Resolve resource values on Android XML parser

[andreban]

The XML parser resolves values that are inlined in the encoded XML. Values that are reference to resources use the format @res/RESOURCE_ID.

We need to parse the resource files the XML depends on and replace the @res/RESOURCE_ID with the correct value.

Example on how the result of a parsing looks today:

  <application
      theme='@res/0x7F0A00CC'
      label='@res/0x7F07006A'
      icon='@res/0x7F030003'
      name='com.example.com'
      allowBackup='true'
      supportsRtl='true'>
