Answer 1

Resource name must start with a small case letter or an underscore('_'). For more rules regarding resource naming convention, you can refer to the below-mentioned medium article. https://medium.com/@AkhilDad/a-designers-guide-for-naming-android-assets-f790359d11e5

Answer 2

Resource name must start with letter. You can't start image name with digits.

The reason you can't have a resource with a numeric name is because variable names cannot start with numbers.

Answer 3

There are a few conventions used in resources:

1. For resources that exist as separate files, they must be lower_case_underscore_separated. The appt tool makes sure that your files are only lower-case, because using mixed case can cause issues on case-insensitive filesystems.
2. For resources declared only in values/... (attributes, strings, etc) the convention is generally mixedCase.
3. There is a convention used sometimes to tag names with a "classification" to have simple namespaces. This is for example where you see things like layout_width and layout_alignLeft. In a layout file the attributes for both the View and the parent layout management are mixed together, even though they are different owners. The "layout_*" convention ensures that there are no conflicts between these names and it is easy to understand which entity the name impacts.

Answer 4

The error is actually because the resource name cannot start with a number. Resource name should start with a letter or underscore(_).
