[Android Q&A, Help & Troubleshooting] Deleted member 4932462:
Is this one the line you were talking about?

invoke-virtual {v1}, Landroid/content/pm/Signature;->hashCode()I

Or do I have to delete the full method?

In my case deleting the full method doesn't work, any help would be much apreciated ;)
