Error in Android build in Strings.xml The reference to entity "D" must end with the ';' delimiter

Hi everyone,

I tried doing an Android build of my app, but I get the error “The reference to entity “D” must end with the ‘;’ delimiter”. Referring to the following XML file:

/tmp/109307-android-4157/platformBuilds/standalone_android/app/src/main/res/values/strings.xml

Did anyone experience this before, and would you know how I could get more insight into these buildfiles and what might be lacking?
