I have the following issue:
When looking at my output apk, I see libsentry.so takes 209KB after compression. Can it be smaller? Thank you!
Steps to reproduce:
- just compile it

- big
Expected result:
- small

You have the option of not tracking native crashes by installing
sentry-android-coreinstead ofsentry-android. That is becausesentry-androidbrings insentry-android-ndkwhich includes native libraries such aslibsentry.so.If that works for you, docs about how to do that are here: https://docs.sentry.io/platforms/android/using-ndk/#using-the-sdk-without-the-ndk
You wouldn't capture crashes from native libraries though.

@bruno-garcia I have some c++ code so I need to capture the native crashes :/ is there any ways to shrink it?
marandaneto commentedon Aug 17, 2021
@fzyzcjy currently not, but you can pre-compile your own version of https://github.com/getsentry/sentry-native and remove features that are not used by your project.

@marandaneto Thank you.

its possible that some of the codesize comes from us vendoring a libunwindstack fork, which is heavy on c++, which is not known for small code size.
Anyhow, it is currently needed, otherwise you won’t have any stack traces. But we are looking into ways to improve that in the future.

@Swatinem Thank you as well.

@Swatinem can we transfer this issue to sentry-native since the Native bits live there? https://github.com/getsentry/sentry-native/tree/3436a29d839aa7437548be940ab62a85ca699635

Sure, though I doubt there is any actionable thing we can do about code size right now. Unless we drop our custom fork of
libunwindstackand rely on the system library, which only exists on fairly recent Android versions.11 remaining items

The upcoming sentry-java 9 removes
libsentry.sofrom apps by default, so they no longer pay its size cost:sentry-androidno longer depends onsentry-android-ndkin the 9.x.x branch:Native crashes will be reported through tombstones on Android 12+ instead. Apps that need native crash reporting on older Android versions, or the NDK APIs, can still add
io.sentry:sentry-android-ndkexplicitly.
