Stale ProGuard rule in consumer-proguard-rules.pro does not exist in the SDK

[thanh-ha-van]

❗ Problem

The rules references a class that does not exist in the current SDK. Take this one as example:

-keep class com.launchdarkly.sdk.android.StreamUpdateProcessor$DeleteMessage { ; }

After searching the repository, I could not find:

• com.launchdarkly.sdk.android.StreamUpdateProcessor
• any nested class named DeleteMessage
• any historical reference to them via GitHub search

This indicates the rule is most likely a leftover from an older internal refactor and is no longer valid.

Because the rule points to a non-existent class:

• R8/ProGuard ignores it (harmless),
• but it adds noise,
• and it suggests that older streaming-related classes were removed or renamed without updating consumer rules.

🔍 How the issue was verified

• Searched the current main branch for the class and nested class → no matches.
• Checked package com.launchdarkly.sdk.android for any stream/update/processor classes → no match.
• Searched GitHub history for StreamUpdateProcessor and DeleteMessage → no results.

🟢 Recommendation

• Please remove this stale rule from:
• launchdarkly-android-client-sdk/consumer-proguard-rules.pro
• Or, if the class was renamed, update it to the correct current class name so that reflection/Gson usage is still protected.
• Review the whole file and update the rule correctly.

Thanks!

If you'd like, I can also prepare a PR patch that removes the stale line or proposes updated rules for R8 full mode.
