Whenever I run the app, a run-time error crashes the app. This is my log error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.android.practiceset2/com.example.android.practiceset2.MainActivity}: android.view.InflateException: Binary XML file line #63: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference
The error only appears if I draw a grey line between two views using a blank dark grey view of 1dp width in my XML file given below:

I cannot understand how drawing this line is causing an error. Is this the correct way to do this? If not, please suggest a way around it.
