Android Logcat & PhoneGap PRO
When developing an hybrid application we encounter difficulties when tried to track (debug) code we wrote in Java Script that is executed inside the WebView object. The problem becomes even more complex when using PhoneGap. The following code sample shows how we can use the android logcat for getting log messages from the code we […]

When the android platform executes our application it will automatically use the correct version in according with the display orientation. The following video clip shows that.

This function receives the ID number of a specific View resource the activity user interface includes. If you ever try to call that function before calling the setContentView function (our activity inherits from the Activity class) then […]
