How to make executable metro style apps? - xaml

I Created Metro style Application ,and i want to make it executable so that i can run it on devices that have windows 8, is there any tutorials or tool that make that?

You need to package the app (Project -> Store -> Create app package) to either upload it to the store or use it locally, the second being what you want. The computer you want to run the app on then needs to have a developer license.

how could we access the images located outside the expo project?

I created a mobile app by expo (react native), I would like to display profile image, knowing that the images are located outside my project.
when I want to access any image I do not get there, and I get this type of error
"SHA-1 for file (D:\Workspace\ImagesProfile\images3.jpg) is not computed".
this is the hierarchy of my workspace.
-Workspace
--ImagesProfile
--Myproject
Pleace how can we solve this problem?
The way the react-native packager works right now, it's just going to scan the roots of your project and below when creating the JavaScript bundle, so it will be really hard to do this.
You basically just need to put the files under the root of your directory. There are some tools out there for syncing files from another directory into a directory under the root so you could use one of those if you really need to.
Some people are working on ways to make symlinks work with this. Notably, you might look at Haul from Callstack. https://github.com/callstack-io/haul But that isn't integrated into Expo yet.
Okay at first you should understand what you are doing. You're creating a react native application, which means this application is running on external devices and not on your PC. Your simulator or expo client running your application encapsulated from your PC using only project files. When you wanna use external images in your application you need to host them. You can create a local docker instance as image server ( e.g. an express application with a static folder ).
To make it clear, it's not possible to use images inside your filesystem which are not a part of your react native application. You can use external image server like "imgbb" for test purposes, but it's not recommended to use them in your final version.
Happy Coding!

How to fix optimazition error publish in play store

my apk is 1.4MB but error is "This APK results in unused code and resources being sent to users. Your app could be smaller if you used the Android App Bundle. By not optimizing your app for device configurations, your app is larger to download and install on users' devices than it needs to be. Larger apps see lower install success rates and take up storage on users' devices."
how to fix this error
It's only a warning, not an error.
For an app that small I wouldn't worry.
It's not something that's made its way into the Ionic ecosystem yet but I heard that if you open up your project in Android Studio and then do the build through there you can create an app bundle.
I'm not totally sure that its fully tested for Ionic so you might have issues with this, but Android have published a full guide:
https://developer.android.com/guide/app-bundle#get_started
This is what they say:
Download Android Studio 3.2 or higher—it's the easiest way
to add dynamic feature modules and build app bundles.
Add support for Dynamic Delivery
by including a base module, organizing code and resources for configuration
APKs, and, optionally, adding dynamic feature modules.
Build an Android App Bundle using Android Studio.
If you're not using the IDE, you can instead build an app bundle from the
command line.
Test your Android App Bundle by using it to generate APKs that
you deploy to a device.
Enroll into app signing by Google Play.
Otherwise, you can't upload your app bundle to the Play Console.
Publish your app bundle to Google Play.

Deploy UWP to windows phone stopped working

I'm building UWP application and deploy it to a lumia930 for testing.
I just click
Store => Create app packages => No Windows Store => Auto increment
version and Create.
When finished the whole app packages is copied to the phone and I install the certificate and the program.
It used to work fine but suddenly the program didnt show up anymore in the apps list. The current version is 1.0.31.
What can I do to fix this?
On the phone devices, you need to manually install all the dependencies from the Dependencies/ARM folder of your app before installing the appxbundle. Failing to do so will result in a silent failure of the installation.
Another option is to turn on the device portal on the phone from settings > update & security > for developers.
One done, get the displayed url and open it from your computer web browser. Under the apps section, you will find the "install app" subsection which will properly deploy the application. you will have to manually declare the dependencies.

CLI support for App Store app

Is there a way to add a command line interface to a sandboxed app downloaded through the Mac AppStore?
Something similar to the XCode command line tools, do not just use the whole executable name and path.
This can't be done - app store rules don't allow to install code outside the app bundle. If you want to provide your users a CLI interface you'll have to make this available as a separate download outside the app store.

Strange Issue: Application does not show in Main Menu after installation

I am developing an application for Symbian S60 V3. The application can be run properly on Simulator on PC. It can be transferred to Phone. On Phone, it can be clicked to installed. But after installation, I cannot find the installed application for running. It just disappear.
Is there any hint ?
Did you create the application with user interface? If it's just some bacjground process without icon and GUI then it won't be visible.
Did you check under Applications link (or Installed or whatever it is called in different systems).
Do you see your app listed in Settings -> Application Manager?
