Hi am using smack 4.3.4 library in my app.

implementation “org.igniterealtime.smack:smack-tcp:4.3.4”
implementation “org.igniterealtime.smack:smack-experimental:4.3.4”
implementation “org.igniterealtime.smack:smack-extensions:4.3.4”
implementation ‘org.igniterealtime.smack:smack-jingle-old:4.3.4’
implementation(“org.igniterealtime.smack:smack-android:4.3.0”)

        {
            exclude module: "smack-omemo"
            exclude module: "smack-omemo-signal"
        }

During testing am getting everything ok.

After spending 2 days I decided to ask this question. Because its asked here, github, stackoverflow many times and none of them worked.

but I found finally the solution by this article Github

He used flutter buts its not matter. all you need

disable minifyEnabled to false.
add configurations
add implementation xmlpull:xmlpull:1.1.3.4d_b4_min
as he mentioned in article in your gradle build.

Hope it will saves others peoples days.
