Context :
apk is highly obfuscted ( all classes ) .Apk run fine but can't use simplify on it , neither can do dex2jar on it . removing Lcom/Native.smali either didn't help , it produce new similer error of another class if removed native.smali . Tried all simplify command with different values but error stay same . so i am assuming dex is not properly parsed

I wasn't able to reproduce the error until I baksmali'ed the apk and ran against the actual smali. The problem is that dexlib2 isn't able to parse the smali file. You can test this by running baksmali and then trying to smali the output. You'll get a similar error:

$ baksmali dis issue_147.apk
$ smali ass -o dexy.dex out
out/com/Native.smali[4660,4] null
out/com/mycompany/myapp/MainActivity.smali[1409,4] null

You'll need to create an issue for dexlib2 and see if they can help you with it.
