Android KeyStore Operation Failed: Unsupported Digest

I'm having an error while decrypting data using the keystore on about 1% of my users (in different API versions and device models). The crash log is: Caused by java.lang.RuntimeExc

Solution 1:

I had a same experience like you. As my researching, I decide that the reason is that the users might be done unsufforted firmware update! (For example, android P (9) in Nexus 6P, Nexus 6p's final update was 8.0.1.) you have to look at that user device is support proper os version. Let me know your check, later.
