QUESTION
I have an array of objects each with a groupName
key/value and then an item
key with an array of objects as it's value.
I'm trying to use .reduce()
with a forEach to iterate over the main array and merge all of the item values into a new Object with a single groupName and an items array containing all the original item values.
Every time I run the function I only get back the first value and I'm trying to figure out what I'm doing wrong.
Current Function:

and array#concat
to merge items
in movie array.
QUESTION
So I am relatively new to programming, and I have been working on this task app, where I want to save the data such as task name and more, given by the user. I am trying to accomplish this using Room. Now, initially, when I tried to do it, the app would crash since I was doing everything on the main thread probably. So, after a little research, I came to AsyncTask, but that is outdated. Now finally I have come across the Executer. I created a class for it, but I am a little unsure as to how I can implement it in my app. This is what I did :

QUESTION
I'm new to android studio and i'm not sure what was going on with it. How can I solve this error?
In the logcat, it mentioned that I required a view for recycler_food_list which apparently I had already coded into the foodlistfragment.java.
Logcat
...ANSWER
Answered 2021-Jun-15 at 03:29You're doing inflater.inflate(R.layout.fragment_menu, container, false);
, not inflating your R.layout.fragment_food_list
. You'll need to inflate the right layout to find your Recycler view.
QUESTION
I want to use navigation bottom menu with using navHostFragment in main activity. But when I run the program ,it stops on setContent in onCreat method MainActivity java code. I try to use bindig class insted setContent directly but nothing changes.
this is MainActivity.java
...ANSWER
Answered 2021-Jun-14 at 19:33It seems that your HomeFragment
doesn't have no parameters constructor.
If you want to use fragment that requires constructor parameters you need to provide FragmentFactory
to navigation component.
Add empty constructor HomeFragment()
to HomeFragment, and it should work.
QUESTION
I'm trying to implement an executorService to delete a huge Firebase node in background. This node gets a new record every ten seconds to feed a realtime linear graphic (259Krecords/month). The users need a function to clean the data from time to timen and they need to trigger it manually on demand.
I've coded the method below:
...ANSWER
Answered 2021-Jun-14 at 19:54I think I've found the problem. It happens that when I'm executing the "removeValue()" on firebase, it triggers it asynchronously. So, the for Loop is finished quite quickly giving me the LogCat above. I have added an OnSuccessListener to the remove command and am increasing the progress in there. Also, I've added a control variable in order to know when the processing is finished and thus close the progressbar. The end code, is like that:

Answered 2021-Jun-14 at 13:53As it was described in the reference:
When creating the NavHostFragment using FragmentContainerView or if manually adding the NavHostFragment to your activity via a FragmentTransaction, attempting to retrieve the NavController in onCreate() of an Activity via Navigation.findNavController(Activity, @IdRes int) will fail. You should retrieve the NavController directly from the NavHostFragment instead.
Looks like you should use
QUESTION
The app has:
- ListView listing player names from a DB table (only one column, so it is primary key)
- EditText to write the new name
- Button to update the name of player in the list
*there are more things, but i don´t want to make it more messy
I can click a name from the list and write a new name in the EditText. When you press the button that name is updated in the list.
Everything works correctly, but there is a problem. When I write a name that it is already in the list the app fails because primary keys cannot be repeated.
Is there some way to say "if EditText text already exists in the DB... then show a toast"
I already tried "if result of db.update is -1...then show a toast", but it doesn´t work.
This is the method in MainActivity:
...ANSWER

You have a UNIQUE index on the NUM_JUG column (perhaps implicit if NON_JUG is defined with PRIMARY KEY) and you are using the standard update method which uses the default conflict action of ABORT and therefore fails if an attempt is made to duplicate a NOM_JUG value.
As secondary issue is that the SQLiteDatabase update
method returns the number of updates (see extract and link below) (same for updateWithOnConflict
). The number returned will never be -1 it will be 0 or more (0 indicating that no updates have been applied).
As per SQLite Database - Update
Returns
int the number of rows affected
Fix
To fix the main issue you should use the updateWithOnConflict
method. This takes a 4th parameter a conflict and you probably want IGNORE so you could use :-

QUESTION
I have looked at all the SO posts related to this error, that I could find on Google. Most of them were about the requirement to add CHANNEL_ID in Android 8. Others were due to missing pieces of code, that I think are fixed in mine.
I have referred this article, and tried implementing the same. I am looking to send a Full Screen Intent notification.
Notifier.java
...ANSWER
Answered 2021-Jun-11 at 16:26I think, the problem is here. String.valueOf(R.string.channel_name)
just gives a string containing the integer ID. As a result, due to unknown/unregistered channel, you got bad notification error. Hence, use the actual String.
