Answer 1

I was facing the same issue and below commands helped me to resolve it. Hope works for you as well. Firstly close your Metro Bundler and emulator, then try:

expo run:android

If it doesn't help go with:

npx react-native run-android

Answer 2

probably you are tring to use development build.

first start your expo app (-c for clear cache)

npx expo start -c

then press s (for switch to expo go)

now you can press a (for run android emulator)

alternative:

you can use --go option for start with expo go

npx expo start --go

NOTE

Same libraries not work on expo go and require development build. If you are using library like this first you must create a development build. (https://docs.expo.dev/develop/development-builds/create-a-build/)

expo start --android worked for me. This is assuming you're using expo of course.

Uninstall the application via adb:

adb uninstall com.reactnative02

Whis worked for me. – Bronchus

Answer 5

This happens when trying to build with EAS dependency. It's actually the switch of build types.

You can solve this by just running

npm start

and then

press s | switch to development build.

It's done.

Answer 6

if you are on expo and you are trying to build your app locally then you get this error follow the step below

1. run this command npx expo run:android this will create a new android folder in your project , don't panic your app is still on Expo
2. in the android folder ADD new file name it local.properties so in this new file paste this sdk.dir = C:\\Users\\PC-USER\\AppData\\Local\\Android\\sdk , replace PC-USER with your PC user name , then save it
3. stop the running process in the command line with CTRL C , then run this command again npx expo run:android.

thanks this is what works for me, it will surely work for you

Answer 7

In my case (expo), it was because my android phone was plugged when I pressed a to start the emulator so it was trying to run it on my phone which doesn't have the development build.

So I just unplugged my phone from the PC and did

npx expo start --dev-client

Answer 8

I don't know if that is your case, but this issue happened with me because I had to change the bundleIdentifier of my app. I did all the steps:

• Changed the bundleIdentifier on Info.plist and app.json files.
• Built the application again for the local profile with ios.simulator: true
• Installed the app on the simulator after the build (eas build command asks if you want to install it on the local simulator)

When I ran my app on the simulator I got the message: Device iPhone 15 (xxxxx) has no app to handle the URI: (my.old.scheme)://expo-development-client/?url=http%3A%2F%2F192.168.0.134%3A8081

I was running my app using the command npx expo start --dev-client --ios After adding the parameter --scheme (my.new.scheme) and forcing the simulator to open the new installed app (with the new scheme) it worked.

I hope that makes sense.
