Oracble Visual Builder Cloud Service - Mobile application - Not opening in mobile. Gives blank screen

Oracle Visual Builder Cloud Service (Oracle VBCS) :
I came across a situation, with the mobile application that I developed using oracle visual builder cloud service.

Once I developed the mobile application,I got the apk file after android build. I installed in my mobile (having android verion 5). It opened properly without any problem. Before the application opens, it will redirect to the default vbcs authentication page. Everything went fine.

Later I wanted to do factory reset in my mobile to make it as a brand new one.I did factory reset, then installed my mobile application.Now when I launch the application, it opens with a blank screen and it does not redirect to the visual builder authentication page. What cloud be wrong here?.

Before factory rest, I used "Oracle Max" app. So I wanted to to know whether that application opens properly after factory reset. But that application also did not open and just stuck with a white blank screen.

Now I tried installing my application in another mobile (having android version 6) which also recently had factory reset. There also the same blank screen displays while launching the application.

Ok, So something is missing after the factory reset. What could be that? I checked the google playstore to see if there is any update of the system applications available which could be relevant to this. I updated one applicaiton called "Android System Web View". Once this is updated , my application opened normally as expected. Even Oracle Max app also opened after this update.

Hope this will help someone, who are running into same situation.

Oracle ADF - Table pagination problem from JDeveloper 11.1.1.7

Most of us would have tried to implement pagination on af:table From Jdeveloper 11.1.1.7, pagination feature is directly available for af:table with a property called "scrollPolicy". We need to have two properties in af:table scrollPolicy="page" autoHeightRows="0" Once this is set the pagination feature should be shown.But table pagination does not show up, until unless we have a floating layout around the table. When we try this, we will get a message in the log saying below falling back to scrolling mode since we need parent component to flow and authHeightRows=0 Logs looks as below This is because of the layout around the table. The table should be in a container in flow mode. For example panelGroupLayout or showDetailHeader.

Oracle ADF - Simple Progress indicator or show loading image in custom typeahead / autosuggest

In the last blog Custom Autosuggest / typeahead we saw how to construct a custom typeahead / autosuggest using an input text box and a popup with select items. If the list to be filtered is smaller we wouldn't need to show a loading symbol to the user, while doing the filter process in the backing bean. But what if the the list too big to filter and the filtering process would take some time like 3 to 4 seconds. Or what if the result of search need to be fetched from an external rest end point or from an external soap service ? It would take some considerable amount of time to fetch the data. User's expect some quick response from the page, when they try to do something. So it's better to show them that the process is happening at the back end. A simple way to do that is to have loading gif image ready, and show it when the popup opens and before triggering the server event to filter the list. Once the filtered items are ready and about to be returned to the client then ...
