Go back to previous screen on SslErrorHandler

So in my webview, I am showing an error dialog box for SSL security issues which Google had made compulsory. The code looks like below:

@Override
public void onReceivedSslError(WebView view, final SslErrorHandler handler, SslError error)
{
final AlertDialog.Builder builder = new AlertDialog.Builder(LaunchWVActivity.this);
builder.setMessage("SSL cert is invalid.Install a valid certificate or click continue to proceed.");
builder.setPositiveButton("continue", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
handler.proceed();
}
});
builder.setNegativeButton("cancel", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
handler.cancel();
}
});
final AlertDialog dialog = builder.create();
dialog.show();
}


When a use clicks cancel, my webview just stays on the same screen with white screen. I want to navigate user to previous screen from where he came from. I have tried adding a onCancelListener, but it has not worked.

cancel

onCancelListener

Something like this

dialog.setCancelable(true);
dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
// dialog dismiss without button press
Log.d(TAG,"Cancel pressed");
webview.goBack();
}});


What am I missing here?

The question is widely applicable to a large audience. A detailed canonical answer is required to address all the concerns.

I resolved this issue. It was very straight forward approach with finishing the current activity. Initially I didn't realize, I could have my current activity as globally declared.

builder.setNegativeButton("cancel", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
handler.cancel();
currentActivity.finish();
}
});
