Try to make a new project and add just a cube or so and build the android apk with it, if it works then its something else but if it cant be built then you have a problem with the android sdk, i suggest you install again manually downloading all the needed components, I have fought this long time each time i had same issue and its hard to know how to fix really but its about installing again maybe from different source not just official android site but other people, there are people who found same issue and post the dk version that worked for them or so
