I wrote a Unit-test with RobolectricsTestRunner included.

The unit test passed, but with the following warning:

System.logW: No Compatibility callbacks set! Querying change 119147584

All I did in the unit-test, I saved a variable in Shared Preferences. This warning doesn't destroy anything. I was just wondering what it means. Unit-Test:

@RunWith(RobolectricTestRunner::class)
@Config(sdk = [30])
class SharedPreferencesProviderTest {

    private lateinit var sharedPreferencesProvider: SharedPreferencesProviderInterface

    @Before
    fun setup() {
        // setup Shared preferences
        ...

        // Shared Preferences Access
        ...

        // clearing Shared Preferences
       ...
    }

    @Test
    fun firstStart_shouldBeTrueDefaultAndCheckChange() {
        // Default check
        var firstStart =
            sharedPreferencesProvider.getIsFirstStart()
        var expected = true
        assertTrue(firstStart == expected)

        // Check whether it handles changes
        sharedPreferencesProvider.setIsFirstStart(false)
        firstStart =
            sharedPreferencesProvider.getIsFirstStart()
        expected = false
        assertTrue(firstStart == expected)
    }}

I seems like it doesn't trigger OnSharedPreferenceChangeListener anymore, but I'm not sure. source
