You may have noticed the lack of posts during summer. Partly, that was because I was doing other stuff, for example writing articles and preparing talks. Turns out the articles are published at the same time. The latest issue of German magazine iX contains How to write fast and power saving Android apps and a review of Android Oreo taking a developers' perspective. Please check them out. If you have feedback or want to discuss them please feel free to contact me. I am more than happy to talk.
