treat this as a last resort suggestion

i have used blue stacks as a safe way to get at paid for app APKs which amazon in their wisdom, say are incompatible for my fire tablet. ( but A. will send them to blue stacks ok , then I can use backup and restore apps to get the installers ) . i needed lots of help from google to get the amazon & google store apps working in bluestacks, move the apk copies out....
