Hello!

Clarify please, what do you mean under “cannot retrieve data”?
Do you receive an exception? Or server returns empty collection?
Thank you!
Alex

Server returns empty collection. And when I debugged it… I couldn’t pin point what is exactly wrong with it

Put a breakpoint on line “dataQuery.setWhereClause(whereClause);” and copy whereClause value from it to backendless data console. Than enable SQL search and check if the clause is correct.

As I see, it contains date value. Make sure that it’s presented as timestamp in milliseconds, for example, like this: created = ‘1466164440000’

hello Alexandr, i have done all that and yet still it is not retrieving the data

You mean that you’re able to retrieve objects with your where clause through console, but not through android?
