Essential Bada Interview Questions & Answers:

1. How to upgrade my firmware?

You can upgrade your firmware by connecting your phone to Kies.

2. Can you please explain what kind of options are available to integrate ads within an application in bada 2.0?

The Ad control supports two types of Ads: Image Banner, and Text Banner. When the user touches the Ad, one of the following actions is triggered:

Click-to-Brower: Opens a web page, set by the advertiser, in the default browser.
Click-to-Call: Automatically dials a number set by the advertiser
Click-to-Store: Launches Samsung Apps Store with the product page defined by the advertiser.

For more info, refer to the Osp::Ads::Controls namespace in the help file.

3. How to load a local HTML file on the device with a Web control?

Samsung bada currently supports the "/Home" virtual path, which is readable and writable, as well as the "/Res" virtual path, which is readable for loading local HTML files. Make sure to store local HTML files in the Home or Res folder as per your (reading and writing) requirements, and specify the file path as "/Home/ .html" or "/Res/ .html".
