Here is a screen capture of two SVG I exported from Corel and viewed on a browser. Nothing really special.
We need to see the code.
The one on the left is a series of blocks with red fill and the one on the right is a path with a description of how to render the dashed stroke. We can see that in the generated code. I am only posting the path tag. There are a bunch of numbers but you can see the difference on the initial attributes of the file. (You can use them to reconstruct the examples)

So the two options, a path with a special stroke, and a series of blocks are exported as such.
My first thought would be that your render engine on Android is not capable of rendering the file, I used SVG version 1.
Answering your specific question, if what you have is a single curve, there is nothing to break apart, you have only one connected curve. What I did was convert the path to objects.
- Object > Convert Stroke to object
- Or press Ctrl+Shift+Q
Now you have several blocks not connected. Now you can brake those apart.
