Android studio: thread app not returning same value as non thread app

Asked 2021-May-27 at 23:15

I'm working on an app that goes through all of the phone directories, and collecting all the songs. When i run it normally it works fine, just takes about 6 seconds to go through everything, and causes the app to skip a lot of frames. I changed it so every time a file is found, a different thread reads the metadata and saves it. I'm also waiting for all of them in the end, because after that I'm trying to use that list. All of a sudden several of the song are null, even though they're not initialized as such anywhere. What can cause that? an app that works fine, but not with threads..?

You're dynamically trying to add new Threads to the list of threads on other threads, but reading that thread on one thread. That means you'll finish the loop on some subset of those threads before all of them are added. This entire approach is one big race condition.

This isn't something threads are going to speed up much, and you're doing your threading all wrong anyway. Throw this out and just do it on a single background thread, and do not join on that thread (or you may as well do it sequentially)- have it post back to the main thread when done.

I'm uploading images to a Trello Card using the Trello API. Trello by default set the image as the cover image. The API documentation says there is a setCover option but I cannot get it work.

setCover should be in params, not in files/values. You may also need to make it str(cover).lower() since it's expecting true/false and not True/False.

Load product image everywhere in the Shopware 6 storefront from external URL at runtime without saving it in filesystem

Asked 2020-Sep-07 at 05:19

I am changing the image of a product from an external URL at runtime on saleschannel.product.load event. This all works fine, but when placing the order, it gives the error about

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`sv3_dev`.`order_line_item`, CONSTRAINT `fk.order_line_item.cover_id` FOREIGN KEY (`cover_id`) REFERENCES `media` (`id`) ON UPDATE CASCADE)

I am guessing it is because I am overrwriting the media entity of the product with my custom implementation like this, so it does not find the media cover ID when inserting the order line item:

ANSWER

Answered 2020-Sep-07 at 05:19

To anyone else who stumbles upon this, dynamically adding the media entity like mentioned in the question works for the rest of the shop except when placing the order, as it requires a media ID due to FK constraint. So what I did was that I created a media entity from the mediaRepository and used that ID as reference for the order instead of the Uuid::randomHex() without saving the actual image in the filesystem.

QUESTION

Not receiving the data for Cover from IGDB

Asked 2020-Jul-16 at 13:26

I am struggling for some weeks with getting data from IGDB API using retrofit. I am trying to get the URL of the game cover and wanna display it in a GridLayout using fragments. But I am getting the "attempt to invoke virtual method on a null object reference". Can someone have a look at my code and see what I am missing? Thanks in advance!

ANSWER

Answered 2020-Jun-15 at 16:01

Your API call is correct. But few of the objects in the response array are not having all the required fields or objects.

For example: The below object from the response does not have genre and cover. { "id": 91579, "name": "Racing Live", "popularity": 1.0 }

In this case, Your code will throw NullPointerException.

To fix the issue, update the code of onBindViewHolder method in GameAdapter class.

Why can't the database still not save the data with my current TypeConverter?

Asked 2020-Jul-16 at 13:23

I am stuck with implementing a TypeConverter to my Database. I have added the TypeConverters but it still keeps saying that it cannot figure out how to save the field into the database. Or maybe I have missed something? I was following this article to create TypeConverters (https://android.jlelse.eu/room-persistence-library-typeconverters-and-database-migration-3a7d68837d6c), which is with my knowledge so far a bit hard to understand. Any help would be appreciated!

Your DB contains Lists of Genre, Platform, ReleaseDate and Video. SQLite supports column types of INTEGER, REAL, TEXT and BLOB. You must provide methods for conversion of your List types to/from String(TEXT) or one of the other supported SQLite types.

Not receiving all data from IGDB Api using retrofit

Asked 2020-Jun-17 at 07:08

I am building an app using the IGDB Api to get a list of games to display in the app. I am using the retrofit library as well. Currently I am trying to get the game cover being displayed in a GridView but for some reason I get null from the Api as result when I am calling for the cover URL and also other data except "id". Can anybody help me finding out why I am getting null? Thanks in advance!

EDIT: I think there might an issue getting data from IGDB. I realised when I set an empty string in Call> call = service.getAllGames(FIELDS); I get the same results, where I only get the ID. Can't figure out why though :/

ANSWER

Answered 2020-Jun-16 at 07:47

You are missing the fields body - parameter on the GetDataService.

The documentation (https://api-docs.igdb.com/?kotlin#game) states that you should always put in a field body, to filter the fields you want to display.

I'd recommend starting to get the REST requests correct first, by using Postman or curl: First use the tool to form the request so that the response fits your expectations, and only then start creating the actual app implementation.

So the steps would be: Request all the games using the /games endpoint specifying all the fields as a body to the POST request. Once you got the id for the covers, request /covers and filter for the covers you actually want to display, afaik.

Good luck.

How to collapse text in a header while keeping buttons right justified?

Asked 2019-Nov-26 at 03:34

I am struggling to find a way with css to lock some buttons on the right side of my header, while collapsing the text if it gets as wide as the buttons. I want to keep them justified and just text-overflow: ellipsis the main text of the breadcrumb trail but can't seem to figure it out.

Fiddle is here: https://jsfiddle.net/hLcm8jsf/
