            Setting data to Firebase Causing My app to restart constantly with no Error in Logical
            Asked 2022-Mar-06 at 03:20

            I have been developing this app since 2019 and I had a released version of it and I was working on an update so there is a new version of the Android Studio came out I have updated Android Studio to Android Studio Bumblebee | 2021.1.1 Patch 1 my kotlin_version = "1.6.10" and compileSdk 31 minSdkVersion 19, targetSdkVersion 31 android 11

            I was solving some errors at the beginning like duplicate classes and stuff until I faced this error with firebase when setting the data to firebase Database or Firestore, before this update my Code was working fine and I didn't change much I just added new functions to the app like inAppReview,

            what is happening is that whenever I'm setting data or update some existing data in Firebase Databse or Firestore the app restart and leave no error to detect in the Logcat, Logcat will not be cleared it is just wont show error at the moment of restart, and my app will automatically set a new data to the Firestore or Firebase and some times restart when reading values,

            In the new update, I have come across errors like SQLiteConstraintException: UNIQUE constraint failed and E/android.vendin: Not starting debugger since process cannot load the jdwp agent. i dont know if it's related but those are showing.

            this is a serious problem guys, I have an iOS version same app written in Swift they both share the same functions to write and read to the database I mean same code different Languages connected to the same database there is no errors everything works fine on iOS with the firebase itself, and the same code was working before this update that's mean there's no problem with my code, please if anyone knows anything or came across this kind of situation let me know I need some help, I'm stuck for a week now I have been searching all over the internet Didn't found any answer, if anyone needs a further declaration or sharing some code please let me know

            emulator runing R version and the app was tested on a real Device SamsungNote S21

            Note: if I Run the app the first time and write to firebase the app will crash or as I mentioned restart.

            Note: but if I wrote to firebase and Re-run my app before the app write again or before the crash the app will works fone

            Answered 2022-Mar-06 at 03:20

            I see there are no problems with your dependencies and I think what you have is that you write data to the firebase database after getting some data using ValueEventListener, so even if your activity has destroyed ValueEventListener will still listen in the previous Activity according to this answer @ and this answer @ so it will restart and show no errors

            Android API 31 FLAG_IMMUTABLE Error using Firebase Auth UI
            Asked 2022-Jan-20 at 05:58

            I'm receving the below error in API 31 devices during Firebase Auth UI library(Only Phone number credential),



            Answered 2022-Jan-20 at 05:58

            In my case, firebase UI (com.firebaseui:firebase-ui-auth:8.0.0) was using which I found with the command './gradlew -q app:dependencyInsight --dependency play-services-auth --configuration debugCompileClasspath'

            This version of the play services auth was causing the issue for me.

            I added a separate

            implementation ''

            to my gradle and this issue disappeared.



            Parse many data from api to html with golang
            Asked 2021-Dec-18 at 21:18

            I am new in Go language so I have a question. I have API from where I need to parse information to cards. I have a script which GET all information from API and place it into fields in card. I understand how to take one part of information. But I need to create many cards with different information from API and place them on HTML page. How I can do this?

            server.go file for HTML hosting.



            Answered 2021-Dec-18 at 21:18

            There are a couple ways to handle templates. But you definitely want to parse your files once and store them.

            One way is to create a global var and store the template/templates in there.

            Also you expect a slice of Artist structs, correct? So you want to unmarshal into a slice, not a single object. If you check the error on unmarshal, you will see that.

            Last, there is a problem with the CreationDate field. Unmarshal error shows that too.



            Memory leaks when using static context items in android
            Asked 2021-Nov-21 at 21:56

            So I have a class with static UI elements like so:



            Answered 2021-Nov-21 at 21:56

            Static UI elements make no sense in Android First off, UI objects are bound to a specific Activity. They can't be used from other activities or displayed outside of their Activity. So making them static doesn't bring value

            Secondly, this will always be a memory leak. Each view has a reference to its Activity. Putting an Activity in a static variable means it can't be garbage collected, because there's a valid reference to it. That will basically cause every variable in that Activity to leak. Including the UI elements, which tend to be memory hungry (each image takes 4 bytes per pixel).

            You need to rethink what you're trying to do with this code. I actually can't tell. If you made them static so you can change them from other activities- don't do that. Make them based off a model object, and alter the data in the model instead. Let the UI reinitialize itself based off the model.

            Answered 2021-Aug-03 at 17:24

            This happens because you have 2 classes GroupieViewHolder in different packages. First of all check if you correct import the GroupieViewHolder.

            Generally your data classes and therefore your Items shouldn't be mutable, in that case, it'd look like so:



            Python numpy groupby multiple columns
            Asked 2020-Nov-01 at 20:04

            Is there a way to make a group by aggregation by multiple columns in numpy? Im trying to do it with this module: Goal is to get a faster groupby than pandas. for example:



            Answered 2020-Oct-30 at 10:08

            Given that group_idx has positive values, we can use a dimensionality-reduction based method. We are assuming the first three columns as the groupby ones and the last (fourth) one as the data column to be summed.

            Approach #1

            We will stick to NumPy tools and also bring in pandas.factorize in the mix.
