I'm developing an android application for a month. and today when I cleaned my project (project>clean...), I got "R cannot be resolved to a variable" error and i can't run my app.

I Googled for solution and did every solution for this problem but not success.

Note: I removed all imports R and cleaned my project again but the problem exists.

Can anyone help me?

Sorry for bad English!

Edit: problem solved. there was some errors in one of xml files.

  • Do you have any other problems/errors in your project? Try to fix them, these can prevent the R file from generating. (Also, you need to import your own R, like com.myapp.example.R) – nhaarman Aug 01 '11 at 11:47
  • right click on the project and click buildpath – Randroid Aug 01 '11 at 11:48

this appears when you have errors in layout files or other xml files. Also take care that images have names that don t contain upper caracters

I solved my problem 

LinearLayout android:id="@id/TelNoLayout"

replace to 

LinearLayout android:id="@+id/TelNoLayout"

and build
