I have built an android app using expo build:android for a react native project. And then I can't ran the .apk on my 2 android phones. Error message App not installed was shown after ran the .apk on my phones.
I tried to rollback to older versions of my code and I found that the .apk can ran after I used the old slug value in app.json
I installed the .apk at android emulator. Error message The APK failed to install.
Error: INSTALL_PARSE_FAILED_NO_CERTIFICATES: Package /data/app/vmdl1022936792.tmp/base.apk has no certificates at entry AndroidManifest.xml is shown.
Having no ideas why this happens. How I can use a new slug value and build a valid .apk via Expo?
I feel code signing is the problem, the app is not able to install on another android only for this reason.
Use this link
https://docs.expo.io/versions/latest/distribution/app-signing/
try using command
expo build:android --clear-credentials
I have created one react-native app using expo and atom editor. It's running fine in android device and iOS simulator but with the help of expo. What I want is to generate Apk(debug) so that I can directly run on device. How can I do it ? I followed this(Dmitry Mugtasimov's answer). should I run all those command inside project folder ? Also I don't find index.js file inside my project folder. Also if someone know how to run on iOS simulator by creating app like file(don't know what is that in Ios because from android background). Please help, thanks
Since you have used Expo to develop your react-native app you can build the android app by going to the project folder and running the bellow command in the terminal
expo build:android
The building process will take around 5-10 minutes. When your build is done, expo build:status will give you your .apk file url. If not, it will say your build is still in progress and to try again later.
Also to build the iOS app you can run,
expo build:ios
To build the iOS standalone app you will need to have an Apple Developer account, but for Android standalone app you don't need a Google Play Developer account.
For the above commands to work you need to have expo-cli installed, For this you can run the bellow command,
npm install -g expo-cli
More Info: https://docs.expo.io/versions/latest/distribution/building-standalone-apps/
If you don't have an Apple Developer Account. You can build the iOS
standalone simulator build using the command,
expo build:ios -t simulator
And then wait for build to finish then download and unpack YourAppName.tar.gz. Then, start the iOS simulator and run xcrun simctl install booted YourAppName.app to run the .ica file.
More info: Expo / React-Native, Is it there a way to test-run standalone iOS apps on a device/simulator?
i am using create-react-native-app
there is no android / iOS folder
how to generate signed apk and deploye to google play store
Here are the instructions for create-react-native-app app deployment.

If you want to build and deploy your app yourself, you'll need to eject from CRNA and use Xcode and Android Studio.
This is usually as simple as running npm run eject in your project, which will walk you through the process. Make sure to install react-native-cli and follow the native code getting started guide for React Native.

If you don't see android/ios folders in your directory. Then type in your terminal react-native upgrade then react-native link
I built a test application using react native. I'm trying to publish it following this tutorial: https://facebook.github.io/react-native/docs/signed-apk-android.html
However, my project does not have folder android. How can I create this folder?
In React-native, there are two method to create Singed APK File
First you should know
it's best to create apps using react-native init rather than expo as React-Native-Cli gives you local project for both ios and android,you can test and debug the code locally and also use the tool to publish applications
- If you create the project by using this command -
react-native init Project_Name
Then follow this method.
BUT IN YOUR CASE
you're using expo and also expo-cli! that's good! but when i use expo i usually like to go with expo XDE which has single version to publish,render or debug with it's own console in the bottom and that'll help you upload your code to expo server where you can ask them to render app for iOS or android and they will return you a link which will download the APK or the ipa file for android or iOS respectively
Here is the documentation link which'll explain you each step one by one and do keep an eye on the notes and TODOs while following the step (in your scenario)
- If you use expo,for create React-native project
then follow this method generate the singed APK file for Android - Expo
I am an android developer and learning react native.
I made an app in React Native and now I want to release my app in android play store and apple store but I don't know where do I put my react native project code/files?
I had put react native code in my PHP(Linux) server but it's not working, it says file not found 404.
please guide, Thanks
You need to generate build standalone signed apk.
Generating Signed APK
https://facebook.github.io/react-native/docs/signed-apk-android.html
1) first create keystore file and put in android folder location
2) setting up gradle for keystore
3) run comman
react-native run-android --variant=release
after success run command you will file apk-release.apk in andorid/app/build/outputs/apk/ location
then you can uplaod apk to app store
If your app doesn't need detach (for example doesn't use bluetooth) you can use create-react-native-app and put your app code inside new project. That way you can publish your app to https://expo.io/ . It's a great way to publish your app without Google Play and App Store.
Here is instruction for creating new react native app with expo kit:
https://facebook.github.io/react-native/docs/getting-started.html
And here is how to publish it into expo:
https://docs.expo.io/versions/v25.0.0/guides/publishing.html#how-to-publish
All you need is create-react-native-app and exp command line tools.
