+Ranger.vim uses a temporary file to store the path that was chosen, `/tmp/chosenfile` by default.
+This can be a problem if you do not have write permissions for the `/tmp` directory, for example on Android.
+There is a configuration variable for this called `g:ranger_choice_file`, this must be set to the
+path for a file that doesn't yet exist (this file is created when choosing a file and removed afterwards).
