The compile phase doesn't use the AndroidManifest, so we had to specify the
package name on the command line.
We can omit the package name, since we don't resolve external references
in the compile phase. Packages that reference the current package will be encoded
with no package name. When loaded by the link phase, the package name will be supplied
and all the references with no package name will use that one.

Difference between normal app and static library is that
the R file uses non-final fields, and the extra chunks added
by AAPT2 remain in the final APK.
