title: No crash data appears in release build (Android)

## Problem [#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 [#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](https://docs.newrelic.com/docs/mobile-monitoring/new-relic-mobile-android/install-configure/configure-proguard-or-dexguard-android-apps/) section in the setup documentation for guidance.
