Hello Pratik,
R.java is an automatically formed class which caches information about resources (such as strings, layouts, colors etc).
R.java basically makes links elements between XML & java; In android, All resources are stored in R.java file
R.java file:
– R.java file is an index into all the resources defined in the directory (res/ ). – This id can be used in the activity source file to perform any action on the component.
– This is particularly powerful with the code-completion features of IDEs like Eclipse & Android Studio because it lets you quickly and interactively locate the specific reference you’re looking for.Regards,
