Detecting Mobile Network Performance (Android)

We are looking for help in detecting mobile network performance on unrooted Android phones, especially those running Jellybean. Although we would consider detailed instructions, we are looking for a workable demo or code that allows us to be able to attach to the phone process and use reflection to call methods relating to [login to view URL] (in any unrooted Jellybean). And not only return null (return live). So basically detect all disconnects and their reasons. An agreement must be signed to confirm that all demos and code will become our property to release payment.
