Android: drawable resource with numbers. Is it possible?

The reason you can't have a resource with a numeric name is because variable names cannot start with numbers. For each resource, there is a generated constant variable (in R.java) with the resource's name. If you look in your Eclipse project, under the "gen" folder you will see R.java

It is my understanding that it is not possible to have a resource with a pure numeric name in an android project.

If you explain why you require a numeric resource, maybe we can provide alternative solutions
