How to brake network capabilities of an apk? Not installed app - android-studio

Am trying to disable all network capabilities of an app. I know how to do it in settings but i want to brake all online service of an app on apk. so that even if i share apk of that app with someone else they won't have to disable network of that app manually. I am slightly familiar with Android studio and java.

Try lucky patcher app. It's not available on Play store.

How to send a Unity HoloLens 2 project for immediate testing by a remote colleague (without certification from Microsoft Store)

I am developing for HoloLens 2 and I don't have the device (I am using the Emulator to test).
I want to build the project with Unity and send the built package to a colleague that is not a developer - meaning, he is not good with Visual Studio - and who wants to test the app.
I tried using Microsoft Store and this worked for the initial P.O.C., but after the second submission I thought that it was going to be faster, but always takes up to 3 business days, which is not acceptable as a good workflow.
I know that, in ideal conditions, I should have the HoloLens, but this is not possible for now.
Do you have any idea on how to send packages to a non-developer person so that he can test the app in another country and so that it doesn't require a certification process like Microsoft Store?
You can take a look at the Sideloading feature provided by HoloLens Device Portal. Please follow this guide to connect the HoloLens over Wi-Fi or USB and manage your device from a web browser on your PC: Installing an app. In this way, you can directly send the app package to your colleague, and he can install it without using VS.

Finding Hololens App AUMID for Kiosk Mode

I am trying to set up multi-app kiosk mode on a Hololens headset and allow access to an app that I will be sideloading onto the Hololens. I've been using these guides to try and create a provisioning package, but I'm stuck on the part where I need to provide an AUMID for the app. This page is only useful for finding the AUMID of an app installed on a computer, how can I find it for an app installed on the Hololens, either once it is installed (using device portal), or from the finished Unity build or app package that I can generate from it?
I found an answer for this today as I was having the exact same problem.
Device portal is the best method for HoloLens that I know of.
Let's say you wanted Feedback Hub in your Multi App Kiosk.
You go to Device Portal > Apps > find your app in the drop down (in this example, feedback hub)
PackageFullName: Microsoft.WindowsFeedbackHub_1.1903.2331.0_x86__8wekyb3d8bbwe
Then you remove the version number and the build architecture. As well as extra underscores.
Microsoft.WindowsFeedbackHub_8wekyb3d8bbwe
Finally add on the !App
Microsoft.WindowsFeedbackHub_8wekyb3d8bbwe!App
If you find a way to find the AUMID from Unity before it's installed I'd like to know it.

Android Studio app for beta testing on Play Store

What all is required to upload Android Studio app for beta testing on Play Store? Will I need the google developer account, screenshots of the app and detail about the app ?
You will need all the things you listed above and more. Here is a website that can help you with beta testing: Set up an open, closed, or internal test
Yes, you must need developer account(20$ approx.), screenshot of your app.
Rest of the things like available country, beta testers etc...., will be configured later with your account.

uploading .ipa file for appcenter distribution using Xamarin

I am trying to use AppCenter to distribute my app to iOS beta testers.
I have included the nuget packages for Microsoft.AppCenter and Microsoft.AppCenter.Distribute
I followed the developer.xamarin instructions for creating an IPA
An IPA did not appear in the Bin > iOS Device > Ad Hoc (or Release) folder as expected. An application (.exe) file was created.
This is most likely the area I need help on.
In AppCenter I selected Distribute and got to the Upload a Build screen, I could not find an IPA file on my computer.
when pressing the Where Can I Find my IPA file? link, I was transferred to https://openapi.appcenter.ms/, which I didn't understand how to use to find the file. Perhaps this link is incorrect or someone can tell me how to use these apis to find the file?
I have never connected my Windows Visual Studio Xamarin to a Mac. LivePlayer on an iPhone works beautifully. I was hoping to get to be able to distribute my app without using a physical Mac.
Thank you for any help. If you can point me towards other tutorials on setting up and using AppCenter to distribute to iPhone beta users, I would appreciate it.
To order generate an .ipa file for distribution a Mac needs to be involved in the build process.
If you do not have access to a Mac for local development and the application source code is located in a git repository hosted in GitHub, BitBucket, or Visual Studio Team Services, then you can link App Center to the git repository and configure App Center to perform the build for distribution purposes.

Error while create a new react-native project

Trying to create a new app on react-native. 'react-native start' command gives no error. But I'm not able to see my app on the emulator. Can anyone help me in figuring out the problem. I'm new to react-native.
Are you using a Macbook or Windows? For Windows, you will have to use an Android emulator, thus you will need to download Android Studio, and the Android SDK.
For Mac, you will use the IOS emulator, you will need to download Expo in that case.
Also you could try using the create-react-native-app instead. I built a project with 3 other buddies in two weeks, we found that it had the most reliable boilerplate and is really good for beginning with react-native.
*** Edit:
*** Big caveat with create-react-native-app is that it won't matter what OS your computer has. If you have an apple phone, you just run "npm run ios" then scan the QR code with expo. If you have an Android phone like I had...you will run into a few issues where you need to set the phone to USB debugging mode in the developer's settings, download the USB debugging driver for your phone's model, ensure both your phone and computer are on the same wifi network, install expo, and finally be able to run "npm run android".
I was the only one on my team developing with an Android phone, so if you need advice on that, feel free to ask.
Some extra information about create-react-native-app is that it allows you to code for both Android and IOS phones by using the same project folder, rather than having to adjust settings for one platform at a time.
That has it's pros and cons for sure and there will be little differences in how one platform functions over the other...so my recommendation is to build for one platform at a time, focusing on whichever one you are testing on.
Since you're using Ubuntu
