In this thesis we analyze the concepts of dependability and dependable systems. We investigate methods of designing and implementing dependable systems, in general, and on the Android operating system. A literature review was carried out with two main goals. Firstly, to gain and be able to spread knowledge of dependability according to both its qualitative and quantitative definitions. Secondly, to prove our theory that there is a lack of information regarding dependable systems on Android, establishing a need for this thesis. We then attempt to apply our newly acquired knowledge in a case study, where we design and implement a dependable system, in the form of a security camera application, on Android. This gives further insight into the challenges of designing dependable systems, and through our experience we learn how to overcome these challenges. While the scope was too large to fully cover every aspect of dependability, we gained valuable knowledge that is presented in this thesis
