Getting started

git clone --recursive https://github.com/opensciencemap/vtm

Install Android SDK and build-tools 19.0.1. From extras add 'Android Support Library/Repository' and 'Google Repository'. The commands below should set things up correctly when Android SDK is already installed.

export ANDROID_HOME=/path/to/your/android-sdk
export PATH=$PATH:$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools
echo yes | android update sdk --filter platform-tools --no-ui
echo yes | android update sdk --filter android-19 --no-ui
echo yes | android update sdk --filter extra-android-support --no-ui
echo yes | android update sdk --filter extra-android-m2repository --no-ui

Eclipse

./gradlew eclipse
Import all 'vtm' sub-projects into Eclipse.

Android-Studio

Just import build.gradle

Gradle

Or run gradle tasks directly (see also ./gradlew -q tasks):
./gradlew clean install
to build the libraries and add them to the local maven repository.
./gradlew :vtm-android-example:run
to run the android example
./gradlew :vtm-gdx-desktop:run
to run the desktop demo (only Linux64 and Win64 native libs are provided atm)
./gradlew :vtm-gdx-html:jettyDraftWar
to run the webgl demo
