I'm following this tutorial from the Tizen developers website.
I cannot understand where exactly to put the code snippets being discussed. From how the tutorial was presented they don't really tell you which code goes where. Been at it for days now.
How should the final .c file look like exactly?
Can someone help?
Please check the below code that will help you to understand a Complete Native Webview example:
