Stacktrace/Logcat

W: invalid resource directory name: /home/alex/apktool/Working/name/res navigation
then I use --use-aapt2 option (I found this solution here)
then I see this:

I found here recommendation to remove $ symbol and after this:
apktool b --use-aapt2 name -o v1.apk && java -jar signapk.jar testkey.x509.pem testkey.pk8 v1.apk v1-signed.apk && rm v1.apk

The resource avd_hide_password.xml is defined in support-design aar. It is a new kind of drawable animated-vector.

[iBotPeaches]

The fix for the filename is in v2.5.0 upcoming. The animated-vector is still a flat xml file, so should be handled without error.
