ZIP file must contain application, softdevice or bootloader

Hello, I'm building an Android application for DFU. I have a zip file and am downloading it and getting the content URI after download and using it in starter.setZip(contentUri). But I am getting this exception:

11-09 18:52:58.492 31020-31090/com.example.nikitha.run_2 E/DfuBaseService: An exception occurred while calculating file size

Hi,

What do you have in your .zip file ? How did you create it ?

Seems like the DFU app detecting that it should have softdevice + application + bootloader.

The zip file contains a manifest.json, a bin and dat file. ArchiveInputStream is reading from the contentURI so it is not null. Not sure why the error persists.

Yeah, but how did you generate that .zip file. What inside that manifest.json or .dat, will tell the DFU library what to expect.

The file is read properly and update happens when I do it via the Nordic app. This is the error I get when I'm adding the DFU library to my app and trying to update.

In ArchiveInputStream, this ze is null. ZipEntry ze; while ((ze = getNextEntry()) != null) { final String filename = ze.getName();

I got a report from our app team that you have managed to solve the problem. Would you mind to give an update here on how you fixed it?
