Deleting buffer cache for IO throughput

We are writing an application to measure throughput speed of SD card
on ARM-based Android target using Java APIs.

When we execute the application twice for read operation, results are
seen to be affected with buffer cache.

For example, first read throughput is 275 KBps and second read
throughput is 350KBps.

Application is simple Java-based application, it is .jar app. It is
not using the Application class  and hence, not having
AndroidManifest.xml present. ().

Is there any way to clear the buffer cache after each run of the
application ?

Thanks and Regards,
