In order to send both the file and an arbitrary property or a list of arguments together in one server request, we will use the Multipart feature of the Okhttp library. You may want to limit the number of retries that the OkHttp library makes in case of bad response from server. Create the interceptor for your OkHttp client and set the retry number to something you like. We will set that number to 3 which means that if our client gets response code other that 2xx or 3xx it will retry the request 3 more times.

Remember, the request will be sent in the same form as the original one unless you change it. This may or may not be beneficial for your end goal. Here is the whole code for how to send the file from your Android app to the Java or Groovy server:. In this section we will show how you can receive the file on the server using Java or Groovy. The data from the app will be received by your API Controller and the params arguments will hold all the data.

In order to save the file on server you may use the Spring framework MultipartFile. As we are sending the request in parts, we will need to receive it in parts as well. InvocationTargetException: null Caused by: java. IllegalAccessError: tried to access class org. MultipartException: Could not parse multipart servlet request; nested exception is java.
