dexcounter

For counting methods. For Dex files.

What?

Dexcounter is a CLI tool for checking how many methods a library will add to your dex file if you include it. It is inspired by the old methodscount.com service, and borrows some of its tricks.

How?

Dexcounter is written in Go, so you can go get it:

go get -u github.com/dhleong/dexcounter

Then, just pass the gradle-style dependency string like so:

dexcounter io.reactivex.rxjava2:rxkotlin:2.2.0

and off it goes! dexcounter fetches a gradle environment (from this repo) to resolve the library's dependencies, uses the dx tool to count the method references in all of them, and adds them all together. Its output currently looks something like this:

io.reactivex.rxjava2:rxkotlin:2.2.0 TOTALS:
 Methods: 17277
  Fields: 6299

Dependency                                    Methods  Fields
