Using the singleton pattern Android

No comments

We have three services writing to the SQLite in the NOxDROID android app. 

  1. NOxDroidIOIOThread
  2. Location tracking
  3. NOxDroidService
We let them share a singleton databaseadapter to avoid any concurrency problems with regard to database access. It is implemented so the application class has a method which returns the shared databaseadapter. 
For a more comprehensive example with code see this blogpost at

We did a video scenario of the use of NOxDROID using a simple paper prototype. The purpose of the scenario is to convey the general idea of the project and the context in which NOxDROID can be used. Preliminary mockups of the interface is also a part of the visualization of the scenario.

Making sense of sensing

No comments

Stine had a meeting Friday at COWI (a Danish Engineering Consultancy Company) about sensing air pollution. Some problems with our current project proposal arose. 

O3, temperature and NO2 are important factors in air pollution. 

It is a bit unclear whether the sensor we have ordered (MQ-135) is actually able to detect NO2. The data-sheet is not very specific, only refering the to general category of nitrogen oxides, NOx. 

Another project, AIR ( very similar to ours used sensors from citytech, so possibly we have to change the type of sensor we are going to use.

COWI suggested to contact FORCE and DMU
