Upcoming Feature: Resource Resolving Mode

[iBotPeaches]

While I think of a better name. While working on #2836 - I realized we need to have some options.

• leave (default) - Resources are left as they are in the application - even if unknown or missing. This will remain default as its more than likely preferred for static analysis.
• dummy - Missing/malformed resources are replaced with a dummy APKTOOL_DUMMY_xxx resources.
• remove - Missing/malformed resources are removed during write-phase.

This would work as follows via an example.

(aapt d resources apk)

      INVALID TYPE CONFIG FOR RESOURCE 0x7f090459

leave (default)

We cannot resolve resource 0x7f090459 so it ends up becoming 0 then casted to @null. This is subject to changing from @null as that was written originally for values and never intended to be a replacement for names. What the true value should be for a named resource whose resource does not exist remains unknown.

  <attr name="actionBarSize" format="dimension">
      <enum name="@null" value="0" />
  </attr>

dummy

We identified that 0x7f090459 was malformed so introduced a dummy resource of proper type in its place.

  <attr name="actionBarSize" formats="dimension">
    <enum name="APKTOOL_DUMMY_0x7f090459" value="0" />
  </attr>

remove

We identified a malformed resource of 0x7f090459 and removed it. This is much easier with child items of arrays and would require further investigation on how well "removing" elements could work depending on the location of the removal.

  <attr name="actionBarSize" formats="dimension"/>
