In this line : For Initializing Xmpp Tcp Connection

    XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();

Internally having issue in this line in smack library:

com.android.org.kxml2.io.KXmlParser.setFeature(KXmlParser.java:2102)

This exception only comes in obfuscated code otherwise its working absolutely fine .

Hello , yes i posted the same over here as well as somebody posted a similar issue , but his solution didn’t work for me . so for visibility i posted here too , if somebody is able to answer .
Its a bit urgent for me as I am in the last phase , and had to obfuscate before publishing the app .
