4554  *
4555  * This primarily handles the issue of private/public attribute clashes
4556  * in framework resources.
4557  *
4558  * AAPT has traditionally assigned resource IDs to public attributes,
4559  * and then followed those public definitions with private attributes.
4560  *
4561  * --- PUBLIC ---
4562  * | 0x01010234 | attr/color
4563  * | 0x01010235 | attr/background
4564  *
4565  * --- PRIVATE ---
4566  * | 0x01010236 | attr/secret
4567  * | 0x01010237 | attr/shhh
4568  *
4569  * Each release, when attributes are added, they take the place of the private
4570  * attributes and the private attributes are shifted down again.
4571  *
4572  * --- PUBLIC ---
4573  * | 0x01010234 | attr/color
4574  * | 0x01010235 | attr/background
4575  * | 0x01010236 | attr/shinyNewAttr
4576  * | 0x01010237 | attr/highlyValuedFeature
4577  *
4578  * --- PRIVATE ---
4579  * | 0x01010238 | attr/secret
4580  * | 0x01010239 | attr/shhh
4581  *
4582  * Platform code may look for private attributes set in a theme. If an app
4583  * compiled against a newer version of the platform uses a new public
4584  * attribute that happens to have the same ID as the private attribute
4585  * the older platform is expecting, then the behavior is undefined.
4586  *
4587  * We get around this by detecting any newly defined attributes (in L),
4588  * copy the resource into a -v21 qualified resource, and delete the
4589  * attribute from the original resource. This ensures that older platforms
4590  * don't see the new attribute, but when running on L+ platforms, the
4591  * attribute will be respected.
