This class keeps a reference of the application context. In order to use the Mobile SDK, you must first set a valid application context. Alternatively, you can specify the AppContextProvider class in your application's Manifest, as the name attribute of the application element:
<application
android:icon="@drawable/ic_launcher"
android:name="com.kofax.kmc.kut.utilities.AppContextProvider"
android:label="@string/app_name"
android:theme="@style/AppTheme">
</application>
