With the use of the uiautomator2 library and the Android Debug Bridge (ADB), we can automate various tasks on an Android device from a computer.

The uiautomator2 library provides a Python wrapper for controlling the mobile device and is based on the Uiautomator2 testing framework. openatx/uiautomator2

In this post, we will delve into the basics of using uiautomator2 and ADB to perform tasks such as getting the current activity and performing a press action. We will explore the power and ease of using these tools to streamline and automate tasks on an Android device.

Install

pip3 install uiautomator2

Usage

import uiautomator2 as u2

d = u2.connect() # connect to device
print(d.info)
# {'currentPackageName': 'net.oneplus.launcher', 'displayHeight': 1920, 'displayRotation': 0, 'displaySizeDpX': 411, 'displaySizeDpY': 731, 'displayWidth': 1080, 'productName': 'OnePlus5', 'screenOn': True, 'sdkInt': 27, 'naturalOrientation': True}

What can I do with it?

• Install an app
• Launch an app
• Stop an app
• Stop all running apps
• Get app info
• List all running apps
• Push and pull files
• Retrieve the device info
• Take a screenshot
• Get the current activity
• Key Events
• Perform a swipe / scroll / pinch / zoom / press actions
• and much more…

Example

In this example, I will show you how to like a user on the Muzmatch app.

import uiautomator2 as u2
d = u2.connect()  # connect to device

def like_user():
    like_btn = d.xpath(
        '//android.widget.Button[@resource-id="com.muzmatch.muzmatchapp:id/discoverLikeButton"]').all()
    # check if the button exists
    if like_btn:
        like_btn[0].click()
    else:
        # sleep for 5 seconds
        d.sleep(5)
        btns = d.xpath('//android.widget.Button').all()
        btns[-1].click() # click on the last button (skip ad button)

if __name__ == "__main__":
    while True:
        like_user()
