I have made an app that retrieves data from a firebase real-time database and displays it in a RecyclerView.
MainActivity.java:
...ANSWER
Answered 2022-Feb-14 at 18:44Class com.example.myapplication.Dishes does not define a no-argument constructor.
so Dishes don't have no-argument constructor, thats correct as you have only one constructor in Dishes class

QUESTION
Hey guys I'm trying to save the following class to my collection on Firebase.
...ANSWER
Answered 2021-Dec-20 at 00:02I’m not sure if this is the root of your problem, but it may be.
LocalDateTime is not a timestamp
LocalDateTime is exactly the wrong data type for a timestamp. That class represents a date with time-of-day but lacks the context of a time zone or offset from UTC.
For a moment as seen in UTC, use Instant.
For a moment as seen in a time zone, use ZonedDateTime.
For a moment as seen with an offset from UTC, use OffsetDateTime.
To communicate a moment with a SQL-oriented database, use OffsetDateTime.
This has been covered many times on Stack Overflow, so search to learn more.

hi my android studio app keeps crashing when im sending data to firebase, the logcat gives me this error:

...ANSWER
Answered 2021-Nov-23 at 02:53It looks you're trying to send an EditText control to the database. Since Firebase only supports JSON types and an EditText is not a JSON type, you get an error message that says that.
You probably want to send the value that the user entered into the EditText to the database, so have a look at: Get Value of a Edit Text field
QUESTION
I am getting this error and I can't find the reason. I try to retrieve lat and long from Firebase. Here its my code from Java class:
...ANSWER
Answered 2021-Nov-21 at 10:18You are getting the following error:
FATAL ERROR com.google.firebase.database.DatabaseException: Failed to convert a value of type java.lang.String to long
Because you are trying to read the latitude and longitude as long values, while in the database are stored as strings, which is not correct. See the double quotes?
To solve this, you either change the type of the fields in the database to be numbers and you leave the code as it is, or you change the MapAdapter class like this:
QUESTION
I have a model data class with a few attributes. I have added some data into the Firestore and read them using this model class. Later, I decided to add a few more attributes in the model class but I have not added new fields in the Firestore database. When I read the data like before, my app crashes. This is obvious that as we go further we would add more details but we may or may not add these new details to old items that are already added to the database. How can I handle this situation?
This is how I am reading from the `Firestore'
...ANSWER
Answered 2021-Nov-15 at 22:24This isn't a problem with firebase fields. Try clearing your caches and restarting your computer. Please see this related question for more information:
java.lang.VerifyError: Verifier rejected class on Lollipop when using release APK
If you have a field in your model that isn't in the Firestore, it will be initialized to its default value. (in your case, "").
Additionally, if a field in the firestore does not exist in your model, it will be skipped during deserialization. A data class can only have a certain number of parameters, which probably is 245.

I tried making a RecyclerView that is getting data from Firebase Firestore and it's crashing.
It's not error with Adapter because when I add data manually to ArrayList it works just fine, I commented those lines.
I excluded Importing tags from code, everything is good there. I also double-checked name of collection on Firestore and in my code and it matches.
Here is my code:

Firstly I haven't made a empty constructor in Item class.
QUESTION
I'm trying to learn how to use Firebase, and decided to make a simple android application that uses the Firebase RealTime Database. The game requires a host who hosts a lobby, and players who can join that lobby. I made a host class that has a bunch of data types, among which is a list (the game involves using hints given to players by the host). I'm running into problems when I try to read from the database.
My lobby is a listview that I want to populate with a list of hosts in the database, but when I try to read from it I get this nasty error:
com.google.firebase.database.DatabaseException: Class java.util.List has generic type parameters, please use GenericTypeIndicator instead
I know that there are other questions about the same error, but I couldn't apply those answers with much success. I'm quite new to android development and would greatly appreciate any help.
Here is my user-defined class:

Answered 2021-Oct-25 at 00:20I've adapted the answer Frank and Alex mentioned in their comments. And it seems to be working in your situation. Instead of directly using

QUESTION
I have an images directory in Firebase Storage and I am trying to download all the files in that directory to my app. each image has a corresponding field in the database that stores its name the downloads are mostly successful but the app freezes and gets an App Not Responding prompt when you try to interact with ui or crashes after a while when you just wait.
below is the code i use to download the images to my app's storage directory '''
...ANSWER
Answered 2021-Oct-04 at 14:18You're downloading all files in parallel, which means that memory consumption is going to go up as the number of files goes up. To limit the memory consumption, download the files one by one, or with a reasonable maximum number of parallel downloads.
QUESTION
My android app was working fine until I make the following change. The change I made is, I added more editTexts to the Add Item activity and more texView to show them in the Item Details Activity. However, the app crashes on launch with the following error. The activities where I made the changes, Add Item and Item Details, are not called on launching the app. So I do not know why is my app crashing and what wrong I did. Can somebody help me find my mistake?
I am using Kotlin
ANSWER
Answered 2021-Sep-21 at 20:57So, the issue in my case was related to the excess number of EditText/TextView views. When I removed a few views, the error is gone and the app is working fine so far.
