@hardikdevios This looks like it is coming from the Paho client. Can you try these proguard rules? https://github.com/eclipse/paho.mqtt.java/issues/572#issuecomment-641083671

Thank you, let me try it

@tylerjroach Proguard rules didn't work, still getting the same error

[hardikdevios]

@tylerjroach Any idea, do we require any other proguard rules to get it working?

[hardikdevios]

@tylerjroach Any way solved the issue, so I am closing the ticket

Sorry I had not gotten back to you yet but I am glad you resolved the issue. If there are any details that you can share, in case another customer runs into the same issue, it would be appreciated. Thanks!

Thanks @tylerjroach for your help here, it appears that in the newer AWS SDK, the paho client SPI NetworkModuleFactory is now created as a service in the Android META-INF which was not the case in the prior versions (we hadn't updated since last year so was a bit of a jump). Due to some other factors our apk has to be resigned via command line which has always cleared the META-INF before resigning, and losing that service file is what caused the problem :smile: After reworking the resigning process, we're back to normal :tada: Thanks again!
