Gradle build system and Android Studio

[mobileorg-android on behalf of Henning Weiss]

Hi all,

the new build system should now work without a hitch with Android Studio or
from command line. I updated the HACKING.md file to reflect that. If you
had problems building mobileorg I would encourage you to try again with a
new clone. Remember to update Android Studio and the Android SDK tools to
their newest versions and install Android SDK 19.0.1.

happy hacking,
Henning

Hi,

Android Studio 0.5.8 complains about the gradle configuration stating the
project is using an unsupported version of the gradle plugin (0.7.3)

### start dump
Error:The project is using an unsupported version of the Android Gradle
plug-in (0.7.3).

Version 0.9.0 introduced incompatible changes in the build language.
Please read the migration guide to learn how to update your project.
<a href="fixGradleElements">Open migration guide, fix plug-in version and
re-import project</a>
### end dump

If i change the dependency to

dependencies {
classpath 'com.android.tools.build:gradle:0.9.0'
}

it complains about the wrong gradle version.

Do i have to replace the gradle wrapper with a newer version to fix this,
or is there another way?

Thanks,

Sebastian
