I'll try to import Folium pakage, but I'have an error.
In build.gradle I have added install folium :
`android {
compileSdkVersion 26
defaultConfig {
applicationId "com.chaquo.python.hello"
minSdkVersion 16
targetSdkVersion 22
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
python {
// If Chaquopy fails to find Python on your build machine, enable the following
// line and edit it to point to a Python 3.4+ executable.
//buildPython "C:/Python37/python.exe"

        staticProxy "hello"
        extractPackages "Data"

        pip {
            // install "setuptools"
            install "folium"
        }`

I have an error when import folium is execute.
I have tried to add setuptools but I have an exception with pkg_ressouces.
If you have a solution ?

If I take the Hello World project and I add :
pip { install "folium" }
inside build.gradle of App,
If I put in Hello.py :
from folium import Map
compilation is ok but the application crash when start
Sorry, I don't know how to catch the error.

You can probably find it in the Logcat window in Android Studio. Or if that fails, just take a screenshot.

OK, you were right to add setuptools, and here's the log after you do that:

We'll fix this properly in the next version of Chaquopy. Meanwhile, try working around it by adding these lines before you import folium:

import pkg_resources
pkg_resources.NullProvider._has = lambda self, path: True

I have another problem with folium.
Import function is ok, but when execute the main folium function I have an error :

coords = [48.8398094,2.5840685]
map = Map(location=coords, zoom_start=15)

can't perform this operation for unregistered loader type

I have submit this error to folium team, but they answer it's not a folium error.

OK, this will have to wait for the proper fix. We plan to release it within the next couple of weeks. Sorry for the inconvenience.
