Attempted work-arounds
You are the work-around sir 😊😎

Key error is: Multiple switch instructions refer to the same payload. This is not currently supported. Please file a bug :)

This is from Dexlib. Likely, during optimization, several execution branches are pruned and control flow collapses to a single address. Will need to come up with a work around or figure out a good way of changing the switch. It might be possible to add some nops and jump to those. Might also be possible to remove the switch, but robust modification of control flow gets a bit tricky.

To help with searching, here's the log:

One workaround, though not good, is to only optimize classes / methods you care about. Some methods optimize without upsetting dexlib.

apkunpacker · 2020-10-26T17:41:46Z

its possible to found exact location of error so i can patch with nop as you suggested ? skipping other classes is not best idea though as if someone need to simplify those similer errorpron classes they will face writing issue. something in simplify or dexlib should be tweaked to handle control flow properly . right sir ?

CalebFenton · 2020-10-26T17:46:41Z

What I said was for "future me" to understand better what to do. By "adding nops" I meant "simplify should add nops when multiple switch branches point to the same address and then modify the jump addresses to those nops so that there's no overlap". It's not something you could do manually, unless you were debugging simplify. As for the work-around, I qualified the work around as "not good" and you're correctly pointing out explicitly why it's not good.
