java.lang.RuntimeException: Your content must have a TabHost whose id attribute is 'android.R.id.tabhost'

Question

I've tried everything to try to get this to work. I am trying to get a tabbed window; I followed a tutorial and made sure every step was correct but every time I load it on to the AVD, it force closes. I am an amateur, so go easy on me! Any and all help will be appreciated.

If I need to provide any other classes associated or xml files, please just ask. I included what I thought was necessary to answer the question. Thanks in advance.

EDIT: Instead of tabs, I've decided to use a main screen with buttons. It's a simple design and I know that it'll work

No solution was found for this. I decided to use a different layout — Joe Michail, Dec 28 '14 at 16:33

Extending TabActivity should be done like below:

TabHost mTabHost = getTabHost();

Note that tabhost is depreciated and it is recommended to use TabLayout with fragments.

Copied the code exactly as it appears and did what the answers said, still nothing. – Joe Michail Jun 25 '14 at 01:54
Didn't solve the problem, but +1 because of answer. Thanks for the help. – Joe Michail Jun 25 '14 at 14:13
