Class.forName("com.payu.custombrowser.Bank"); final MyBank bank = new MyBank() { @Override public void registerBroadcast(BroadcastReceiver broadcastReceiver, IntentFilter filter) { mReceiver = broadcastReceiver; getActivity().registerReceiver(broadcastReceiver, filter); }

            @Override
            public void unregisterBroadcast(BroadcastReceiver broadcastReceiver) {
                if (mReceiver != null) {
                    getActivity().unregisterReceiver(mReceiver);
                    mReceiver = null;
                }
            }

            @Override
            public void onHelpUnavailable() {
                getActivity().findViewById(R.id.parent).setVisibility(View.GONE);
                getActivity().findViewById(R.id.trans_overlay).setVisibility(View.GONE);
            }

            @Override
            public void onBankError() {
                getActivity().findViewById(R.id.parent).setVisibility(View.GONE);
                getActivity().findViewById(R.id.trans_overlay).setVisibility(View.GONE);
            }

            @Override
            public void onHelpAvailable() {
                getActivity().findViewById(R.id.parent).setVisibility(View.VISIBLE);
            }
        };

public static class MyBank extends Bank{ @Override public void registerBroadcast(BroadcastReceiver broadcastReceiver, IntentFilter filter) { mReceiver = broadcastReceiver; getActivity().registerReceiver(broadcastReceiver, filter); }

@Override
public void unregisterBroadcast(BroadcastReceiver broadcastReceiver) {
    if (mReceiver != null) {
        getActivity().unregisterReceiver(mReceiver);
        mReceiver = null;
    }
}

@Override
public void onHelpUnavailable() {
    getActivity().findViewById(R.id.parent).setVisibility(View.GONE);
    getActivity().findViewById(R.id.trans_overlay).setVisibility(View.GONE);
}

@Override
public void onBankError() {
    getActivity().findViewById(R.id.parent).setVisibility(View.GONE);
    getActivity().findViewById(R.id.trans_overlay).setVisibility(View.GONE);
}

@Override
public void onHelpAvailable() {
    getActivity().findViewById(R.id.parent).setVisibility(View.VISIBLE);
}

}

Yes, I am facing the same issue.

[betaCode95]

Is there a fix for this issue?

[DhavalsShah]

Yeah, there is fix for this issue. I removed the BankFragment code from the SdkWebViewActivityNew.java and migrate BankFragment code as a new class and made changes appropriately in SdkWebViewActivityNew.java in order to access BankFragment object. I hope this will help you.

import android.content.BroadcastReceiver;
import android.content.IntentFilter;
import android.view.View;

import com.payUMoney.sdk.R;
import com.payu.custombrowser.Bank;

public  class BankFragment extends Bank{
    BroadcastReceiver mReceiver;
    @Override
    public void registerBroadcast(BroadcastReceiver broadcastReceiver, IntentFilter filter) {
        mReceiver = broadcastReceiver;
        getActivity().registerReceiver(broadcastReceiver, filter);
    }

    @Override
    public void unregisterBroadcast(BroadcastReceiver broadcastReceiver) {
        if (mReceiver != null) {
            getActivity().unregisterReceiver(mReceiver);
            mReceiver = null;
        }
    }

    @Override
    public void onHelpUnavailable() {
        getActivity().findViewById(R.id.parent).setVisibility(View.GONE);
        getActivity().findViewById(R.id.trans_overlay).setVisibility(View.GONE);
    }

    @Override
    public void onBankError() {
        getActivity().findViewById(R.id.parent).setVisibility(View.GONE);
        getActivity().findViewById(R.id.trans_overlay).setVisibility(View.GONE);
    }

    @Override
    public void onHelpAvailable() {
        getActivity().findViewById(R.id.parent).setVisibility(View.VISIBLE);
    }

}
