Unable to add custom dialog on onBackButton if customBrowserConfig.setDisableBackButtonDialog(true) set true

[kedia1307]

I am trying very hard to add my app's custom dialog if a user presses the back button from CBActivity.
As per your document
onBackButton(AlertDialog.Builder alertDialogBuilder) - This callback provides alert dialog access, so customisation can be done to alert dialog.
But In your CBActivityI can find that you are finishing activity if customBrowserConfig.setDisableBackButtonDialog(true) is set true. whic ofcourse finishes the activity and I am not able to add my custom dialog.
Please help.

It should work fine if you remove finish from your CBActivity.
//following code is from CBActivity(unEditable)
@OverRide
public void onBackPressed() {
if (customBrowserConfig != null && customBrowserConfig.getDisableBackButtonDialog() != 1) {
payUCustomBrowser.addEventAnalytics(CBAnalyticsConstant.USER_INPUT, CBAnalyticsConstant.PAYU_BACK_BUTTON_CLICK.toLowerCase());
payUCustomBrowser.showBackButtonDialog();
} else {
payUCustomBrowser.addEventAnalytics(CBAnalyticsConstant.USER_INPUT, CBAnalyticsConstant.MERCHANT_BACK_BUTTON_CLICK);
if (CustomBrowserData.SINGLETON.getPayuCustomBrowserCallback() != null)
CustomBrowserData.SINGLETON.getPayuCustomBrowserCallback().onBackButton(null);
CBActivity.this.finish();
}
}
