Cannot run tests with sdk < 21 anymore

[WonderCsabo]

If you have tests with @Config(sdk = 16) for example, you will get failures like this:

This is because the new DefaultPackageManager class directly references android.content.pm.PackageInstaller, but that is only available from API 21.

Workaround for this is using SDK >= 21. But i guess Robolectric clearly supports lower SDKs.

Hmmm, doesn't this fail for Robolectric's own unit tests that use MultiApiTestRobolectricRunner?

Is there any more stack trace?

[WonderCsabo]

@jongerrish here is a project which reproduces the issue. I guess the problem is that we are compiling against API 16 which does not have the referenced android.content.pm.PackageInstaller class.

[martyglaubitz]

Are there any workarounds for this?

[jongerrish]

Interesting, you're compiling against API 16? Is this common to build against such an old version of Android? Any reasons for this?

@jongerrish of course API Level 16 - 18 (Jelly Bean) coveres still 12% of all devices

[jongerrish]

Right, that's true, but you can still compile against a later SDK which allows you to selectively use new API levels. Not saying that's wrong just interesting that projects take that approach. PackageManager is kind of a special case in Robolectric, we use a custom implementation rather than a shadow which causes this issue. There is no reason why it couldn't be converted to a shadow however. We'd welcome a pull request if you're interested in contributing 😃

#2729 is a start at addressing this. As a temporary workaround, could you try adding a test dependency on 'org.robolectric:android-all:6.0.0_r1-robolectric-0'?

I'm using 3.3.2 and still the same problem:

Has it been pushed?

[jongerrish]

Robolectric 4.0 is out now, please give that a try and feel free to reopen if its still an issue and we can take a look.
