-If you run the app in an Android emulator, the `localhost` parameter points to `10.0.2.2`, rather than `127.0.0.1` as this is the IP address of the host machine. To access the server from a different device on the same network (such as a physical phone) replace `localhost` with the local ip address. You can find the local ip by running `ifconfig` (Linux/MacOS) or `ipconfig` (Windows).
+If you run the app in an Android emulator, use `10.0.2.2` instead of `localhost`, since `10.0.2.2` is the IP address of the host machine from inside the emulator.

-While it's possible to pass binary data through a method call and `ByteData`, it is not the most efficient way to transfer large files. See our [file upload](./file-uploads) interface. The size of a call is by default limited to 512 kB. It's possible to change by adding the `maxRequestSize` to your config files. E.g., this will double the request size to 1 MB:
