Is it possible you could share the xml file? Diff-Cover is looking for lines with the xml attribute "line-rate" If you are hitting this error its a sign that the tool did not find any of these lines.

Can this tool generate the android diff coverage ? I use jacoco generate the android coverage, somebody said that this tool coud not use in android.

If you can create a jacoco it should in theory work with diff cover. The tool was originally written with python in mind so its possible some assumption was made that wont work for android. But I cant imagine what that would be off the top of my head
