Processing list in Coroutines scope causes exception

Asked 2022-Feb-19 at 19:05

I have a function that show markers (I call it tasks) on Google Maps. To make it cleaner, I chose an approach that iterates through the already displayed tasks and the new tasks. If a task already exists in maps and does not in the new list, I delete its marker. If the task is in both lists but its version has changed, I modify its marker . And if the task is only in the new list, i add its marker. Each time the user scrolls through the maps, I search for tasks based on the scrolled positon. The user can scroll multiple times, which should stop the previous call of the function.

the problem is that sometimes i get this exception

I assume the java.util.ConcurrentModificationException exception occurs for alreadyDisplayedMissions list. You can try to use a Job instance, returned by launch function. You can cancel the current job when the next one is started. In this case you should check whether the current job is active by using isActive property or ensureActive function:

private var job: Job? = null

I don't know if you are reading this, but you have forgotten to include ON_START event for lifecycle, so you are throwing the exception. Also you are calling onStart on ON_CREATE.

Also consider populating the lifecycleObserver to be scoped into the DisposableEffect and make the DisposableEffect also aware of the mapView (give it as an argument).

Google Maps SDK for Android: Smoothly animating the camera to a new location, rendering all the tiles along the way

Asked 2021-Oct-07 at 14:02

Background

Many similar questions seem to have been asked on SO before (most notably android google maps not loading the map when using GoogleMap.AnimateCamera() and How can I smoothly pan a GoogleMap in Android?), but none of the answers or comments posted throughout those threads have given me a firm idea of how to do this.

I initially thought that it would be as simple as just calling animateCamera(CameraUpdateFactory.newLatLng(), duration, callback) but like the OP of the first link above, all I get is a gray or very blurry map until the animation completes, even if I slow it down to tens of seconds long!

I've managed to find and implement this helper class that does a nice job of allowing the tiles to render along the way, but even with a delay of 0, there is a noticeable lag between each animation.

Code

OK, time for some code. Here's the (slightly-modified) helper class:

Here's my attempt using your utility frame player.

A few notes:

The zoom value is interpolated based on the total steps (set at 500 here) and given the start and stop values.
A Google Maps utility is used to compute the next lat lng based on a fractional distance: SphericalUtil.interpolate.
The fractional distance should not be a linear function to reduce the introduction of new tiles. In other words, at higher zooms (closer in) the camera moves in shorter distances and the amount of camera movement increases exponentially (center-to-center) while zooming out. This requires a bit more explanation...
As you can see the traversal is split into two - reversing the exponential function of the distance movement.
The "max" zoom (bad name) which is the furthest out can be a function of the total distance - computed to encompass the whole path at the midpoint. For now it's hard coded to 4 for this case.
Note the maps animate function cannot be used as it introduces its own bouncing ball effect on each step which is undesirable. So given a fair number of steps the move function can be used.
This method attempts to minimize tile loading per step but ultimately the TileLoader is the limiting factor for viewing which cannot monitored (easily).

Flutter Google Maps - Move camera to current position

Asked 2021-Aug-05 at 15:00

In my Flutter project I use the Google Maps plugin to display a map in the app. On the map I want to show the current location of the user and for this I use Geolocator.

When the map loads it will load on a static point and when the user denies the location permissions the user can still use the map without location. When the user accepts the permissions I want to move the camera to the users current location.

I have implement above in the code below but I also get the following error and I can't figure out how to solve it.

After the filtering, you have a Stream>. Collecting with toSet() (which accepts no arguments) would collect Entrys, but you want to map each element to their key prior to collecting instead.

You must first map the elements of the resulting stream to the Entry's key:

You have two options that work with pessimistic locking:

There is a third option: use optimistic locking instead, and retry the transaction if another transaction modifies the key. But this would not work with @TransactionalAttribute, you would have to call TransactionManager.commit() yourself and catch the WriteSkewException.

It is because you have incorrectly calling a function. You're using await canLaunch(googleUrl); instead of await launch(googleUrl); in the if part.
