fix: Downgrade OkHttp to v4

[mahmoud-elmorabea]

Summary

This is causing errors for customers due to:

• Duplicate meta data coming from OkHttp

• Some RN code is using OkHttp 4 code and is failing when Gradle resolves dependency to v5

• OkHttp downgrade (5 → 4): Bumped OkHttp from 5.2.1 to 4.12.0 in buildSrc/.../Versions.kt. SSE usage is compatible with OkHttp 4; no code changes required.

• Packaging / META-INF exclusions removed:

  • Dropped the OkHttp-5-specific exclusion META-INF/versions/9/OSGI-INF/MANIFEST.MF from messaginginapp, samples/java_layout, and samples/kotlin_compose.
  • Removed the remaining metadata exclusions (META-INF/OSGI-INF/MANIFEST.MF and, in the Compose sample, META-INF/{AL2.0,LGPL2.1}) by deleting the packaging { resources { excludes ... } } blocks in:
    • messaginginapp/build.gradle
    • samples/java_layout/build.gradle
    • samples/kotlin_compose/build.gradle.kts

Sample apps and the SDK should be verified to build and run; if duplicate-file errors appear (e.g. for license files), re-add only the needed excludes in the affected module(s).

Note

Medium Risk
Dependency downgrade and packaging changes can affect runtime networking behavior and may reintroduce duplicate-resource build failures in specific module/consumer combinations.

Overview
Downgrades the SDK’s OkHttp dependency from 5.2.1 to 4.12.0 via Versions.OKHTTP.

Removes packaging { resources { excludes ... } } blocks from messaginginapp and the sample apps, dropping the META-INF exclusion rules that were added to work around OkHttp 5/OSGi and license resource conflicts.

Looks good, just double checking, have we verified it on

• Firebase version with progurarding
• In app which uses headers and other features of retofit for caching etc

This it was bumped only for SSE, so probably they would be fine?
