i am facing this issue while updating firmware it keep throwing this exception though i have added proguard rules in platforms andriod resources but it still showing it,

DfuArchiveInputStream] Manifest failed to be parsed. Did you add
[DfuArchiveInputStream] -keep class no.nordicsemi.android.dfu. { ; }
[DfuArchiveInputStream] to your proguard rules?
[DfuBaseService] An exception occurred while calculating file size
