Android Question Error with ActionBar after 7.8 upgrade

[dealsmonkey]

Hi All and happy New Year.

I have done an upgrade to V 7.80 and am now getting the following error on compile. Any advice, please.

In my code, I am using #Extends: android.support.v7.app.ActionBarActivity


error: cannot find symbol
public class main extends android.support.v7.app.ActionBarActivity implements B4AActivity{
^
symbol: class ActionBarActivity
location: package android.support.v7.app

Are you using the latest version of AppCompat?

Please try to extend from: android.support.v7.app.AppCompatActivity

android.support.v7.app.ActionBarActivity is deprecated since 2015 and maybe they have removed it from the latest Support library (though I haven't found a notice about it in the changelogs)

Sorry for the late reply. making this change has allowed me to compile, getting some null object errors now, so will look into these !!

Try to load the layout in the designer and save it. Now compile and try again.
