react-native-mmkv-storage: [Bug] Android Review Rejected Unsafe Cipher Mode

Hello all,

I’m not sure if this but is 100% related to this library, but it’s the only place where i found the code that is causing the issue. So if it’s not, I apologize in advance.

I’ve used this library before on another application a while back and it was accepted and listed on the Android store. Since then I believe Android updated it’s security requirements.

Apparently Android doesn’t accept getInstance("AES"); and the only place I was able to find this in my code is in this library within SecureKeystore.java file.

The screenshot attached is from the Android Play Console, and the link mentioned on the screenshot is https://support.google.com/faqs/answer/10046138

I’m using react 0.66 and the library version installed is 0.6.6

• Has anybody seen this lately?
• Could changing this to getInstance(Constants.AES_ALGORITHM); fix the problem?

If any additional information needed please let me know. Till then I will be testing changing the code as mentioned on the second point and will update this if it works.

Regards,
