what is the procedure for generating R.java in android Eclipse juno

Question

I have installed eclipse juno and also added the plugin's of the android sdk. After installing android SDK manager, I've created a new android project, but a problem arises in R.java file. R.java doesn't open. Please give me a solution. I am new to android.

Answer 1

Ensure the code, resources and AndroidManifest.xml do not have any problem.

First, delete the R.java file. As soon as you delete, that file should be re-generated automatically if you have enabled automatic build (Project->Build Automatically).

If that doesn't work try to clean the project by clicking on Project->Clean.

If it still doesn't work then, confirm you have android sdk build tools installed. For this, open Android SDK Manager and ensure Android SDK Build-tools has the status of Installed.

Also confirm that the ADT is up-to-date. To update ADT, in eclipse go to: Help -> Check for updates. Select the necessary entries like: Android Development Tools and update them.

Hopefully one of these solutions will solve your problems :-).
