I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @fanwgwg, thank you for reaching out. I tried to reproduce the issue, but I did not encounter an ANR. Usually, ANR issues are difficult to isolate.

Based on the stack trace, it looks the issue occurs on initRC method that triggers triggers Firebase Auth, could you share more how does the method works? By any chance, could share an MCVE to help us investigate the issue.

Aside from that, I wonder if this is a device specific issue, would you be able to check on that?

[fanwgwg]

Hi, here's the initRC method:

  public static void initRC(Context context) {
    Purchases.setLogLevel(AppUtils.isReleaseBuild() ? LogLevel.ERROR : LogLevel.DEBUG);
    PurchasesConfiguration.Builder purchaseConfigurationBuilder =
        new PurchasesConfiguration.Builder(context, CredentialUtils.getRevenueCatPublicApiKey())
            .pendingTransactionsForPrepaidPlansEnabled(true);
    if (AccountManager.checkIsSignedIn()) {
      purchaseConfigurationBuilder.appUserID(AccountManager.getCurrentUserId());
    }
    Purchases.configure(purchaseConfigurationBuilder.build());
  }

I also suspect that this is device specific, because these devices are not common devices from our users

Hey @fanwgwg. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!
