/*
Android Apps are built with -buildmode=c-shared. They are loaded by a
running Java process.
Before any entry point is reached, a global constructor initializes the
Go runtime, calling all Go init functions. All cgo calls will block
until this is complete. Next JNI_OnLoad is called. When that is
complete, one of two entry points is called.
All-Go apps built using NativeActivity enter at ANativeActivity_onCreate.
Go libraries (for example, those built with gomobile bind) do not use
the app package initialization.
