Jitsi sdk error CRASH

Hello…Im new in android. Im trying to build app using jitsi sdk.
When I build “Build API” app working fine.
But when I generate Signed APK app is crashing.
Could someone help on this ?

this is MainActivity
public class MainActivity extends AppCompatActivity {

Button btn;
protected void onCreate(Bundle savedInstanceState) {

    btn = findViewById(R.id.button4);
    // Initialize default options for Jitsi Meet conferences.
    URL serverURL;
    try {
        serverURL = new URL("https://meet.jit.si");
    } catch (MalformedURLException e) {
        throw new RuntimeException("Invalid server URL!");
    JitsiMeetConferenceOptions defaultOptions
            = new JitsiMeetConferenceOptions.Builder()


public void onButtonClick(View view){
    String text1 = "IND-5";
    try {
        if (text1.length() > 0) {
            // Build options object for joining the conference. The SDK will merge the default
            // one we set earlier and this one when joining.
            JitsiMeetConferenceOptions options
                    = new JitsiMeetConferenceOptions.Builder()
            // Launch the new activity with the given options. The launch() method takes care
            // of creating the required Intent and passing the options.
            JitsiMeetActivity.launch(this, options);
    }catch (RuntimeException e){
