This is a combination of three minor clean-up tasks:
- Generate correct idmap even if name lookup fails:
Any resources following a resource with a spec but no actual values
would receive an incorrect ID in the idmap due to an accumulating offset
error. To combat this, a dummy value is inserted in the idmap whenever
a resource with a spec but no values is encountered.
- Optimize pruning of padding zeroes in idmaps:
Earlier, trailing zeroes were iteratively popped from the end of each
type block of an idmap. This commit instead tracks where to make the
cut, and does so with a single function call.
- aapt: warn about resources which lack values:
The resource framework assumes every resource to have a value for
at least one valid configuration. However, if multiple resource
directories are used (several -S options to aapt), the list of
configurations is limited by dpi (-c option to aapt) and a resource
is only available in discarded dpi configurations, aapt will create
a resource entry where each configuration lack an actual value. This
commit lets aapt emit a warning whenever this has happened.
