I need to make a loading bar before opening the address in the WebView. It is blank and can not do with topics found here. You need to load before opening.
Sorry for my English.

if(Build.VERSION.SDK_INT >= 21){

//Check if response is positive
if(resultCode== Activity.RESULT_OK){
if(requestCode == FCR){
if(null == mUMA){
return;
}
if(intent == null){
//Capture Photo if no image available

results = new Uri[]{Uri.parse(mCM)};

I have a splash before ... but what I do not get all white if the page has not yet been charged. I want to show a shipment and then only when you are 100% loaded, display the page. Thanks
