This is kind of a funny case because I realized (on 0.34.0) that when I renamed the text parameter of foo to anything else, the lint rule no longer reported toSpannable as unused. In this case it's not even a static import, it's just a function call with a variable that happens to match the name of an extension function.

Yes, since there was import ending with text.toSpannable, the code asssumed it to be a static import. 😞
In this PR, in addition to the prev fixes, just made sure parent import (with full package name check) exists.

there is an ElementType for the as keyword: ~.c.i.p.impl.source.tree.LeafPsiElement (AS_KEYWORD) "as"
Is it possible to check that instead? Seems slightly more robust than text matching.

That would help. But in this function, the import is sent as a String. The presence of " as " keyword comes in the subsequent node visits.

should that second param be checking for " as " too?

Pulled the " as " into a variable so as to avoid misses in check

Fixes #405
This PR contains the changes done in#437 and in addition to it has the scenario covered that was reported in #531 .
Previously the redundant import did not consider the full import path. Added the check in this PR.
There is another issue reported in #526 . Once the steps to reproduce is given, will add it as a test case in this PR to ensure no other regressions are caused.
