android - FileProvider - name must not be empty

Remove the android: prefix from the attributes in your paths.xml file. It should look like:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="my_images" path="images/"/>
</paths>

(and you can probably get rid of the xmlns:android bit too, since it's not used, though I have it in one of mine, perhaps because Eclipse put it there when creating the file...)
