I am trying to upload a file from a moblie phone to Google Drive, inside my android app. Basically Chaquopy is a plugin that enables me to run python scripts inside an android application and I use it to take advantage from PyDrive library and upload the file I want. But before that, I am just trying to stablish a connection with Google Drive but it refuses to retrieve the code from authorized redirect URI http://localhost:8080/ (that is how I configured my web application`s credential on google cloud project). I've already tried to transfer a file from pc to google drive with this project (and method) and it worked fine.
I've also tried to break gauth.LocalWebserverAuth() in steps as suggested in PyDrive documentation but get no code at the end of authentication (can't connect to localhost).
I would like to use this method to upload the file, but other methods may be considered too.
my build.gradle (app level)
defaultConfig {
applicationId "com.example.epshape"
minSdk 24
targetSdk 33
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
ndk {
abiFilters "armeabi-v7a", "arm64-v8a", "x86", "x86_64"
}
python {
buildPython "C:/Users/Administrator/AppData/Local/Programs/Python/Python38/python.exe"
version "3.8"
pip {
install "pydrive"
}
}
}
my python script:
from pydrive.auth import GoogleAuth
import os
def upload_dataset():
GoogleAuth.DEFAULT_SETTINGS['client_config_file'] = os.environ['HOME']+'/client_secrets.json'
gauth = GoogleAuth()
gauth.LocalWebserverAuth()
python script call from java activity class:
public void onClickUploadDataset(View view) {
Python py = Python.getInstance();
PyObject module = py.getModule("upload_dataset");
module.callAttr("upload_dataset");
}
error:

Thanks in advance!
I'm using another solution. I upload the file through a service account plus a shared folder in google drive. This video helped. I still run the python script with Chaquopy.
