Add resource id names to the heap dump

[pyricau]

Currently we resolve resource id names at analysis time by calling resources.getResourceEntryName(). This works only if the heap dump is analyzed in the same build as where the heap was dumped.

Instead, we can capture the list of ids and names before the heap dump, store that in a static field in memory, then read it from the analyzer (and clear it in memory)

      for (resId in 0 until (1 shl 16)) {
        try {

          // https://android.googlesource.com/platform/frameworks/base/+/master/core/res/res/values/public.xml
          // 0x07070000 for app, 0x01020000 for Android but we don't need that.
          CanaryLog.d(resources.getResourceEntryName(0x07070000 or resId) + " " + resId)
        } catch (ignored: NotFoundException) {
          // Assumption that might break some day: numbers are sequential, starting at 0
          break
        }
      }

We might want to capture this data as a pre dump step.

Not sure if something changed but this trick doesn't seem to work, I have an app where 0x07070000 doesn't map to any id (cc @romainguy )

It looks like numbers in apps aren't sequential anymore.

Are you saying it doesn't work on Android 10 or in general? There is a pretty new blogpost about this technique https://jebware.com/blog/?p=600

oh cool! It's very possible that I messed up, I'll try again with the code from @Jebstuart
