11,958 PointsErrors 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:

7,806 Pointsseems 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.

11,958 PointsWhat should stand there?
Mazen Halawi
7,806 Pointsdepends 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.

11,958 PointsI checked it, and it is in my code but somehow I didn't include it in my code
Mazen Halawi
7,806 Pointswe cant guess how your code is going you need to supply more information. kindly paste the full code of the affected layout.

10,365 PointsHi 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
