How to run your UIAutomator in your own device?

The first thing we need to know is that inside Android, we need to convert jar files into the dex format, since Dalvik virtual machine is used. We could use dx.bat to convert this uiautomator.jar into uiautomator.dex. A dx.bat of certain version of Android should be located in the build-tools folder of Android SDK. You could run this command in your shell.

/Path_To/Android/Sdk/build-tools/30.0.2/dx.bat --dex --output="/Path_To/uiautomator.dex" "/Path_To/uiautomator/out/artifacts/uiautomator_jar/uiautomator.jar"

Then you need to push this dex file inside your target device. Like this:

adb push /Path_To/uiautomator.dex /data/local/tmp

Then you could run this modified uiautomator with:

adb shell CLASSPATH=/data/local/tmp/uiautomator.dex app_process /system/bin com.android.commands.uiautomator.Launcher dump

Then you could find the corresponding UI hierarchy file in your target device.
