No crash data appears in release build (Android)

Problem

After an app crash, no crash data appears in the New Relic UI. You may see logs indicating that the agent is unable to find the buildId, which is required for crashes to be processed on the New Relic side.

Here are console agent log messages that verify the issue:

• Agent.getBuildId() was unable to find a valid build Id. Crashes and handled exceptions will not be accepted.
• Invalid null or empty build ID detected! Crash will be ignored by collector.
• ExceptionHelper: java.util.UUID:fromStringJava8(UUID.java:337) RandomUUID[java.lang.IllegalArgumentException] Invalid UUID string:
• Unable to get obfuscated flag in crash

Solution

If you are using Android agent 7.x.x or higher and no crash data appears after an app crash, please follow these steps:

1. Ensure you're using these Gradle and AGP versions:

   • Gradle version 7.5 or higher
   • AGP (Android Gradle Plugin) version 7.4.2 or higher

2. Configure ProGuard rules: Double-check that proper ProGuard rules are added to your ProGuard configuration file. Refer to the Configuring ProGuard Rules section in the setup documentation for guidance.
