Abstract :
The Web Service is generally used to perform data services between
different platforms such as Web and mobile applications. Existing and growing
Web service is ReST API and SOAP. In this study conducted a comparison
between Web service ReST API and SOAP in providing data service for Android based client application. Data retrieval testing is performed on smartphone
devices with different specifications. The tested data is divided into 2, i.e. data of
the same size format and data in different size formats. The test is divided into 3
stages, the first one tested with 10 data, to two 20 data, and the three 30 data, by
loading data from each of the compared Web services. From the test results the
results were obtained that testing with the same data size format did not make the
data synchronization time as well. From the results the overall test was obtained
that the ReST API was running faster than SOAP. With the sum of the entire
average time synchronization data on a different device with the same size format
on the ReST API it generates 3.4 seconds and SOAP generates time 3.9 seconds.
While syncing of data on different devices with different size formats on the ReST
API gets 4.7 seconds and SOAP gets time 5.3 seconds. The ReST API Web Service
technology and Web service SOAP technology can be implemented in the Android
client application with the minimum version of Android Lollipop 5.0.1.
