Background

We are seeing a class verification failure on startup sporadically. This is caused by the following lambda being class merged:

object ApiHelper30 {

    fun ApplicationExitInfo.toCompat() = AppExitInfoCompat(
        description = description,
        importance = importance,
        processStateSummary = processStateSummary,
        pss = pss,
        rss = rss,
        reason = reason,
        status = status,
        timestamp = timestamp,
        // Lambda referencing `ApplicationExitInfo#traceInputStream` introduced in SDK 30
        traceInputStream = { traceInputStream },
    )
}

Workaround

This can be worked around by applying the following keep rule:

-keep,allowshrinking,allowobfuscation @com.snap.framework.annotations.AvoidRuntimeVerification class * {
  *;
}

-keepclasseswithmembers,allowshrinking,allowobfuscation class * {
    @com.snap.framework.annotations.AvoidRuntimeVerification <methods>;
}

-keepclasseswithmembers,allowshrinking,allowobfuscation class * {
    @com.snap.framework.annotations.AvoidRuntimeVerification <init>(...);
}

And applying the @AvoidRuntimeVerification annotation to the lambda:

object ApiHelper30 {

    fun ApplicationExitInfo.toCompat() = AppExitInfoCompat(
        description = description,
        importance = importance,
        processStateSummary = processStateSummary,
        pss = pss,
        rss = rss,
        reason = reason,
        status = status,
        timestamp = timestamp,
        // Lambda referencing `ApplicationExitInfo#traceInputStream` introduced in SDK 30
        traceInputStream = @AvoidRuntimeVerification { traceInputStream },
    )
}

I'll share artifacts over email.
