(Deterministic|reproducible) (compilation|builds) are a fairly recent endeavor; though they're not yet common they are technically feasible. The two efforts I'm aware of are Debian[1] and Chromium[2], though I'm not sure what state they're currently in. From their site, Chromium appears to include Android builds.

There may be Android-specific concerts w.r.t the JVM's JIT, but if you can't trust the onboard runtime, you've already lost IMO.

F-droid[3] is supposedly working on reproducible builds for Android too.
