intarray | Integer array extension for PHP with fast set operations

kandi X-RAY | intarray Summary
PHP arrays are overkill for storing primitive integer values. They are slow and consume huge amounts of memory. Did I mention that serialization of PHP arrays adds a lot of overhead?. Intarray (Integer array) PHP extension is a space and time efficient tool for handling large int32_t arrays and performing lookups and set operations. Basically each intarray is just a PHP binary string and Intarray extension provides a bunch of functions for performing operations on it.

QUESTION
My app widget (ListView showing game scores) works fine when created on the home screen, but when I call appWidgetManager.updateAppWidget(id, R.id.appwidget) inside the provider, there is no reaction from the widget or the log calls in the RemoteViewsFactory's onCreate() or onDataSetChanged() methods. I know that the updateAppWidget gets called because I can see the log call right before it.
Why is the widget not updating?
My AppWidgetProvider:

Answered 2021-Jun-11 at 18:02It seems the layout passed to the remoteViews is cached, and you have to use a different layout for it to work. I used two different layouts to update the widget based on a boolean, and it worked.

I am trying to make the connection between adapter and fragment, but I get the following error when I try to filter the data for SearchView: Function invocation 'filter(...)' expected. As now I am learning Android, any input will be helpful for me. Thank you!
...ANSWER
Answered 2021-Jun-07 at 16:49There is a few things wrong with this code. If you would try and follow these steps (can be done in in onCreateView).
Init the recyclerview that is associated with this layout. RecyclerView recyclerView = findViewById(R.id.recycler_view);
Init the adapter that you would like to link with this recyclerview. adapter = new MyAwesomeAdapter(myAwesomeCountryList);
Add the adapter to the recyclerview. recyclerView.setAdapter(adapter);
Adding a layoutmanager to the recyclerview. recyclerView.setLayoutManager(layoutManager)
If you have done that, you are quite close (hopefully it solves it but there are more things we can not see, such as how you set up your associated layout).

In Kotlin, the type system distinguishes between references that can hold null (nullable references) and those that cannot (non-null references). For example, a regular variable of type String cannot hold null:
QUESTION
Simple question.
I have an array of ints in Android (Kotlin). I need to convert it to an org.pytorch.IValue. I believe that such a conversion can be done, but I can't figure out how to do it. This is my array
val array = Array(34) { IntArray(1) }
How do I get this wrapped in an IValue?
ANSWER
Answered 2021-Jun-01 at 19:09I found the way to do this by way of the Tensor object. The Tensor class has a static method for creating tensor buffers, such as by Tensor.allocateIntBuffer(). The argument for that call accepts the number of elements that the buffer will contain. The .put() method on the buffer places items within the buffer. Once the buffer is populated, it can be converted to an IValue with IValue.from(sourceTensor).
QUESTION
I am trying to retrieve the location every 10 seconds. The problem is that the location sometimes is null, and sometimes gives back an old location. When I update the location in my emulator it is not updating live.
Code to get location:
...ANSWER
Answered 2021-Jun-01 at 15:08You cannot rely on lastLocation completely , lastLocation can be null
Also lastLocation will return the device last known location so it will not update as the device location updates until and unless some other app is requesting location (like google map)
lastLocation literally means that we are not requesting for new Location, instead we are using location which are requested by other apps, so the lastLocation can be null or old
https://developer.android.com/training/location/retrieve-current
So Instead of relying on lastLocation use requestLocationUpdates, using which you can set the time interval like after how much time you want to receive the new location, so you don't have to implement CountDownTimer
I think for your case requestLocationUpdates will be the best option
Read below docs for how to request Location updates

QUESTION
So i have this simple program, which creates an array of 16 numbers, shuffles them, and then counts the cycles in the array.
...ANSWER
Answered 2021-Feb-08 at 22:17Try it like this using a map. Note that since you are destroying your array each time you need to make a copy before you pass it to the method (or in the method if you prefer). Also, the List is backed up by the array. So when the List is shuffled, so is the array.
The map initializes to 1 for each value if it doesn't exist. Otherwise it adds 1 to the previous value, instituting a count.
