Anti-theft Vehicle Monitoring and Tracking Android Application Using Firebase as Web Service

The number of vehicle users in Indonesia keep on increasing each year and this triggers probability of criminal activities especially vehicle theft. There were at least 1,688 cases of vehicle theft reported in Aceh Province throughout year 2016. Therefore, it is essentially important to keep vehicles save. One way to do it is by utilising an Android application that is capable to monitor and track the vehicles. This application has a special built-in feature: the ability to locate the position of user's vehicle with the usage of GPS and Google maps. If the vehicle moves from its original position, the application will notify the user and track its new position. Then, the vehicle owner can ask for help from friends and nearby polices. This application was developed using the Agile software methodology. Three tests were conducted for the application. The first test is the functional testing. This test was conducted to ensure that the application works in public and crowded places. The result shows that the application is functioning properly. The second test is the distance accuracy test, tested using altitude and without altitude. The results show that the error rates when altitude is used are 24.24% and 14.94% indoor and outdoor, respectively. When the altitude is not used, the error rates are 26.55% for indoor and 20.55% for outdoor. It is clear that incorporating altitude is more accurate than without using altitude. The last test is the response time between the application and Firebase as web service. We found that the average response time is 2.15 seconds which is considered good for a smartphone application.
