Error building release APK

Question

today I wanted to build my application's release APK but AS didn't want to do this for me. It says:

Error:Execution failed for task ':mergeDebugResources'. Unsupported type 'TextView' in file C:\\Users\\Sven\\workspace\\Soest\\res\\layoutlarge\\kontakt_form_wiese.xml

That's all the Information I can find. Can you help me? I have to finish this project today and this is totally blowing me Off-Course...

UPDATE I just found out that Android Studio doesn't find the R.styleable.TextView in TextView.java. But I don't know why and until today everything worked fine...

It happens only when modifying the XML files on the project. If you rebuild the entire project before running (Build > Rebuild Project) it doesn't show up anymore.
