Hi there!

When I try to run Robolectric tests, I face this error: java.lang.UnsupportedOperationException: Failed to create a Robolectric sandbox: Android SDK 30 requires Java 9 (have Java 8). I follow this guideline.

Here's the configuration of my test.

Error Log

[Robolectric] WARN: Android SDK 29 requires Java 9 (have Java 8). Tests won't be run on SDK 29 unless explicitly requested.
[Robolectric] WARN: Android SDK 30 requires Java 9 (have Java 8). Tests won't be run on SDK 30 unless explicitly requested.

Approaches already used to resolve the issue

I can solve it by restricting maxSdk, like this

@RunWith(AndroidJUnit4::class)
@LooperMode(LooperMode.Mode.PAUSED)
@Config(
  application = HomeActivityTest.TestApplication::class,
  qualifiers = "port-xxhdpi",
  maxSdk = Build.VERSION_CODES.P  // <<----------------
)
@DefineAppLanguageLocaleContext(
  oppiaLanguageEnumId = ENGLISH_VALUE,
  appStringIetfTag = "en",
  appStringAndroidLanguageId = "en"
)
class HomeActivityTest {

I didn't try upgrading Java to the 9th version though.

Additional information

What's the recommended approach to fix this? I saw this issue, but I couldn't deduce a solution from it.

Thanks!

Hi @nikitaevg, I think what you need to do is select Android Instrumented Tests. Can you try these instructions and let us know? https://github.com/oppia/oppia-android/diffs/3?base_sha=590ecdf7356524d1b1412167c03040bfff35de8f&branch=wiki-updates&commentable=true&name=wiki-updates&pull_number=5174&qualified_name=refs%2Fheads%2Fwiki-updates&sha1=590ecdf7356524d1b1412167c03040bfff35de8f&sha2=aa81fab7b120ab9894b1fa54aa234addea019936&short_path=c8b1758&unchanged=expanded&w=false#set-up-and-run-tests

Thanks for the suggestion, @adhiamboperes

It causes a different problem

The application could not be installed.

Interesting. What are your emulator specifications?
