backgrounded | simple background execution of model methods

I have a SpriteKit project in which I'm suddenly seeing the following error repeatedly printed to the logs when testing on a real device:

Execution of the command buffer was aborted due to an error during execution. Insufficient Permission (to submit GPU work from background)

This happens when the app is in the background state.

Now, it's pretty obvious what's going on: SpriteKit uses Metal, and the latter is committing new work to the GPU when the app is backgrounded (which is something you can't do).

I've confirmed this theory by not loading my SpriteKit scenes. If I don't load the scenes, the problem does not occur.

What I've tried:

In my SceneDelegate's sceneWillResignActive(_:) function, I tried setting isPaused to true, like this:

I'm currently trying to create a Flutter application that can vibrate users at a specific (not known) time caused by another user. My solution for the Android version was to enable push notifications using Firebase Cloud Messaging while also unoptimizing the battery (for the application). I heard the push notification when it's a high-priority payload will handle the App Doze (idle standby) and it works just fine on the android. I recently got push notifications working on the iOS version, but the notification doesn't seem to awaken the device (and allow it to listen for a change on Firebase Firestore so it can vibrate). One solution to this would be to run code (vibration API) if a push notification is received, but I'm not sure how to do this. Is there a way to make the application wake up from the suspended app state so it can check for changes on Firestore? Currently, it works when the app is backgrounded but that's not enough.

If it helps, here's my notification payload:

I am trying to create an anim file. But the lines in set tag has dark bacgrounden and when I move my mouse over that dark backgrounded place it says following message.

Unexpected text found in layout file: "android:interpolator="@android:anim/bounce_interpolator""

My app allows APNS notifications to come in whether the app is backgrounded or foregrounded, e.g.:

I'm currently making a chatroom-like app that works with firestore to connect users to a host's session. I ran into a problem where client devices lose connection / stop listening for firestore changes when locked/backgrounded for too long (to my knowledge it's because the device tries to save power by killing long-living processes). I learned that a workaround would be to send a FCM push notification to devices prior to changing the firestore doc so it'd reawaken the app and have the app listen for the firestore doc change. I'm not sure how to implement push notifications, but I learned that it requires a user specific token (that must be protected). Ignoring the fact that I'm not sure how to implement push notifications (noob-friendly pointers would be appreciated), would uploading the user token to firestore as a field be a viable approach? I'm thinking that I can use my helper function (which gets all non-hosts of a specific session) to also send push notifications to each person.

I have been working on a game and, for certain things, I used absolute positioning. In particular, I need it for some moving animations where I have to slide elements around and overlap them to create an effect.

I'm trying to work on making the game good-looking on mobile, and I've been running into some problems caused by Bootstrap columns that contain those absolutely positioned elements.

This is the look I'm trying to get (aside from the badly aligned number), notice the red squared row in the middle:

The whole center part of the screen (the row with buttons, emojis, and the centered card icon underneath) is a row containing cols. This is some of its markup

I have and app with gems image_processing and ruby-vips.

I need to create white backgrounded image 1920x1920, add some black text there and write it to tempfile.

How can I do this with code?

I have been working on a react native application where I have to fetch the geolocation at an interval of 10secs and update it to a server. I was able to do the same when the emulator was active/ in the foreground.

However, when the app is minimized, it doesn't work. I tried using expo task manager but the function doesn't seem to run when backgrounded.

What is the error here? I have attached my code and output.

I am using android 11 using an emulator and personal device.

Here is my code:

I have a simple design app where i have just a round image on the top right corner. I am trying to do something like what they have on the bloom app.

See how the edge of the image is getting cut off at the edge of the cell, I am trying to go for something like that, but I keep getting this.

I had a feeling that the entire cell is just an image so that it how it looks like that, but I don't know if making an entire cell image is what i want to do, since I plan to eventually be able to change the cell's color and the circle image's color at different times, and use different color, so it is not in my interest to use just a large image for the cell, since I might want to use different images too. It also seems to be easier to figure this out, than just create a couple dozen different images, which also increases it's app size.

I have looked at a few different posts, but none of them seems to work for me.

I tried:

• setting the frame of the image and background to the bounds
• using all the different content mode
• using clipsToBound, and masksToBounds and set them to either true and false.

this is what is in my cell:
