app size increased noticeably in v2.5

---

Hi,
I noticed that after the upgrade to 2.5.1, the app size increased considerably. I did a git bisect run which shows

commit 3c07bc3abc93228f7c6704417065895793645564

    Use Conscrypt; show progress bar when loading account activity

as the offending commit.
App sizes before this commit

8,6M    ./app/build/outputs/apk/standard/debug/app-standard-debug.apk
5,6M    ./app/build/outputs/apk/standard/release/app-standard-release-unsigned.apk

After this commit

12M     ./app/build/outputs/apk/standard/debug/app-standard-debug.apk
8,7M    ./app/build/outputs/apk/standard/release/app-standard-release-unsigned.apk

So, about a 50% in size increase.

Yes thats correct, we needed that!

It’s because of Conscrypt.

Can you elaborate a bit more on that? What benefits does Conscrypt offer?

It makes it possible to include new ciphers on an app-basis (packaged to the app) instead of only using the cipher suites which the base system provides. Because of that older devices with old systems like Android 4/5/6 are able to use more modern encryption techniques. At the end this makes the ecosystem more future-proof and more secure.
