AudioRecorder in android using python

i have a problem:
This is the run function after I click on the kivy button
And I know that time.sleep is used badly here, but how can I possibly
replace it?
from jnius import autoclass
def run(self):
self.r = MyRecorder()
self.r.mRecorder.prepare()
self.r.mRecorder.start()
self.console.text += "Recording.."
time.sleep(1)
self.r.mRecorder.stop()
self.r.mRecorder.release()
self.console.text += "Recording stopped.."
This is the recorder class (Is everything right?)
class MyRecorder:
def __init__(self):
'''Recorder object To access Android Hardware'''
self.MediaRecorder = autoclass('android.media.MediaRecorder')
self.AudioSource = autoclass('android.media.MediaRecorder$AudioSource')
self.OutputFormat = autoclass('android.media.MediaRecorder$OutputFormat')
self.AudioEncoder = autoclass('android.media.MediaRecorder$AudioEncoder')
# create out recorder
self.mRecorder = self.MediaRecorder()
self.mRecorder.setAudioSource(self.AudioSource.MIC)
self.mRecorder.setOutputFormat(self.OutputFormat.THREE_GPP)
self.mRecorder.setAudioEncoder(self.AudioEncoder.AMR_NB)
self.mRecorder.setOutputFile('./MYAUDIO.3gp')
Here's the error I got:

Can anyone help me please? Thanks!

I don't have a lot of experience in Kivy, but based on my experience developing some native android Apps, looks like you didn't ask for record audio permission on your code.
Based on this video (start on 27:48), you need to request access putting on your code something like:
from android.permissions import Permission, request_permissions
def callback_func(permission, results):
if all([res for res in results):
print("All permissions granted")
else:
print("Did not get all permissions")
request_permissions([Permission.RECORD_AUDIO], callback_func)
Remember to ask for the record permission BEFORE using the microphone.
You can read all the permissions here.

Error with on reaction add, How to resolve this?

Code Example
#client.event
async def on_reaction_add(reaction, user):
channel = reaction.message.channel
if reaction.emoji == '🇪🇸':
translaty = translator.translate(
str(reaction.message.content), lang_tgt='es')
await channel.send("Translating {}'s message: {}".format(str(reaction.message.author)[:-5], reaction.message.content))
await channel.send("`" + str(translaty) + "`")
The current code was working however i am not getting the following error.
Ignoring exception in on_reaction_add

Any help would be greatly appreciated, my mind has just gone blank and cannot seem to work it out. As I stated above this worked about 1 week ago and i have not touched the code since, but now I just get the above error.

I think you're suffering from an unfortunate error with the google translate library you're using to translate the message.
Had a quick look online and someone's already posted a workaround here

Celery + Azure Service Bus (Broker) = claim is empty or token is invalid

I am trying to use Azure Service Bus as the broker for my celery app.
I have patched the solution by referring to various sources.
The goal is to use Azure Service Bus as the broker and PostgresSQL as the backend.
I created an Azure Service Bus and copied the credentials for the RootManageSharedAccessKey to the celery app.
Following is the task.py
from time import sleep
from celery import Celery
from kombu.utils.url import safequote
SAS_policy = safequote("RootManageSharedAccessKey") #SAS Policy
SAS_key = safequote("1234222zUY28tRUtp+A2YoHmDYcABCD") #Primary key from the previous SS
namespace = safequote("bluenode-dev")
app = Celery('tasks', backend='db+postgresql://afsan.gujarati:admin#localhost/local_dev',
broker=f'azureservicebus://{SAS_policy}:{SAS_key}=#{namespace}')
#app.task
def divide(x, y):
sleep(30)
return x/y
When I try to run the Celery app using the following command:
celery -A tasks worker --loglevel=INFO
I get the following error
[2020-10-09 14:00:32,035: CRITICAL/MainProcess] Unrecoverable error: AzureHttpError('Unauthorized\n<Error><Code>401</Code><Detail>claim is empty or token is invalid.

I don't see a straight solution for this anywhere. What am I missing?
P.S. I did not create the Queue in Azure Service Bus. I am assuming that celery would create the Queue by itself when the celery app is executed.
P.S.S. I also tried to use the exact same credentials in Python's Service Bus Client and it seemed to work. It feels like a Celery issue, but I am not able to figure out exactly what.

If you want to use Azure Service Bus Transport to connect Azure service bus, the URL should be azureservicebus://{SAS policy name}:{SAS key}#{Service Bus Namespace}.
For example
Get Shared access policies RootManageSharedAccessKey
Code
from celery import Celery
from kombu.utils.url import safequote
SAS_policy = "RootManageSharedAccessKey" # SAS Policy
# Primary key from the previous SS
SAS_key = safequote("X/*****qyY=")
namespace = "bowman1012"
app = Celery('tasks', backend='db+postgresql://<>#localhost/<>',
broker=f'azureservicebus://{SAS_policy}:{SAS_key}#{namespace}')
#app.task
def add(x, y):
return x + y

Django Closed Socket Error with Repeated AJAX Calls [WinError 10053] An established connection was aborted by the software in your host machine

I'm trying to implement a live search through the jquery plugin Select2 in my Django 1.11.4 project. Running Python 3.6. When I type in the textbox, the server doesn't seem to be able to handle the number of requests and it closes, followed by these series of errors.
I've spent a couple hours following a couple threads on SO SO(more) , Google, etc but none have a working solution. I thought it was a python version issue, but I've upgraded from 2.7 to 3.6 and still have it. Any help would be great thanks!
This the view that's being called by the ajax call:
def directory_search(request):
# Query text from search bar
query = request.GET.get('q', None)
if query:
# Searches the DB for matching value
customers = Customer.objects.filter(
Q(name__icontains= query)|
Q(contract_account__icontains= query)|
Q(address__icontains= query)|
Q(address__icontains= query)|
Q(email__icontains= query)
).distinct()
# Turns queryset into dict
customers = customers.values("contract_account","name")
# Turns dict into list
customers_list = list(customers)
return JsonResponse(customers_list, safe=False)
else:
return JsonResponse(data={'success': False,'errors': 'No mathing items found'})
This is the js/ajax call for the Select2 plugin:
$(".customer-search-bar").select2({
ajax:{
dataType: 'json',
type: 'GET',
url:"{% url 'portal:directory_search' %}",
data: function (params) {
var queryParameters = {
q: params.term
}
return queryParameters;
},
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
id: item.contract_account
}
})
};
}
},
escapeMarkup: function (markup) { return markup; },
minimumInputLength: 1,
templateResult: formatRepo,
templateSelection: formatRepoSelection,
language: { errorLoading:function(){ return "Searching..." }}
});

It seems to be a error on chrome. It didn't come to me, 'cause I was using Opera, but opera uses chromium as well. In internet explorer the error didn't show.
