pjsua2 on android - deinitalize sipstack on connection lost

[frogersik@xxxxxxxxx (frogersik)]

hi all,
im working on andorid sip app using pjsua2 and I have big problem with
managing stack when connection is lost. What I read from documetation
simplest and way is deinitalize stack, and initalize it again and here is
what im trying to do. Here is what I'm doing when I try deinitalize it:

public int DeInitializeSipStack()
    {

        if (mIsStackRunning && !isDeinitializeStarted)
        {
            isDeinitializeStarted = true;
            Log.d(TAG, "DeInitializeSipStack");


            if (toneGenerator != null)
            {
                Log.d(TAG, "DeInitializeSipStack toneGenerator");
                try
                {

toneGenerator.stopTransmit(mEndpoint.audDevManager().getPlaybackDevMedia());
                }
                catch (Exception e)
                {
                    Log.e(TAG, "", e);
                }
                toneGenerator.delete();
            }


            Log.w(TAG, "Account");
            if (mAccount != null)
            {
                mAccount.delete();
                mAccount = null;
            }

            if (mCurrentCall != null && mCurrentCall.isActive())
            {
                Log.w(TAG, "mCurrentall not null");

                try
                {
                    Log.d(this, "mCurrentall not null hangup");
                    mCurrentall.hangup(new CallOpParam(true));
                }
                catch (Exception e)
                {
                    Log.e(TAG, "", e);
                }

                if (mCurrentCall != null)
                {
                    Log.d(this, "mCurrentCall try delete");
                    mCurrentCall.delete();
                }
                mCurrentCall = null;
            }
            if (mEndpoint.libIsThreadRegistered())
            {
                Log.w(TAG, "libIsThreadRegistered");
                mEndpoint.libStopWorkerThreads();
            }

            try
            {
                AudioMediaVector audioMediaVector =
mEndpoint.mediaEnumPorts();
                for (int i = 0; i < audioMediaVector.size(); i++)
                {
                    Log.d(this, "audioMedia deleted");
                    AudioMedia audioMedia = audioMediaVector.get(i);
                    mEndpoint.mediaRemove(audioMedia);
                    audioMedia.delete();
                }
            }
            catch (Exception e)
            {
                Log.e(TAG, "", e);
            }

            Log.d(TAG, " Runtime.getRuntime().gc();");
            Runtime.getRuntime().gc();

            try
            {
                Log.d(TAG, "mEndpoint.libDestroy");
                mEndpoint.libDestroy();
            }
            catch (Exception e)
            {
                isDeinitializeStarted = false;
                Log.e(TAG, "", e);
                return -1;
            }

            mEndpoint.delete();
            mIsStackRunning = false;
            mEndpoint = null;
            mInstance = null;
            isDeinitializeStarted = false;
            Log.d(TAG, "mEndpoint.delete");
        }
        return 0;
    }

and when internet connection is lost library is stopped on
pjsua_acc.c  Deleting account 0..
lib is traying to send unregister account and wait for connection, when I
dont put account.delete I will receive error on  mEndpoint.libDestroy();

there is another issue when internet connection is lost during a call. and
also another issue when there is call but in early state and connection is
lost. Please help what should I do in all scenarios.
