Is there a way to use android.py module without installing SL4A?
I mean I have Python running on android successfully from Terminal Emulator.
Can I use that module without installing that layer (or if I can't install it anymore)?
No, because the SL4A package provides the facade to make device API calls, acting as a middleman. Without it you might be able to import it, but you could not be able to make any API calls.
