Looking to create UWP APP using cordova.
The App needs to scan file system to get list of mp3 files on device, the device may be a desktop pc with windows 10 or a phone.
However the Cordova is able to see the virtual path and not C drive or D drive on device.
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);
The winPath of the received FS object is something like below
C:/Users/{USERID}/AppData/Local/Packages/{AppNameSpace}_bzbj8h50hftv4/LocalState/
And this is root of the FS, can not move directory to C: drive, it is not allowing.
So Question is, does UWP or any windows platform does not expose Storage devices to Cordova apps? Or I am doing something wrong, as I am new to Cordova development.
For full file access in a UWP app, you will want to add WinJS framework to your app.
The plugins are going to be targeted to cross-platform support, and mobile devices have more restricted file access. Running on full Windows, you will have more capabilities available, but likely not supported by plugins.
Look at http://www.buildwinjs.com/ for WinJS.

Currently,
My team and I are developping an Android Auto enabled app. And it appears to me this app is only available in my car unit, when I enable unknown sources in the Android Auto app.
However I'm wondering what defines an unknown source and how do I make sure my app is not an unknown source. Does Android Auto communicate with the Google Play Services for this or do i need to sign the APK with specific data?
How are you deploying your app? If you are deploying with Android Studio: as I recall you won't see it on your real automotive head unit, just the emulator. To show on the head unit it needs to be deployed in the Play Store, at least in developer and pre-release mode while under development.
First of all: Android Auto runs on your own device, meaning it adapts the same permissions you granted to particular apps. If your app doesn't have an app in the normal UI or you didn't open it on your phone once, then it would usually prompt you to grant permissions the first time you open it.
An unknown source is pretty much any way of getting your app outside of the Google Play Store (and OEM-specific app stores like Samsung App Store for Samsung devices etc.).
That is especially common if you e.g. download an .apk from the internet and want to install it, but your phone thinks their own file manager is an unknown source (because it is not intended to download apps).
I don't know if I'm allowed to ask this question but I really can't figure out how to use ARCore on Android Emulated Device.
According to the official guide I'm supposed to use API 8.1 on pixel/pixel 2 device in order to run any app which uses ARCore. Sadly those emulator don't come with the support for Play Store, and without Play Store I can't Instal ARCore on the device.
The device images that come with built in Play Store can't run ARCore instead. I'm really confused about how am I supposed to test anything for ARCore in this way.
I need it to develop an app for a University program and I need to become familiar with Augmented Reality Development but I can't even get started because of this issue.

For using ARCore Emulator, at first, you have to create a virtual device with support for AR. I'm running Android Studio Dolphin | 2021.3.1 on macOS Monterey 12.6.
I created Pixel 6 Pro virtual device:
ARCore's targetSdkVersion has been set to Android API level 33.
Here are the steps you have to make in order to get a working Emulator:
Set up Android Debug Bridge. I set up adb for Mac.
Download Google_Play_Services_for_AR_1.34.0_x86_for_emulator.apk from GitHub repository.
Run your AVD.
Type in Bash Terminal the following command (to be sure that the port is 5554):
adb devices
Result:
// emulator-5554 device
Go to the folder where Google_Play_Services_for_AR_1.34.0_x86_for_emulator.apk is located. For instance:
cd ~/Desktop
To install Emulator, type in Terminal the following line, while the virtual device is running:
adb install -r Google_Play_Services_for_AR_1.34.0_x86_for_emulator.apk
Repeat previous steps for additional AVDs you’d like to use.
Delight!
P.S.
Take it into consideration: Android Emulator does not support such ARCore APIs as: Depth API, Geospatial API or Augmented Faces API. That's because Emulator doesn't have corresponding sensors. When any of these features are enabled, the Emulator picture can't render correctly: a screen will be entirely black, although UI elements drawn on top of the Emulator picture still be rendered.
Sergei's answer was right at the time, but the version of the ARCore app in his link (v1.1.0) is now too old. The following worked for me (after many false starts):
VIRTUAL DEVICE SPECIFICATIONS
Device: Pixel API 27
System image: Oreo / API Level 27 / ABI x86 / Android 8.1 (Google Play)
LINK TO ARCORE APK:
https://www.apkmirror.com/apk/google-inc/arcore/arcore-1-5-18091013-release/arcore-1-5-180910139-android-apk-download/download/
Download the ARCore APK to your desktop. In Android Studio, set up and then start the virtual device as specified above, open the Play Store app on it and sign in. Then drag the ARCORE APK file onto the virtual device; it should silently install. Finally, run hellosceneform on the virtual device.
Just install to emulator ARCore_1_1_x86_for_emulator.apk. Just drug to emulator. Check this link https://github.com/google-ar/arcore-android-sdk/releases/tag/v1.1.0
I need to find the app data folder of a Windows 10 UWP app from within a Win32 app or powershell script (not sandboxed and sufficient privilege). If I know the AUMID, is there a way to find out where the sandboxed app files are installed?
Found the answer:
From the command line: cd %LOCALAPPDATA%\Packages\AUMID
I have a Xamarin app that runs on Android, IOS and Windows 8.? It is essentially a “player” to display a proprietary document format. Formatting the documents so they look good on a small screen is a trial and error process. Essentially: Edit; Compile; Transfer to mobile; View; repeat;
To speed up this process, I am trying to build an emulator. I am using the Windows version of the app as a base for the emulator (because if I stay in Xamarin, I don’t have to rewrite all the code for Windows Forms)
The compiler is a Windows app. After compiling I know exactly where the file is located. When I run the emulator, it does not give me access to the Windows file system. I tried using PCLStorage Library. It stored the file here:
C:\Program Files\OpenSSH\home\30011765\AppData\Local\Packages\85930d70-750c-41a6-9b95-03faaed4159c_nh7s0b45jarrj\LocalState\ZDO\dev
I specified this part \ZDO\dev but have no idea how it selected the rest. Like why OpenSSH?
Question: Given this app is only going to run on Windows, is there a way to load a file as C:... ?
If not, is there another way for a Windows Forms App to share a file with a Xamarin Windows App?
I’ve spent several hours searching for a working example solution and have yet to find one.
I need to get video that has been recorded by my app to isolated storage.
Is this possible?
Or I should save my recorded video to some 'shared' place?
IF you want to get a file of an app that you have deployed on your device (that is not installed from the windows store), you can use the command line tool ISETool which is installed with the windows phone SDK, or if you want a User interface you can use IsoStoreSpy.
