Note: Issue tracking for this repo has been disabled. Please use the main Appium issue tracker instead.


npm install appium-uiautomator2-driver


Import Android Driver, set desired capabilities and create a session:

import { AndroidUiautomator2Driver } from `appium-uiautomator2-driver`

let defaultCaps = {
  app: 'path/to/your.apk',
  deviceName: 'Android',
  platformName: 'Android',
  automationName: 'uiautomator2'

let driver = new AndroidUiautomator2Driver();
await driver.createSession(defaultCaps);

Specifying and selecting devices/emulators

The driver will attempt to connect to a device/emulator based on these properties in the desiredCapabilities object:

  1. avd: Launch or connect to the emulator with the given name.
  2. udid: Connect to the device with the given UDID.
  3. platformVersion: Connect to the first device or active emulator whose OS begins with the desired OS. This means platformVersion: 5 will take the first 5x device from the output of adb devices if there are multiple available.

If none of these capabilities are given, the driver will connect to the first device or active emulator returned from the output of adb devices.

If more than one of these capabilities are given, the driver will only use first the capability in the order above. That is, avd takes priority over udid, which takes priority over platformVersion.

Custom binaries url

To use a mirror of the UIAutomator 2 driver binaries use npm config property uiautomator2_driver_cdnurl. Default is

npm install appium-uiautomator2-driver --uiautomator2_driver_cdnurl=

Or add the property into your .npmrc file.


Another option is to use PATH variable UIAUTOMATOR2_DRIVER_CDNURL.

UIAUTOMATOR2_DRIVER_CDNURL= npm install appium-uiautomator2-driver

API Notes

lock behaves differently in Android than it does in iOS. In Android it does not take any arguments, and locks the screen and returns immediately.
