Why do Switch and ListView controls in MAUI not update with 2-way binding?

Asked 2022-Apr-11 at 09:33

This question is about two MAUI controls (Switch and ListView) - I'm asking about them both in the same question as I'm expecting the root cause of the problem to be the same for both controls. It's entirely possible that they're different problems that just share some common symptoms though. (CollectionView has similar issues, but other confounding factors that make it trickier to demonstrate.)

I'm using 2-way data binding in my MAUI app: changes to the data can either come directly from the user, or from a background polling task that checks whether the canonical data has been changed elsewhere. The problem I'm facing is that changes to the view model are not visually propagated to the Switch.IsToggled and ListView.SelectedItem properties, even though the controls do raise events showing that they've "noticed" the property changes. Other controls (e.g. Label and Checkbox) are visually updated, indicating that the view model notification is working fine and the UI itself is generally healthy.

Build environment: Visual Studio 2022 17.2.0 preview 2.1
App environment: Android, either emulator "Pixel 5 - API 30" or a real Pixel 6

The sample code is all below, but the fundamental question is whether this a bug somewhere in my code (do I need to "tell" the controls to update themselves for some reason?) or possibly a bug in MAUI (in which case I should presumably report it)?

Sample code

The sample code below can be added directly a "File new project" MAUI app (with a name of "MauiPlayground" to use the same namespaces), or it's all available from my demo code repo. Each example is independent of the other - you can try just one. (Then update App.cs to set MainPage to the right example.)

Both examples have a very simple situation: a control with two-way binding to a view-model, and a button that updates the view-model property (to simulate "the data has been modified elsewhere" in the real app). In both cases, the control remains unchanged visually.

Note that I've specified {Binding ..., Mode=TwoWay} in both cases, even though that's the default for those properties, just to be super-clear that that isn't the problem.

The ViewModelBase code is shared by both examples, and is simply a convenient way of raising INotifyPropertyChanged.PropertyChanged without any extra dependencies:

ViewModelBase.cs:

These both may be bugs with the currently released version of MAUI.

This bug was recently posted and there is already a fix for the Switch to address this issue.

QUESTION

Android Studio Emulator disappears after Bumblebee update

Asked 2022-Apr-05 at 09:47

So I recently updated my Android Studio to "Android Studio Bumblebee | 2021.1.1 Patch 1" and now I have this weird bug where my emulator would disappear randomly. It works fine for sometime but would randomly disappear. In the device manager it shows that emulator is running but in the emulator tab it shows "No emulator is currently running" As you can see from the screenshot attached green dot in the device manager that means "Emulator is running", whereas it isn't. The only way to get back emulator is to "cold reboot it" from the device manager. Anyone else facing the same bug? Any suggestions as to where to look trying to debug this. I've tried deleting and installing emulator again but the issue persisted.

Had exactly the same issue on BumbleBee and the only way that I found to go about this, was to use a detached emulator in a separate window.

To run the emulator in a separate window go to File > Settings > Tools > Emulator (On Mac -> *Android Studio > Preferences > Tools > Emulator ) and deselect Launch in a tool window.

This way the emulator will always be there.

QUESTION

How to replace the bundled Dart SDK in Flutter to run natively on Apple Silicon (ARM64)?

Asked 2022-Mar-21 at 16:27

Dart SDK officially supports ARM64 and as of now, 2.14.2 is the latest (stable) Dart SDK that has support for ARM64. Though it was the same version that was bundled in my Flutter setup, it seemed to run on Intel architecture (Activity monitor shows dart processes running on Intel).

I manually tried replacing the dart SDK on my flutter installation bu replacing flutter-directory/bin/cache/dart-sdk/ with the contents of a zip file of the Dart SDK made for ARM64, downloaded from dart.dev archive. But trying to run an app on an Android emulator (which runs on ARM64 and was working on my old Flutter setup), throws this error:

It seems it can't be used with Flutter yet, as seen in:

Apple Silicon support in the Dart SDK

[...] Note that the Dart SDK bundled in the Flutter SDK doesn’t have these improvements yet.

https://medium.com/dartlang/announcing-dart-2-14-b48b9bb2fb67

[Announcing Dart 2.14][ScreenShot]: https://i.stack.imgur.com/N8Qcc.png

And:

Get the Dart SDK

[...] As of Flutter 1.21, the Flutter SDK includes the full Dart SDK. So if you have Flutter installed, you might not need to explicitly download the Dart SDK. Consider downloading the Dart SDK if any of the following are true:

You don’t use Flutter.

You use a pre-1.21 version of Flutter.

You want to reduce disk space requirements or download time, and your use case doesn’t require Flutter. For example, you might have a continuous integration (CI) setup that requires Dart but not Flutter.

Android Studio Emulator in a Separate Window

Asked 2022-Mar-17 at 13:32

I'm having a problem with my Android Studio. This is the first time that I installed Android Studio. The problem is that when I install any devices it comes up with a grey background around the device or the emulator, I don't know if it has any thing to do with the latest Android Studio version, cause I have updated it, and the toolbar is at the top of the emulator instead of being at the top right of the device.

The first picture is how I want to be, and the second picture is what appears when I open Android Studio and run my app on the device (emulator).

Please help me out, I really need to fix this emulator screen.

Emulator is not working in android studio bumblebee

Asked 2022-Mar-09 at 09:34

I have run my app but still Device Manager is saying

No emulators are currently running. To launch an emulator use the Device Manager or run your app while targeting a virtual device

As you can see a green dot in the emulator that means "Emulator is running"

And some time emulator is showed but when I click on screen then emulator gone

I think this version of the android studio has more bugs when compared to its previous version

Do you guys have any tricks or solutions?

Any help will be is always appreciated!

ANSWER

Answered 2022-Feb-16 at 04:48

I have 2 Solutions so you can try both if one doesn't work

Solution No 1

Select device manager and select your device and select the drop-down menu

then click on the show on disk option

then delete all files that have the .lock extension and run your emulator again.

Solution No 2

You can get a normal emulator like previous time android studio have, so to get the previous emulator in the new version of android studio you can do these steps

open the settings tab by following the below steps or by pressing Ctrl + Alt + S

Select File > Settings > Tools > Emulator

then unTick the option name Launch in a Tool Window then click okay now you got the previous emulator. and if in the emulator you got any issues you can check This Solution for Emulator on StackOverFlow

Error when trying to run my React Native app on Android

Asked 2022-Mar-06 at 07:58

I've built my React Native app and tested and troubleshooted with my iOS devices for months. Now I'm trying to built and test the app on Android for the first time. The thing is, that I keep getting errors trying to run the Android-version of my app. After hours of debugging and troubleshooting, I tried to create a new RN project and see if that could run on my emulator and device. I got that part working and then I wanted to copy/paste the files of my existing app project into the new project.

I pasted my existing assets, styles, the source JS-files and the package.json file into the new project, ran npm install and then I ended up with the exact same error message as I had in the original project when I run react-native run-android.

The full error message is here:

I've hit this same issue and have temporarily resolved it by uninstalling react-native-video (npm uninstall --save react-native-video). That's not a great answer as I need that component, but I don't have a full solution yet. I think somehow com.yqritc:android-scalablevideoview:1.0.4. is required by react-native-video but has gotten lost or removed. Other thoughts are welcome.

UPDATE: Resolved! In your build.gradle in your Android folder you need to add the repository "jcenter()" in allprojects (not in build dependencies) like this...

How to configure proxy in emulators in new versions of Android Studio?

Asked 2022-Feb-23 at 14:14

Problem Description

I need to configure the proxy manually in my emulator through Android Studio. From the official Android documentation, it is suggested that this change can be made in the "settings" tab of the emulator's extended controls. The problem is that it seems to me that this documentation is outdated, as this setting is no longer displayed in the "settings" tab of the Android Studio emulators' extended controls.
