up on this one - is this at all on the roadmap?

[cmelchior]

@tmtrademarked It is on the roadmap, but not scheduled yet. Most likely we will tackle this as part of providing a general JVM API since they have similar requirements in terms of building native code for the platform running it: #2339

[vivekkiran]

@cmelchior any updates on this?
