Current Limitation

Using cloud functions to send a file as base64 or byte array can't permit to track uploading progress.

Feature / Enhancement Description

I think could be useful adding the "ProgressCallback" even to the "ParseCloud.callFunctionInBackground" method.

Example Use Case

public static <T> void callFunctionInBackground( @NonNull String name, @NonNull Map<String, ?> params, @NonNull ProgressCallback uploadProgressCallback, @NonNull FunctionCallback<T> callback) { } 

Alternatives / Workarounds

Using REST Api directly with OkHttp or Retrofit
