I dont know where the error is as it is not showing the cause in log file. can anyone help me with this please?
La solution
If you use the fragment tag in the layout then point the fragment's class using the class attribute:
<fragment
android:id="@+id/bink_fragment"
class="com.example.iolcalci.Binkhorst_x"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
