Unexpected namespace prefix "xmlns" found for tag LinearLayout
I am having an error in following xml file. "Unexpected namespace prefix "xmlns" found for tag LinearLayout". I tried the solutions provided in other similar questions also but it didn't work for me. Same error is occurring in 3 lines where LinearLayout is used.

Answer
Please try following:
Remove xmlns:android="http://schemas.android.com/apk/res/android from all the places excluding the ScrollView. I believe it is sufficient to inform it to the application once and in the outermost Layout or View of the xml file.
