Odata4j Android - Illegal datetime format

Question

I am encountering the exception stated below in my android code where I am trying to parse an ODATA service using odata4j JAR library.

java.lang.IllegalArgumentException: Illegal datetime format 2015-05-07T00%3A00%3A00

I am getting the error at line below in Android code:

List list = c.getEntities("EntityName").execute().toList();

My entire stacktrace is stated below:

 Caused by: java.lang.IllegalArgumentException: bad valueString [datetime'2015-05-07T00%3A00%3A00'] as part of keyString [*****='*****',*****='0',***='*****',date=datetime'2015-05-07T00%3A00%3A00',*****='*******']
