Failed to decrypt an offline entity.

Summary

While everything is working fine, sometimes my app crashes. Even though I have been researching this problem for a long time, I cannot find what causes the problem.

I checked out breadcrumbs. Before the problem, the last request was made to take terminal-token. The result of the request appears to be 200.

Can anyone please help us looking into this issue? @gliu-stripe @rv-stripe

Hey @batuhanseckinnn, apologies for the delay here. In this case, I believe the stack trace provided may not be the root cause of the crashes you're seeing.

Some context: this particular exception indicates a problem with some of the decryption operations used to allow the Terminal SDK to collect payments offline. This usually indicates the Android device your app is running on doesn't support the cryptographic operations required for offline mode.

Even if your app is not currently using offline mode (which I think is the case for you), the SDK performs these operations in the background. However, the SDK should handle the faiures gracefully; they won't interfere with your ability to collect payments online.

Can you share more details about when you observe these crashes? If this error was the root cause, I would expect your app to crash every time you attempt to connect to a reader. However, based on our logs and your message that

While everything is working fine, sometimes my app crashes.

I believe you're seeing these crashes intermittently, sometimes after you've already begun to take payments. Is that correct?

Hello, I have the same problem now, can you tell me how you finally solved this problem

We've identified the cause of the issue and will be releasing a fix in SDK 3.8.0. See https://github.com/stripe/stripe-terminal-android/issues/474 for more details. Thanks for reporting!
