QUESTION
I have a problem with changing the properties of a button in Kotlin. That is only in one function, it works fine in all others. It is weird because I can change the properties of a TextView in that function. Here is the function:
...ANSWER
Answered 2021-Oct-04 at 13:27I guess the issue here is that you are accessing the UI objects from a non UI thread and this is causing the issue. Accessing UI Element from a non UI Thread causes undefined behavior.
If you try to modify or even reference a UI object in a thread other than the main thread, the result can be exceptions, silent failures, crashes, and other undefined misbehavior.
You can read more about it here
To fix this problem you need to access the UI objects from a UI thread as below. Also its not good to do findViewById(R.id.someText)
inside the onResponse
as you are sure that the UI objects are always there. Instead initialize them inside the onCreate
and access the reference variable everywhere.

QUESTION
This is meant to be a countdown timer, the user enters the hours, minutes, and seconds. However, if I enter more than 0 hours, when the time should be 59:59 after it used to be 1:00:00, it goes to 1:-1:59. Can anybody tell me why this is?
...ANSWER
Answered 2021-Apr-14 at 19:54It makes for much simpler code to keep track of the total time in seconds, and then simply format it when you're printing it using modulo (%
) and integer division (//
).
QUESTION
I have a json response but I have some problems with using Gson or Klaxon because I only need one(or more if found) strings to put in an array. So i have an JSON, for example:
...ANSWER
Answered 2020-Nov-12 at 16:22The problem you have with Gson is that you are trying to cast the whole JSON to a part of the JSON. You have to either have a full class reflecting the complete JSON or traverse the JSON until you get where you need.

I need to parse very large JSON files that are downloaded from a server. These JSON files can contain completely different keys and values. Here are some examples...

Answered 2020-Oct-16 at 18:02If you are going to collect all items to a list anyways (instead of processing them immediately one by another), using streaming API makes not much sense. It can be done much simpler:

Crashlytics has been set up for my Android app for a while and working fine for normal Java/Kotlin code. I'm now trying to get Crashlytics to log NDK crashes using this guide: https://firebase.google.com/docs/crashlytics/ndk-reports.
I made the C++ crash and it does show up in Crashlytics as you can see in the screenshot below. But the stacktrace is missing a lot of info.
Top level Gradle file
...ANSWER
Answered 2020-Feb-20 at 00:10When contacting the Crashlytics helpdesk I got some steps to provide them with some logs. While going through these steps everything just worked, the stacktraces are showing up in Crashlytics as expected.
In case someone runs into any problems. Check the crashlytics logs (Thanks for the helpdesk for providing these steps!):
Linux / Windows: ~/.crashlytics/com.crashlytics.tools/crashlytics.log
Mac: ~/Library/Caches/com.crashlytics/com.crashlytics.tools/crashlytics.log
- Delete crashlytics.log file
- Run symbol upload gradle task
- Build and run app, run into test crash
Check crashlytics.log, it should contain something like this:
QUESTION
I am writing a simple Android app in Kotlin, which will show prayers divided into categories to user. There are 5 JSON files in assets folder, each of them has just around 10 KiB.
I use Klaxon for parsing the JSON files into those two data classes:
...ANSWER
Answered 2020-Jan-14 at 12:15Android assets seem to have bad reputation when it comes to performance. However, my testing proved that in this situation, it was Klaxon library who was responsible.
After finding major performance problem in Klaxon (see https://github.com/cbeust/klaxon/issues/154), which is still not fixed, I have tried recommended alternative: Moshi (https://github.com/square/moshi).
Moshi did improve performance, but parsing my JSON still took about 1 second.
After these experiments, I have resorted to the good old fashioned parsing using JSONObject:
