Hi!

I have cloned the samples repo into https://github.com/mosabua/RobolectricSample and therefore removed the need for the java.net repo and manually installing roboguice or guice no_aop.

Unfortunately I get a test failure that I am looking for some help to fix. All three tests in InjectedActivityTest fail with something like this

1) Error injecting constructor, java.lang.NullPointerException
  at roboguice.util.Ln$BaseConfig.<init>(Unknown Source)
  while locating roboguice.util.Ln$BaseConfig
    for field at roboguice.util.Ln.config(Unknown Source)

Anybody wanting to have a look what is going on?

PS: I will mention this on the roboguice list as well to get some help from Michael or so.. 

PPS: feel free to pull this up now or once I got it fixed ;-)

Assuming you're using the latest, looks like the relevant code in RoboGuice is the following:

                216: packageName = context.getPackageName();
                217: final int flags = context.getPackageManager().getApplicationInfo(packageName, 0).flags;


Specifically, line 217 is causing the problem.  So either the PackageManager or the ApplicationInfo is coming back null.  Is that expected in robolectric?

I am using 1.1 from Maven central. I hope to have time to look into it tonight.. I dont know enough about Robolectric yet to tell.. but I think it would need a ShadowPackageManager and a ShadowApplicationInfo ... not sure they exist yet..

Hi Manfred,

This problem has been reported elsewhere (https://github.com/pivotal/robolectric/issues#issue/45) and is related to the StubPackageManager returning null on the getApplicationInfo() call (https://github.com/pivotal/robolectric/blob/master/src/main/java/com/xtremelabs/robolectric/tester/android/content/pm/StubPackageManager.java).

From a separate thread in the Robolectric forum (http://groups.google.com/group/robolectric/browse_thread/thread/3d03a56bb595b7cc) it seems this work is scheduled, although it is suggested someone submit a pull request...As I am suffering the same problem I may take a look.

Cheers,
Rob

That would be great since it would fix the samples project up to work with Roboguice 1.1 and Google Guice 2.0 no aop all supplied from Maven central and therefore lower the barrier for people trying it.

FYI, in case anyone is interested.  Here is what I had to do to fix the Ln binding issue.  Note this is using RoboGuice 1.2-SNAPSHOT not 1.1 so some of it might look a little funky.

I'm having the same problem as the OP. I just cloned the roberttaylor
fork and ran my test again, but I'm still getting the same problem. Is
there any special setup that I need to do to get this to work?

Ok, I just got it to work. I needed to get a newer version of
RoboGuice; after cloning the 1.1.1-SNAPSHOT version, it worked.

That's strange, the fork *should* work with 1.1....(hey, it's working
for me :))

I believe the reason 1.1.1-SNAPSHOT is working fine is because a fix/
workaround for this issue was created on the RoboGuice side (http://
groups.google.com/group/roboguice/browse_frm/thread/69e7601a756526cb).

Can you give a stacktrace of the error you're seeing when using
RoboGuice 1.1?

Hmm, that indeed appears to be the problem that the Shadow
ApplicationInfo classes were supposed to fix. I'm a little perplexed -
I have this fork of Robolectric running fine with RoboGuice 1.1 in a
couple of different projects. I guess if 1.1.1-SNAPSHOT is working for
you though then it's not such a problem.
