- **Release build fails but debug works** — likely an obfuscation issue. [Review ProGuard/DexGuard rules](/developers/sdks-and-tools/android/installation/specific-setup).
- **Versions 5.48.0 and 5.49.0** — incompatibility with R8 (fixed in later versions).
- **Updating from 4.3.x to 5.x.x** — Maven repository and dependency name changed. Refer to the migration guide.
