Cannot build app: Missing device_filter.xml resource

[ham-a7]

It seems that this package does not work when following the readme build instructions. I noticed it said "these instructions are out of date and need updating" so I thought I would raise an issue. I am new to building apps with Buildozer so sorry if the package is working and I am just getting something wrong.

I cannot build the usbserial4a_ui_example.py example app into an APK file.

I follow the readme: I update the buildozer.spec file and add the intent-filter.xml file to the project folder. The build then fails as expected giving the error that is cannot find the device_filter.xml file (which I haven't added yet).

I then create an xml folder in the specified directory and add the the device_filter.xml to it.

However when I build the app it gives the same error; it cannot find the device_filter.xml file.

The error is:

Android resource linking failed
ERROR: /home/ham/Projects/usbserial/.buildozer/android/platform/build-arm64-v8a_armeabi-v7a/dists/myapp/build/intermediates/packaged_manifests/debug/AndroidManifest.xml:65: AAPT: error: resource xml/device_filter (aka org.test.myapp:xml/device_filter) not found.

Deviations I made from the instructions:

• Buildozer said that p4a_whitelist is deprecated so I changed it to whitelist in the spec file.

• The readme specifies this directory .buildozer/android/platform/build/dists/YOU_PROJECT_NAME/src/main/res however I have the folder build-arm64-v8a_armeabi-v7a in place of build.

Here is my AndroidManifest.tmpl.xml file so you can see where I have added the <uses-feature android:name="android.hardware.usb.host" /> line:
