Android Monitor includes a Network Monitor that makes it possible to track when your application is making network requests. Using this tool, you can monitor how and when your app transfers data, and optimize the underlying code appropriately.
By monitoring the frequency of data transfers, and the amount of data transferred during each connection, you can identify areas of your app that can be made more efficient and use less battery power. Generally, you should look for short spikes that can be delayed, or that could cause a later transfer to be preempted.
Displaying a Running App in the Network Monitor

- Open an app project.
- Run the app on the hardware device.
- Display Android Monitor.
- Click the Monitors tab and display the Network Monitor.
- Enable the Network Monitor by clicking Pause to deselect it.

Connect a hardware device; the Network Monitor doesn't monitor an emulator.
Any network traffic begins to appear in the Network Monitor:
The Network Monitor adds up the amount of time it takes for the device to transmit and receive kilobytes of data. The y-axis is in kilobytes per second. The x-axis starts with seconds, and then minutes and seconds, and so on.
