The purpose of this PR is to avoid
NPE
when the client is subscribing or disconnecting.To do that we need to expose a method to JS,
isConnected
, that checks the connection status of the client. The method invokes the methods exposed by underline libraries,Paho Android
for Android andCocoaMQTT
for iOS.Previously there was no native method that checks connection status of the client and this could create some inconsistency on the code.
