Introduction

We extracted the new Google Maps Library v2 from the "Field Trip" application. It can be used in your own apps as an apklib.

Maps Library v2 has some advantages to the out-dated version v1:

  • 3D view
  • ground overlays/polylines that do not overlap map labels
  • can use Fragments


Prerequisites

smali/baksmali - https://code.google.com/p/smali/downloads/list

dex2jar at least version 0.0.9.11 - http://code.google.com/p/dex2jar/downloads/list

Maven Version 3 - http://maven.apache.org/

FieldTrip.apk - Probably https://play.google.com/store/search?q=com.nianticproject.scout in the US

apktool - https://code.google.com/p/android-apktool/downloads/list

Step 1: Extract library

unzip <fieldtrip.apk> classes.dex

  • extract smalifiles

java -jar baksmali-1.2.7-dev-jar-with-dependencies.jar -o smali-files classes.dex

  • remove support-v4 library

rm -r smali-files/android

  • remove most R*-files

rm smali-files/com/google/maps/R.smali smali-files/com/google/maps/R\$anim.smali smali-files/com/google/maps/R\$array.smali smali-files/com/google/maps/R\$attr.smali smali-files/com/google/maps/R\$bool.smali smali-files/com/google/maps/R\$color.smali smali-files/com/google/maps/R\$dimen.smali smali-files/com/google/maps/R\$drawable.smali smali-files/com/google/maps/R\$id.smali smali-files/com/google/maps/R\$integer.smali smali-files/com/google/maps/R\$layout.smali smali-files/com/google/maps/R\$menu.smali smali-files/com/google/maps/R\$raw.smali smali-files/com/google/maps/R\$string.smali smali-files/com/google/maps/R\$style.smali smali-files/com/google/maps/R\$xml.smali

  • re-assemble smali files

java -jar smali-1.4.0.jar -x -a 9 smali-files/ -o mapfragment.dex

  • make classes jar from dexfile

dex2jar-0.0.9.11/d2j-dex2jar.sh mapfragment.dex --force

  • install jar to local maven repository

mvn install:install-file -DgroupId=de.schildbach.maps -DartifactId=maps-v2 -Dversion=1.0-SNAPSHOT -Dpackaging=jar -Dfile=mapfragment-dex2jar.jar Step 2: Make apklib

  • Extract resources with apktool

apktool d <fieldtrip.apk> fieldtrip

  • copy the following resources from fieldtrip

Make an apklib from the resourcses and insert maps-v2 lib from above as a dependency.
