Android Studio 3.3 Signed APK Option Missing - ionic4

I'm trying to publish my Ionic 4 app into Play Store through Android Studio and the option to build to a signed APK is missing. I know there are similar questions to mine already asked here, but their answers are directed for previous versions. I have spent many hours searching through websites and I have typed lots of command prompt commands, such as
ionic cordova build android
and
cordova build --release android
I went to build and did the signed APK a few times, and it gave me a small window about "required updates."
I agreed, then it restarted, and after I went back to build and the option was missing! I tried installing and reinstalling Android Studio. I want to be able to create a signed APK and publish my app to Play Store. Where is the missing option? Please help me figure out how to turn on this feature in my Android Studio version 3.3.2.

Thanks to CodeChanger. Run the emulator, then restart the app. The Signed APK option will appear.

Expo React Native building apk

I have been trying to build my apk today but I always face this problem. After completing the build, i download it to my phone and i cannot open it. However, this was not the case 2-3 days ago. I had no difficulties or errors in Run expo doctor. I was able to download the apk to my device and test my app.
I am not really sure what to do and any help would be appreciated.
This is what I got after running npx expo doctor:
I managed to solve my problem. I used Android Studio's logcat feature and when I ran the app on the emulator I found the issue - it was related to admob. At this point, I dont need admob, so I deleted its folder from my project and everything was fine after this.
Running expo doctor usually ends up in flagging what dependency needs to be upgraded if the jump to automatically update it goes into the majors like in your case from 4 to 5.
Maybe try upgrading #expo/config-plugins by using expo upgrade or commands from your preferred package manager.
If that’s impossible due to other packages depending on the specific version, maybe consider adding overrides in your package.json. Here is a helpful article about that.
In my experience this may not be the only reason for the crash of the app. Try running the app consecutively about 3 or 4 times even if it crashes and I believe Android will prompt you to submit a bug report and maybe show you the call stack it failed at.
Let us know how it goes.

Impossible to update expo project inside Expo Go after switching to EAS Build

I have the need to run a project from Expo Go without being connected to PC. We are developing an app that require GPS and needs to be tested in open field.
Before EAS became the standard to create projects i used
expo build:android
ad this created not only the apk, but uploaded the project to my account and i was able to start it from Expo Go projects section just like the app was installed on phisical device. That worked also fo iOS and was a great testing feature.
After i moved to EAS Build
eas build -p android --profile preview --clear-cache
my project inside Expo Go does not update anymore and its stucked at sdk 44 even if now i'm working (and creating builds) with sdk 46.
I went through the official documentation many times but i don't get how to make the app start from Expo Go (project sction) as i did before. Maybe i'm missing some configuration.
Thank you all for any kind reply.
Have a good day.
EDIT
I found the solution to this problem and now my builds are working and uploading to Expo Go.
Check out this information: https://github.com/expo/fyi/blob/main/eas-build-archive.md
Basically EAS Updates will not bundle anything inside your .gitignore, in my case it needed specific config files. Did a quick test by taking them off the .gitignore and now it's working. Will move to GitHub SECRETS in the future.
Hope that helps.

compile apk on a folder "Android" already created previously in react-native

I'm new to react-native, I've seen tutorials but everyone uses expo. I downloaded this project where they don't use expo. I want to compile this application for android, to finally get an .apk
This application already has a folder called "Android" but inside it does not have its respective .apk. How can I generate it?
this is the repository:
https://github.com/zsajjad/BusinessCard
It would be great if you can attach screenshots of how I should do it
Note. I have the latest version of android studio and I don't see the option of "build"
commands like "gradlew" from the console, they don't work, it's as if I didn't have that command installed
Following instructions for build apk using android studio
Hope you installed node and react native on your machine. If not
please follow the link to install it.Install node and react native
open your command prompt or terminal and redirect to your download project - cd /Businesscard Master (change it according to your project location)
Now enter - npm install
Enter - react-native link
Follow the android related linking instructions on following link react native camera
Hope you know about android camera and storage permissions.
same thing for react native text detector. Because your downloaded project have that packages in package.json
Now open your project android folder in android studio using open existing android project.
Then select build your project from android studio build menu and run it also
Generate apk using build menu- same process you have to follow for native android project
You don't need to use the CLI, that's needlessly complicated and it obscures what Android Studio is actually doing. Here's all you need to do.
Open the whole /Android/ folder in Android Studio. This is your "project" similar to how you open a *.xed file in XCode. Except in Android Studio, you just open up the whole folder to get the build.
Android Studio will now prepare your project using Gradle. If there are any errors in the preparation it will tell you about them. Assuming your gradle and Android Studio versions are compatible and you got no errors, you're now ready to emulate, debug and create a production build. At this point the workflow is similar to using XCode. You'll see emulators under Tools -> AVD Manager.
In the file menus go to Build->Generate APK. You can choose between signed APKs, debug APKs and so on. You'll need the key file if you're signing the APK on your computer, otherwise there's also Google Play signing after you upload the APK.
TL;DR: Just open your /Android/ folder in Android Studio.
Side note: When Android Studio gives you popups to upgrade stuff don't do it. NEVER upgrade Gradle or Android Studio unless the RN / Expo team specifically ask you. This will break your whole project and you will need to rebuild the platform.

react-native create app hangs while create

I use react-native with actual version and have tried to create a simple project. But while trying to create it by using
expo init AwesomeProject
the whole process hangs.
I have tried to look for a solution by searching on the internet but without any luck.
The error could be seen in the following screenshot:
That error generally means that a file is being accessed by two different things at 'around' the same time. And 90% of those times it is because of an anti-virus or similar.
Its a permission error, so my advice, try to do it after a fresh reboot and boot the powershell as admin, disable antivirus etc..
If still does not work reinstall nodejs/npm.
I had the same experience. The project gets created using React-native. When you try to run it, the 'Metro' interface comes up. There is an android phone on the USB drive which has previously been used to run Android Studio created projects successfully. However, on the command shell the app hangs in Metro.
While trying to run the project from Android Studio snow cat, there are build errors (red) in the App manifest file and there is this exception.
Build failed due to java.lang.NullPointerException
Installed expo-cli (C:\Reactive-native>npm install -g expo-cli). The app fails to run and hangs on the connected Android phone(Samsung 21) using the Expo Go client. This client has no problem having been tested in Snackbar.
I have a question in the Expo forum and probably someone will answer!

Apache Cordova not Allowing me to run in visual studio

Every time i try to create a new app ( trying to look at cross platform apps) in visual studio I get this error:
I have installed the android SDK , is there something else I should be installing?
Thanks
It seems you installed the android SDK but didn't run it to install the platform tools and the SDK APIs.
Run the "android" command on your computer, it will start the android SDK manager.
Then you have to install The android SDK tools and android platform for at least SDK 19.
One quick way is to just click the install button on the bottom right of the window, it should install automatically the latest SDK tools and paltform tools.
If you're short on disk space I recommend you uncheck all that's not usefull if you only want to use Cordova and not plan to do native dev :
the samples
the system images (unless you want to use the emulator, in this case just install one, don't need all)
the documentations
This is simply telling you that the x86 emulator system image is missing. If you do not plan on using the Android Emulator or will only be using an ARM image, you can ignore this warning. We're working to ensure messaging is more nuanced in this area in the future.
