Androsim considers empty methods are similar #147

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
This is not a bug - but a 'design' issue which makes the androsim.py results 
less relevant.

What steps will reproduce the problem?
1. Take two Dex in particular with some empty methods

private blah() {}

2. Compare the Dex with androsim.

Androsim will say that all empty methods are "identical". Which is technically 
true, but does not generally convey any special meaning on the similarity of 
files.

3.

What is the expected output? What do you see instead?

I would prune empty methods and not consider them for comparison.

Might be worth also re-thinking what paths should be compared. For example most 
apps will have some android.annotation.TargetApi and will thus have similarity 
there, but it is usually meaningless.

Such an improvement might be considered for future versions.

What version of the product are you using? On what operating system?

Linux. Androguard from hg, v2.
