The development client (com.reactnative02) for this project is not installed. Please build and install the client on the device first

Question

I am getting the above error when previewing the react app on an android studio simulator. Please help. Here is the error:

"CommandError: The development client (com.reactnative02) for this project is not installed. Please build and install the client on the device first."

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/)
