I'm not sure what the issue is here. I added a test in the above PR and it passes. What configuration are you passing in. Can you share the code from MyApplication / LocaleHelper?

I've also removed ShadowConfiguration in the PR as I think we can just use real framework code, the shadow looked pretty incomplete and would have become out dated as new config options are added in newer SDKs, this might just magically fix your issue.

You can try this by creating your own custom shadow for config and making it have an empty class body with no @implements methods.

Hi @jongerrish,
I was able to reproduce the issue in a completely empty project just with calling

Configuration configuration = new Configuration();
base.createConfigurationContext(configuration);

You can check it here: https://github.com/AndrazP/npe-shadow-configuration

How can I override the current implementation of ShadowConfiguration?
I was not successful with @config(shadows={EmptyShadowConfiguration.class})

jongerrish · 2017-03-03T20:21:22Z

@AndrazP Can you test with Robolectric 3.3 please. We've basically removed all the implentation of ShadowConfiguration so it should be using Framework code (we left it there to give users a migration path without breaking their builds).

I wrote a test to verify your behavior so it looks like it would be fixed:-

robolectric/robolectric/src/test/java/org/robolectric/shadows/ShadowContextTest.java

Line 44 in cf2244e

    
           assertThat(RuntimeEnvironment.application.createConfigurationContext(new Configuration())).isNotNull();

Please reopen if this doesn't work on 3.3. for you.

AndrazP · 2017-03-04T13:06:10Z

It works. Thank you!

@jongerrish Im still having this issue even after I updated to Robolectric 3.3.2 somehow the Configuration is still calling ShadowConfiguration.

Test configuration:
Robolectric 3.3,3.3.2
TestSdk 17,18,21

Bellow I post my stacktrace. Any ideas?

Seeing the same stacktrace unless I use @config(sdk = N)

@jongerrish,
I am getting this with robolectric 3.8 and the following code:
Configuration conf = context.getResources().getConfiguration();
conf = new Configuration(conf);
conf.setLocale(currLanguageLocale);
Context localizedContext = context.createConfigurationContext(conf);

@tamaralu If your issue in receiving of localized string you simply have to annotate a method with @config(qualifiers="en").
