how to consume Odata Service from Android using any library that contain select where statement

Question

Is there a way to consume Odata Service from Android using Odata4j or any other library that contain SELECT WHERE Clause statement

I searched a lot but can't find any solution

Answer 1

For odata4j you need to instantiate a ODataConsumer Object - let's call it consumer. With this object you are able to perform any desired database actions. For example:

OEntity result = consumer.getEntities("YourEntityName").filter("Field2 eq 'xyz'").select("Field1, Field2, Field3").execute();

This would resemble the following SQL query

SELECT Field1, Field2, Field3 FROM YourEntityName WHERE Field2 = 'xyz'

For more information regarding the string arguments for filter() and select() you should have a look into the odata documentation at odata.org -> URI conventions.

If you want to understand the java functions of odata4j use the documentation at odata4j documentation .

I can also recommend the odata4j example files .

Nice question......

We can access the odata service by using AsyncHttpClient in android.

Here we need to override some methods ,and its taking RequestParams as a parameter will return data as json or xml.

you can read more on AsyncHttpClient Here : http://loopj.com/android-async-http/

here we can pass RequestParams,it will take select as key and query as your original query. try it and let me know if you have any issues
