ADB DPI Change

Introduction

ADB DPI change is a command-line tool that allows developers to change the display density of an Android emulator or device using the Android Debug Bridge (ADB). This can be useful for testing an app's compatibility with different screen densities or for simulating a particular device's screen size.

Usage

The syntax for using ADB DPI change is as follows:

adb shell wm density <dpi_value>

The <dpi_value> parameter should be replaced with the desired DPI value, e.g. 320 for an xhdpi screen.

By default, the DPI value is set to 160, which is equivalent to mdpi density.

Note: Changing the DPI value may affect the layout and scaling of the app's UI, so be sure to thoroughly test your app after using this tool.

Examples

To change the DPI value to 320, enter the following command:

adb shell wm density 320

To see the current DPI value, enter the following command:

adb shell wm density

Conclusion

ADB DPI change can be a useful tool for developers who need to test their app's compatibility with different screen densities or simulate a particular device's screen size. By changing the DPI value using ADB, developers can accurately test their app's UI on different configurations.
