Hi @yzheng988,

Thanks for reporting this issue. I can see how this exception could be thrown if the device storage got into a particular bad state, but I'm not sure how that would have happened. Regardless, I've made some changes to improve the resiliency of the logic to allow the SDK to recover from that state. We'll have a patch release out soon with those changes.

Thanks,
@gwhelanLD

Thanks for your patience with this issue. It should be resolved in the https://github.com/launchdarkly/android-client-sdk/releases/tag/2.14.0. Feel free to reopen if this release does not resolved the errors.

Thanks again for the report,
