this will help I've had this problem once and I solved this by adjusting the last xml files before getting the error. Try to check your xml files such that there is no warning or errors in them.

this one helps. Try this...
- The problem here is about the scope of the variable.
code :
for (int i = 1; i <= 15; i++){

        println("F" + i + " = " + fibNumber(i));  // i should be here.

it fixes the issue I assume you have updated ADT with version 22 and R.java file is not getting generated.
If this is the case, then here is the solution:

Does that help you are not calling barprint method properly . it takes two arguments. Replace
code :
barprint( barLength, barSymbols);
static void barprint(int[] barLength, char[] barSymbols) 
    for (int length = 0; length < barLength.length; length++)

    for (int length = 0; length < barSymbols.length; length++)
        System.out.print(barSymbols [length]);
int [] barLength = new int[10];
char [] barSymbols = new char[10];

wish help you to fix your issue Look at the file in question and see what package R is in. If you imported the code to your project, it may be pointing to R in the old package.
For example, I recently copied com.android.HttpAuthenticationDialog into a project. It references R expecting that it com.android is the app's package. Since the project is actually com.example, com.android.R does not exist.
