Locate WebView on phone screen (activity_main.xml)


Drag and drop WebView(Under Composite) on screen in activiy_main.xml which you can find under res > layout > activity_main.xml. You can remove fragment_main.xml file in the folder. Select Theme to Theme.Black.NoTitleBar to remove top bar in order to make WebView takes entire screen.

Adding WebView should create code above on your activity_main.xml file.

Load website on WebView (, enable Javascript and Back button

MainActivity-java file located under src > com.rubstr.rubstr >

Adding splash screen or loading screen


Create a folder called drawable under res folder and add your splash screen image. I created splash screen as 480X800 and named it as splash.png (some reason it does not work with other names).

Next, create a new file called under src > com.rubstr.rubstrnews. Right click on the folder > New > Other > General > File click next and name it Add below code in there.

Note that, if activity_splash text gets red underline, mouse over the cursor for couple seconds to see help text. Select create activity_splash in layout which will add activity into file under gen > com.rubstr.rubstr > Do the same for splash on the bottom of the code.

Next, create new file called activity_splash.xml under res > layout folder. Add below code.

This will add splash image as background on the screen. Make sure you named the image as splash.png in res > drawable folder.
