We developped the Android-Hooker tool to collect and analyze huge quantity of information produced by multiple monitored applications. To archive and search effectively in this large amount of data, we store events in an ElasticSearch database (see elasticsearch.org). To insert and update these events in the database, we rely on the elaticsearch python module (see elasticsearch-py). In effect, its the hooker-common subproject that requires this dependency. This error happens if this dependency is not installed. The following command should install the mandatory python package:

 $ cd hooker_common
 $ sudo python setup.py install
