Install respective sdks. Watch sdk is 2.3.2 (check the files to verify) If using android emulator, ensure resolution is 1080 x 2340 pixels, or a similar aspect ratio
The watch app & android app communicate through protobuf.
The watch app in particular uses Nanopb.
Use the Nanopb binary to compile .proto files in C. (see the readme at github for more info)
Things to note:
Both watch app & android app use the same *.proto files.
*.proto files should be symlinked from AndroidApp to WatchApp.
Watch app's *.proto needs extra configuration if the *.proto includes variable length fields
like strings, bytes or repeated fields.
Specify the max number of repetitions, or max size in an accompanying *.options file.
Do not forget to edit the *.options file when editing the *.proto files
The android app is a producer, while the watch app is a consumer under Samsung's terminology. This distinction is found in the code for inter-device communication. See Samsung's official programming guide for more info.
