Reproducible build results for v62533 (3.32.2)

[xrviv]

Hello team Airgap!

Walletscrutiny pending MR

The diffs from 3.32.1 seems to have disappeared and what is left for 3.32.2 :

• MANIFEST.MF
• PAPERS.RSA
• PAPERS.SF

These are related to the signing differences between Google Play and the built app.

From Android Developer Documentation

Baseline Profiles improve code execution speed by about 30% from the first launch by avoiding interpretation and just-in-time (JIT) compilation steps for included code paths.

By shipping a Baseline Profile in an app or library, Android Runtime (ART) can optimize specified code paths through Ahead-of-Time (AOT) compilation, providing performance enhancements for every new user and every app update. This Profile Guided Optimization (PGO) lets apps optimize startup, reduce interaction jank, and improve overall runtime performance for users from the first launch.

Time-willing, we are interested to know how baseline.profm can be configured.
