IOError: [Errno 2] No such file or directory: 'src/main/assets/private.mp3'

I'm on Ubuntu 16.04 (Linux). I'm getting this error at "getting started guide" from https://python-for-android.readthedocs.io/en/latest/quickstart/ with main.py containing hello world example from https://kivy.org/docs/guide/basic.html.
I installed Android Studio with Android SDK and NDK from https://developer.android.com/studio/index.html.
APK-Building was invoked in python virtualenv (because of pip install python-for-android) by following command.
p4a apk --private $HOME/src/kivy --package=org.example.myapp --name "My application" --version 0.1 --bootstrap=sdl2 --requirements=python2,kivy --sdk_dir $HOME/Android/Sdk --ndk_dir ~/Android/Sdk/ndk-bundle --ndk_version r16b

Any idea why building stopped at the following point:
(Thank you in advance...)

I detected the same problem, when I tried to update an existing (working) build from version 0.5.3 to version 0.6.0. It simply helped to add the missing directories to .... bootstraps/sdl2/build/main/... in the pythonforandroid installation. My init-script now looks like:

...
p4aversion='0.6.0'
ver=`python3 -m pip show python-for-android | grep Version`
echo "Version: $ver"
if [ "$ver" != "Version: $p4aversion" ]
then
  python3 -m  pip install --user "https://github.com/kivy/python-for-android/archive/${p4aversion}.zip"
  # this is a hack! 
  # These 2 directories, present in the downloaded tarball/zip, are lost during installation.
  # I add them again to make shure the build runs through.
  mkdir -p ~/.local/lib64/python3.5/site-packages/pythonforandroid/bootstraps/sdl2/build/src/main/assets
  mkdir -p ~/.local/lib64/python3.5/site-packages/pythonforandroid/bootstraps/sdl2/build/src/main/res/drawable
fi
...

There seems to be a problem somewhere in the setup of pythonforandroid. Also I suggest the build.py script should better check for directories - and fix them if necessary - before creating files.

Here is a patch that applies to the unpacked 0.6.0.zip:

$ unzip -q "0.6.0.zip"
$ patch -p 0 < "0.6.0.patch"
$ zip -rq "0.6.0.zip" "python-for-android-0.6.0"

@lufebe16 is this fixed then, should we not close the ticket?
