title: Find out the upload/download speed through android
body: <p>i want to ask that it is possible to find the download/upload speed on android when an application send some data out form the device or receive from outside.if yes than how can we do this. i think one option can be PacketManager API but i am not sure. we can have the ports than listen the ports for traffic and than simple formula for speed. What permission we need for this.(rooted or no rooted permission req)
  thanks</p>
