android-sensor-injection

Small middleware written as part of research into emulation detection. This functions similarly (according to their docs) to genymotions Device Link feature that lets you stream a real device's sensor data connected over ADB's into the emulators sensor data. Since Android studios emulator doesn't support this natively I wrote this up.

This uses SensorServer to stream live sensor data over adb and then feeds the data into the emulator using the android emulator console.

pre-requisites

• ADB and other android tools
• Install SensorServer on your android device and enable the local host option in the app.
• python environment set up with websocket-client installed

usage

• start the SensorServer app on your phone and start the server
• run adb forward tcp:8080 tcp:8080 on your machine that the device is connected to over USB
• start your emulator(s) and keep note of the port number (usually defaults to 5554)
• if this is your first time connecting to the emulators console, I would first run telnet localhost <emulatorport> and then make sure to delete the data in auth token located in .emulator_console_auth_token so that it's empty. Since this script doesn't support connecting with an auth token that is mandatory.
• run python sensorinject.py --port <emulator-port> and you should be streaming data! you can drop the --port <emulator-port> option if your port is 5554 since that is the default in the script.

NOTE: Since my device didn't support gyroscope, I fed in the android.sensor.gravity sensor. You can modify the script depending on what sensors you do/don't have.
