Please note this is NOT the official volley project, it is just a restructure of the official one that uses maven.
Want to use the real one ?
git clone https://android.googlesource.com/platform/frameworks/volley
Clone it and run mvn clean install.
The build runs instrumentation tests by default, you need to have a device attached… you can of course set up an emulator to start before the tests.
It will install locally the jar that you can then use in your pom with this dependency tag
<groupId>com.android</groupId>
<artifactId>volley</artifactId>
<version>1.0-SNAPSHOT</version>
I will delete the project as soon as a better and official way to share the library is available. If you know please let me know :)
