java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity. titanium

I'm creating a custom theme for my Titanium application using this theme generator. But when I run my application it's crashing and my log says that I need appCompact even if I set the theme for sdk > sdk 11.

And my targeting Android version is API 19 and min SDK version is API14, so I wonder why I need appCompact.

This is what my log says:

ok please try this,

Add this attribute to your activity

android:theme="@style/Theme.AppCompat"

You are using an ActionBarActivity, which requires an AppCompat theme. I'm not sure how you'd do this with Titanium, but you'd either need to switch to an AppCompat theme or use a regular Activity (which shouldn't be a problem if you're targeting 11 or above).

write the code in style-v11 folder

 name="AppBaseTheme" parent="Theme.AppCompat.Light"  

and in styles-v14 folder

 name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar"

Delete all the styles in the library project. Specify Style folder only in main project not in library project. It worked for me :)

Simply change the ActionBarActivity to Activity or FragmentActivity
