As you can see, out register link above is set to launch.ltactivity://OpenPage?page=register. This method uses android internal intent communication’s mechanism. By having launch.ltactivity://, we tell android to call whatever activity that listen to it. Since we want our app to do it, we’ll have to catch using intent filter that specified inside manifest.xml:
After this, we just need to read the data sent to LTActivity. For example, for the above URL, when clicked, will go to LTActivity and using the following syntax:
will produce:
