I was trying execute myapp to android but an error occurred.
To clarify what happened, first time I install nodejs and Android Studio.
Later I used the following commands:
npx react-native init 'app'
cd app
npx react-native run-android
Its my fisrt time messing with react native, I was following this page:
https://learn.microsoft.com/pt-br/windows/dev-environment/javascript/react-native-for-android
And the error is:

I want coding in real time for android app.
How can I fix this?
Looks like the terminal output gives you several steps to do/check.
Make sure you have properly set up your android environment. Use this link to do so. You can use Expo-Cli or React-Native-Cli.
SDK location not found. This could be an off-shoot error of not properly doing step 1. However, to cover all of your bases, ensure you have properly set up your Android Emulator. This doc is a great walkthrough.
Once your Android studio and AVD Manager is properly set up, and your development environment is properly set, you should have no issues!
Please let me know if doing the above to steps did or did not solve your errors.
If you follow the steps, https://reactnative.dev/docs/environment-setup and https://developer.android.com/studio/run/emulator there will be no problem.
As a React Native fan on Windows 10, I'd like to mention just few points you need to check.
First, please check following user variables in Environment Variables ( You can see it from System Properties).
adb="C:\Users{username}\AppData\Local\Android\Sdk\platform-tools"
ANDROID_HOME="C:\Users{username}\AppData\Local\Android\Sdk"
JAVA_HOME="C:\Program Files\OpenJDK\openjdk-11.0.15_10"
Path: check if contains {ANDROID_HOME}\platform-tools
Eg:"C:\Users{username}\AppData\Local\Android\Sdk\platform-tools"
Second, if you are using Android Sdk emulator, please make sure that it configured correctly in emulator list in Android Studio.
For an instance, I created a android emulator using android sdk-29 and you can check the followings.
Third, I recommend you, deploy first app on emulator in Android Studio.
Because we need to download gradle zip file and others, it's essential to run your first android app in Android Studio.
When you confirmed your first android app(Deploy empty project app is also okay), you can run your React Native App by Expo-cli or react-native-cli.
I have a react native app that builds and installs successfully. However, it does not run. When I click to open it, it shows a white screen for a second then closes itself. Attached is a screenshot of the terminal when I run react-native run-android
Has anyone ever encountered this problem and how did you solve it?
Its possibly related to native side errors you can debug that by using android studio and try running the project in studio you will get the errors in log cat of android studio
I created a new project at Expo, after which I was already building it using expo buildbut over time I needed to move away from Expo a little and execute an expo eject, and then continue development on regular React Native.
I ran into the following situation: I am trying to build an apk file with the ./gradlew assembleRelease command, but I get a debug build instead of release, I don’t understand why this is happening, I tried to follow the build instructions specifically for the release version - unsuccessfully.
I also tried to create a new project without using Expo - the whole scenario described above worked correctly and I got a release build of my application, and with all that, I compared the android/app/build.gradle files in these two projects and they are almost identical in terms of their configuration.
My main task and problem is to build the release version of the apk file and understand why, with different attempts to build, I only get the debug apk.
I have an issue with react native release APK.
The app run on debug mode but it crash immediately on release mode
Is that app running without any warnings/errors before building the APK?
The error message clearly says that it can't find a variable, maybe it got deleted or modified.
You can cross-check the app once by going to the development mode and see if you get the same error.
Try out clean your gradle and make the apk again.
I am using this package https://github.com/evollu/react-native-fcm
I complete the installation process. The project is working. But every time I turn it on project. I am working ./gradlew clean on console. Other than that, I get the following error when I run
You can delete build folder, and recompile project again.
