Help with reducing Android APK sizes
Philby Dias
Hello,
I am working on upgrading my chromium version from 114 to 138 but the chromium build itself without any customisation generates x64 APKs around 108MB in “Download size”- when analysis in Android Studio. I currently build all 4 variants for arm64, arm7, x64 and x86 and distribute separately.
I had similar issues when migrating to 126 last time and could not proceed with the upgrade, would really appreciate any assistance with this. I currently build chromium with the following args.gn:
target_os = "android"
target_cpu = "x64"
is_debug = false
android_channel = "stable"
is_official_build = true
is_component_build = false
symbol_level = 0
v8_use_external_startup_data = true
icu_use_data_file = false
ffmpeg_branding = "Chrome"
proprietary_codecs = true
update_android_aar_prebuilts = true
is_high_end_android=true
chrome_pgo_phase = 0
enable_nacl = false
enable_webrtc = false
enable_web_speech = false
And I build it using: ninja -C out/Release chrome_public_apk. Attached below is also the APK analyser result.
I realise AABs can be used to increase this limit, but I am concerned about zip align issues, especially considering once I enable play signing there is no going back and I would not want our users to be affected by getting a new application to download. So I would still prefer to somehow reduce the size of APKs if there is some way I have missed, please let me know.
Greatly appreciate your advice, thanks!
Philby
