+### Accessing the f API using adb
+
+If you want to access the f API on your computer, but don't have a local network to access your Android device. You can connect your Android device to your computer with a cable and then use adb to expose the f API to your computer.

+```
+$ adb devices
+List of devices attached
+Your_device_or_avd_name     device
+
+$ adb -s Your_device_or_avd_name forward tcp:9000 tcp:9000
