Determining the screen size and density of an Android device can be crucial for developers, especially when optimizing applications for various devices. This guide provides a method to retrieve this information using Android Debug Bridge (ADB) commands, ensuring you have the necessary details to enhance your application’s compatibility and performance.
Retrieving Screen Size and Density
Android provides several ways to access device screen information through ADB. Below is a straightforward approach using the WindowManager service:
Using WindowManager Commands
To get the screen resolution and density, you can use the following ADB commands:
- Screen Resolution: Execute the command below to fetch the physical screen size.
adb shell wm sizeThe output will display the physical size, such as 2880×1600.
adb shell wm densityThis command will return the physical density, for example, 320.
In addition to retrieving the current values, you can also override the density by specifying a new value:
adb shell wm density 160Alternative Methods
For developers seeking additional details or alternative methods, the following commands can also be useful:
- Using Dumpsys: Provides comprehensive display information.
adb shell dumpsys window displays - Accessing LCD Density: Extracts density from the
build.propfile.adb shell getprop ro.sf.lcd_density
Enhancing Your Testing Process
Accurate screen size and density information are vital for testing applications across various devices. If you’re looking for a streamlined way to automate this process, consider using a no-code test automation tool like Repeato.
Repeato allows you to create, run, and maintain automated tests for iOS and Android apps with ease. Its integration with ADB enables you to execute commands, including screen size and density queries, efficiently as part of your test scripts. By leveraging computer vision and AI, Repeato ensures fast editing and execution of tests, enhancing your development workflow.
