you can run services in separate processes, but that isn’t arequirement. In fact, unless you specify a process ID explicitly, they won’t.

one golden rule about user interfaces is to always remainresponsive.

When launching your application, Android will spawn a singlesystem process running a single thread of execution.this thread is called the main application thread,
main user interface thread, or UI thread.

Writing code like this may freeze your application—Android can’t continue drawingyour application’s user interface until the download completes because bothdownload and UI code run in the same thread.

Any non-blocking or fast operation is fine to executeon the main application thread that’s running when an application starts. Anythingelse should be executed on a different thread.
