QUESTION
Filtering property of type array on an array of objects by using another array
Asked 2022-Mar-21 at 22:11I have an array of objects that needs to be filtered by using two menus. Each menu returns an array. The values of these arrays will be used to filter the object array.
I have created a codepen example here : https://codepen.io/jonathank2018/pen/LYeZgQG?editors=1010
For this example lets concentrate on the "Aces" menu only. The filtering logic that i am trying to make is the following. scenario 1 : When I select "Services" from the "Aces" menu, the value of "valuesAces" becomes ["Services"]. scenario 2 : When I select "Services" and "Connected" from the "Aces" menu, the value of "valuesAces" becomes ["Services","Connected"]. When I filter "linksArray" with the values returned from "valuesAces", I need the result to be an array with all the objects that have within their aces property at least one of the items in "valuesAces".
for scenario 1 , I expect as result all the objects that have as their aces property ["Services"] as unique value, and ["Services", "othervalues...","othervalues..."].
1scenario1 = [ // services selected
2 { "src": "WayRay", "target": "AGP", "aces": [ "Services" ], "topic": [ "Map_Localisation" ] },

21If the object's aces property has at least one or several values from valuesAces, then it needs to be in the result of the filter.
The problem I am currently facing with my codepen example, is that it is not filtering the way I want it to. Right now if i refer to scenario 2, in the result I only find the objects that have as aces property either "Services" or "Connected" as first item of the array , but not the objects that have several items in the aces property and where "Services" or "Connected" are not at index 0. It seems to ignore all other items in the array exept for the first one.
My filtering function looks like this :
1scenario1 = [ // services selected

41ANSWER
Answered 2022-Mar-21 at 22:11You could filter the linksArray array based on checking if linksArray.aces array items exist in valuesAces as follows:

OAuth2 Redirect URI not valid
Asked 2022-Mar-06 at 22:42I'm trying to authenticate to OpenStreetMap via OAuth2 using AppAuth. Via Custom Tab I can retrieve the authorization code but the redirect URI does not open my app but gives an Address Not Found error in the Custom Tab. As you can see as I was experimenting around to solve this issue I used app.example.com as host name, although the package name is com.example.app, but even if I do use the package name as host name in the redirect URI (and change this in the manifest, gradle, osm etc.), it still does not work but results in an Invalid Redirect URI error. So I would assume something with the redirect URI isn't quite right, but I cannot figure out what it is.
Also I cannot use a custom scheme, as OSM only accepts https redirect URIs.
MainActivity.java:

51In OSM I have set the redirect URI to https://app.example.com/oauth2redirect
Weirdly enough it worked once yesterday, but does not anymore since today. I reverted any changes, reset the app, deleted any data and restarted my phone, but couldn't make it work again.
I've tried to show as little code as needed, please let me know if you need further information for solving this problem.
Edit: I just noticed that it works on Pixel 5 API 30 virtual device, but not on my real device (Xiaomi Poco X3 Pro API 30) nor on Nexus 6 API 30 virtual device. I'm quite confused

54There is a known issue where OAuth HTTPS responses don't automatically return to the app from a Chrome Custom Tab, unless there is a User Gesture first, such as a button click. If possible, show an OAuth consent screen as an initial solution to this.
If you want something to compare against try running my demo app and see if this gives you some ideas. Note that recently I've seen problems on emulators that use APIs 31 and above, though no problems on my Google Pixel phone, which runs Android 12.

How to make completely transparent status bar?
Asked 2022-Jan-29 at 10:02I want to make so my status bar is transparent, but also without icons on it. I managed to make it so that bar disappeared, but then it left a line that isn't filled with the background. I want to change that so i can actually see the background without any icons being in the way.
Also, I'm testing it on Xiaomi Redmi Note 8T

ANSWER
Answered 2021-Oct-25 at 16:41This is the known bug in the microsoft-authentication-library-for-android.
You can authenticate by edit the auth_config.json file in the Raw folder and change the user agent to this authorized_user_agent : WEBVIEW.
You can authenticate the user using the Webview instead of the browser and from this way your app will not be crashed.
Look into this pull-request.
QUESTION
Why doesn't the data from the server come to the app on the real device?
Asked 2021-Nov-04 at 15:00When the application starts, a request is sent to the server (which is located locally on my computer) to get a list of posts. In theory, the server should process the request and return this list of posts. But it doesn't return anything. In LogCat there are no errors, but when debugging, an exception is thrown instead of a server response:
1((SocketTimeoutException)e).detailMessage = failed to connect to /192.168.1.35 (port 9999) from /192.168.1.33 (port 49742) after 30000ms
2When I try to add new post (post to server via Post method) I get error at LogCat. Here is the text of the error:

35IP-address and port are correct. On native android-studio emulator I enter address 10.0.2.2:9999 - posts are coming. I use Genymotion emulator (which has its own IP) and enter 192.168.1.35:9999 - the answer from the server comes too. Only the real devices (Xiaomi Redmi 5 and Nexus 5X) do not respond. Help to solve the problem, please!
UPD: Thanks everybody for your help, guys! I've tried everything, but the problem was really caused by the turned on firewall)
ANSWER
Answered 2021-Nov-03 at 17:38The firewall on the server pc can block incoming connections. Switch it off to test.
The server can be bound to localhost only. Dont bind your server and if you have to bind it to 0.0.0.0.
QUESTION
New instance of a class contains older data given to an older instance
Asked 2021-Oct-08 at 11:06I'm trying to analyze some reviews using vader in python. I made an Analyzer class like so:
1class Analyzer:
2 dataframe = None
3 reviews = []
4
5 # other data
6
7 def __init__(self, brand):
8 self.dataframe = pd.read_csv(brand) # using pandas
9 reviews = self.dataframe['Reviews'].tolist()
10
11 def analyze(self):
12 # code for analyze...
13
14 # more codes...
15and I used this class in main.py like so:
1class Analyzer:
2 dataframe = None
3 reviews = []
4
5 # other data
6
7 def __init__(self, brand):
8 self.dataframe = pd.read_csv(brand) # using pandas
9 reviews = self.dataframe['Reviews'].tolist()
10
11 def analyze(self):
12 # code for analyze...
13
14 # more codes...
15from analyzer import Analyzer
16
17brands = [
18 'apple',
19 'google',
20 'huawei',
21 'motorola',
22 'nokia',
23 'samsung',
24 'sony',
25 'xiaomi'
26]
27
28for brand in brands:
29 analysis = Analyzer(brand)
30 analysis.analyze()
31 del analysis
32now the problem is: When brands are given to the class to be analyzed, the older reviews remain in the list.
e.g.:
apple.csv has 1000 reviews and google.csv has 700 reviews. but when google is passed to analyzer, the reviews list length is not 700, but 1700.
ANSWER
Answered 2021-Oct-08 at 08:56reviews attribute is for class and not object, since you defined it in the body of the class.
define the reviews in the body of __init__:
1class Analyzer:
2 dataframe = None
3 reviews = []
4
5 # other data
6
7 def __init__(self, brand):
8 self.dataframe = pd.read_csv(brand) # using pandas
9 reviews = self.dataframe['Reviews'].tolist()
10

55 : declaringClass.getDeclaredMethod(name, parametersArray);
56 } catch (NoSuchMethodException e) {
57 throw new IncompatibleClassChangeError("Couldn't find " + declaringClass.getName()
58 + "." + name + Arrays.toString(parametersArray));
59 }
60Then look to Class::getDeclaredMethod documentation.
Returns a Method object that reflects the specified declared method of the class or interface represented by this Class object. ... If the name is "<init>"or "<clinit>" a NoSuchMethodException is raised.
Kotlin global property and companion object property initialization compiles to Java static initialization block aka <clinit>.
Puzzle complete. Move LifecycleObserver declaration from static property somewhere else and problem will be solved.
Why Android 5 and 6 only? I think it's just getDeclaredMethod implementation differences. We see crashes on Android 5 and 6 only too.
QUESTION
Will i get the entire document from the firestore?
Asked 2021-Sep-20 at 13:41
hi. i have a database as in the picture above i have a smartphones collection with many documents(i.e. iphone or xiaomi) inside. i will use react to render this information and i want to load it from part to part. i.e. i want to render all of the smartphones on the main page and filter them... so for the main page i will only need description and ratings and for the full product details i will need tech specs and reviews. imagine that the whole document weight is 1mb 100kb both descriptions 200kb for tech specs 400kb reviews and 200kb ratings my question is:
- if i want to load only ratings and short description for the main page of 100 products. can i get only 300kb data from each product or i will get the whole 100mb data ???
- if i want to edit only camera 64mpx .. can i do this without getting all the document from the DB?
- is there any easy tool to add/edit/remove data in the firestore DB like MongoDBCompass ?
- any information about how read/add/edit operations works in firestore?

You can load only ratings as it's a document on it's own document. You cannot load only short description as you cannot fetch a single field from a document. You'll get both short description and full description fields. (Do note that this won't include documents from the sub-collections i.e. reviews, tech specs in this case)
if i want to edit only camera 64mpx .. can i do this without getting all the document from the DB?
As long as you know ID of that document (smartphone document), you can using following update operation:
1const phoneRef = firebase.firestore().collection("smartphones").doc("smart_phone_id")
2
3const mediaRef = phoneRef.collection("tech_specs").doc("media")
4mediaRef.update({ camera: "108px" })
5is there any easy tool to add/edit/remove data in the firestore DB like MongoDBCompass ?
Firebase's console (where the screenshot is from) is one but there isn't any one click import built natively.
