Feature description

currently, if you git clone CodeOnTheGo and open the project in android studio, you will see that it targets v7 debug variant by default. This makes it an issue that when opening a project it will take some time thinking a variant that you don't even use and either ways you can't get to be finished building unless you edit some files the notice is LLAMACPP which currently doesn't build on v7 variants. Even if you set it to V8, if you close Android Studio and reopen the project again it return to V7. The default variant should be set to V8 DEBUG so we can get started directly coding debugging and building without waiting for something that we don't use.

Use Case

v8 has support for all app features, unlike v7 witch doesn't support building llamacpp, v8 should be the default variant to speed up the development.

Benefits

getting the project to sync diractly to v8, with out waiting for the v7 sync witch may not needed at all
