I have implemented a specific auto backup rules for my app following the developers documentations :
Here , they specify that you can configure this and attach it to your manifest
<full-backup-content>
<include domain=["file" | "database" | "sharedpref" | "external" | "root"] path="string" />
<exclude domain=["file" | "database" | "sharedpref" | "external" | "root"] path="string" />
</full-backup-content>
So I've created a new XML as the documentation said , and then I've pasted the example into my xml . However , the same example provided in the documentation doesn't compile at all :
error: not well-formed (invalid token).
How can I fix this ?
