Possible to avoid changes to assets? (sentry-debug-meta.properties)

[Jonny1987]

Description

I'm using a tool to patch my app to avoid needing to create a new release for every change (Shorebird). However patches can not be made when assets have changed.

When using Sentry Android Gradle Plugin, the file sentry-debug-meta.properties is changed every time a new build is created which means I can't use shorebird to patch my app.

Is there a way around this?

Hey @Jonny1987, thanks for reaching out! This is an interesting use case we should definitely support. This issue most likely is caused by us generating a new ProGuard UUID due to ProGuard/R8 running again for the release build. We store an UUID identifier inside that file, in order to be able to de-obfuscate native (Java/Kotlin) stacktraces at a later point.

Could you elaborate a bit on your setup?

• If you rebuild your app, does ProGuard / R8 run?
• Does the Sentry Android Gradle plugin upload your ProGuard mappings?
• Do you have an special sentry {} Gradle configuration?

Hi! Great, that's good to hear. Actually I think it's the bundle-ids which is changing on every build, but I think the ProguardUuids doesn't change if there are no native changes (since proguard mappings will only change if there are native changes, correct?). Native changes means I can't use shorebird patch anyway so this a change of ProguardUuids is not causing a problem.

Here is part of the output from shorebird patch which failed (the Bundle ID specified here is different to the bundle ID of the release build so I assume it's what is being changed in sentry-debug-meta.properties):

If you rebuild your app, does ProGuard / R8 run?

Yes, I have set minifyEnabled true in build.gradle which will run R8

Does the Sentry Android Gradle plugin upload your ProGuard mappings?

Yes, my sentry configuration in build.gradle has includeProguardMapping = true

Do you have an special sentry {} Gradle configuration?

Yes, here it is:

sentry {
    debug = false

    org = sentryOrganization
    projectName = sentryProject

    authToken = sentryAuthToken

    includeProguardMapping = true

    autoUploadProguardMapping = true

    includeSourceContext = true

    autoInstallation {
      enabled = false
    }
}
