It's complaining about the attribute tools:context=".MainActivity" that is part of the <LinearLayout> tag. It doesn't know what the tools: prefix means.

You need to add xmlns:tools="http://schemas.android.com/tools" as an attribute to the <ScrollView> tag. Alternatively, get rid of the tools:context attribute for the <LinearLayout> tag.

The tools:context (as well as other tools:... attributes) are used as part of Android's lint checking of XML files. See here for more info.
