I have been developing my app for a couple of weeks, routinely rebuilding without errors. Then something weird happened to my Windows system. It's as if all my Android Studio settings have been lost. Normally, when I start Android Studio, it automatically loads my project. Today it didn't and I had to open the project manually. I then tried to open one of my layout XML files and it refused to render it saying "Android N requires the IDE to be running with Java 1.8". I remembered I had this problem before. I clicked on the little green man with a 24 next to him and chose "API 23: Android API 23". Problem solved. I can now see my activity layout. Except... Unfortunately, if I now close Android Studio and re-open it, it forgets that I selected API 23 and again says "Android N requires..." and I have to explicitly choose API 23 again. Why isn't it remembering like it used to? However, that's a mere inconvenience compared with the other problem. Now, when I try to rebuild my app I get the error "compileSdkVersion 'Android-24' requires JDK 1.8 or later to compile." It wasn't saying that yesterday. What's gone wrong? How do I convince Android Studio, permanently, that I want to use API 23 and not 24 for rendering and how do I fix the compilation error? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
