Errors when trying to launch the app

Hi, I've followed along Ben, and I have got the same code, I've checked it, but when I'm trying to launch the app on the emulator, I get these errors:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.tgabor.interactivestory/com.example.tgabor.interactivestory.ui.MainActivity}: android.view.InflateException: Binary XML file line #16: Failed to resolve attribute at index 6: TypedValue{t=0x1d/d=0xff3f51b5 a=2 r=0x7f0b0013}

Hi Gabor,

maybe something wrong with this:

Binary XML file line #16: Failed to resolve attribute at index 6

Look at the line 16 in the XML ...

Let us know what is there wrong

seems the first element under the first line is missing

Look under --> <?xml version="1.0" encoding="utf-8"?> there suppose to be a layout tag.

depends what layout you are using either

"less than symbol" RelativeLayout

or

"less that symbol" LinearLayout

look at your closing tag at the end of the xml file or copy paste the whole file here so we can see.
