Am new to android. I just started studying android and for practicing i created a project "Temperature Converter" under package "de.vogella.android.temperature" and main activity as "ConvertActivity".

On creating project I found errors in 

1. ConvertActivity.java as R.cannot b resolved
2. AndroidManifest.xml file as "the markup in document following the root element must be well formed"
3. no R.java in gen folder

    Just check your XML file also. If you have any mistaken there then, R file cannot be generated. – Chintan Raghwani Jul 30 '12 at 18:27
  • cleaning/rebuilding your project will generate the R file if there are no compile errors. if the R file is still missing after a clean rebuild, open up the Error log and see whats the problem. – Shark Jul 30 '12 at 18:32

Try this it should solve the problem :)

1)run this in a terminal: rm ~/.android/debug.keystore

2)rebuild your project: go to Project –> Clean –> Clean projects selected below –> check your project –> OK

    That's probably something wrong with your AndroidManifest.xml. Double check it and your other xml files and see if there are any errors. – Stark Jul 30 '12 at 18:57
  • i agree with @Stark did you check your xml config file? – Amira Manai Jul 30 '12 at 21:20

Try the following:

  1. Remove the import of the R file.
  2. Then clean the project.
