Question

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 appCompac

Answer 1

It's a bit embarrassing to admit how I've encountered this error, but in a hope to save someone an hour or hair pulling - for me it was a stray ">" that I mistakenly copied into my AndroidManifest:

   
    android:hardwareAccelerated="true"
    android:icon="@mipmap/icon_l"
    android:label="@string/app_name"
    android:requiredForAllUsers="true"
    android:supportsRtl="true"
    android:theme="@style/MyAppTheme">

Too easy to miss if you have a very large manifest - the compiler doesn't complain.
