Vous trouverez à cette adresse, en anglais, ce…

Android library development best practices guide

As Android developers, we are used to having to integrate many libraries in our applications. It can be from quite small .jar files to huge .aar archives which embed multiple screens. Sometimes the integration of these libraries goes smoothly but in some cases, it can be quite painful and lead to the addition of some “hacks” into the app in order to integrate it properly. In some other cases, it can also lead to time-consuming exchanges between the person who integrates the library and the…

Réduire la durée d’un build Android

La durée d’exécution d’un projet est une métrique que tout développeur Android devrait surveiller de près. En effet, même si celui-ci a une grande confiance dans le code qu’il produit, il sera amené à réexécuter le projet plusieurs fois par jour. Lors du développement d’un projet, il est important pour le développeur de pouvoir constater rapidement le résultat de ses modifications. Dans le cas contraire, il peut se produire deux choses : soit le développeur se déconcentre (parce qu’il regarde ses mails par exemple), soit…

Reduce your Android build duration

Build duration is a metric that every Android developer should monitor carefully. Indeed (even if you are very confident in the code you produce), you will have to run your project many times every day. When you re-run your code, you need to be able to see the result of your modifications really quickly. Otherwise, two things may happen: something will distract you and you will loose your focus or you will go back to your code and forget to check the effects of your…

Develop a secured Android application

Android applications are commonly used to process very sensitive data. It is the developer's responsibility to make sure that the information prompted by the user cannot be intercepted easily by a malicious people. The Open Web Application Security Project (OWASP) [9,10] tries to enumerate the potential security issues of a mobile application. Some of them are the system architect's responsibility (such as issues related to weak server sides control), some are the back end developper responsibility (issues related to authentification checks) and finally, some are…
