I am getting this error on Android simulator:

React Native version mismatch:
Javascript version: 0.58.5
Native version: 0.59.5

I have upgraded React Native, modules, Android studio and pretty much everything i could. Everything works fine on iOS, this happens only on Android. Build is succesful

I have tried closing all terminals, yarn install, creating new android device. I am guessing it has to do with actual version of the React Native in Package.json, but it is the 0.59.5 and when I searched whole project I cant find any reference to 0.58.5 anywhere.

• javascript
• android
• react-native

• can you try removing node_modules folder and package-lock.json files before running yarn install? – kenmistry Commented Apr 25, 2019 at 1:47
• 1 close your terminal and run again. it's working. – Kirit Modi Commented Apr 25, 2019 at 3:16
• just close the app on the emulator and rerun it from expo ui. – Junius L Commented Apr 25, 2019 at 6:32

• @kenmistry if i will remove the node_modules folder, will i have to reinstall all the modules again ? I mean all the setup when doing first time installation of a package ? – CosmicSeizure Commented Apr 25, 2019 at 10:18

I fixed the problem with help from github forum. This error was caused in my case by having Android 9 in simulator. Installing new device with Android version 8 fixed the issue.

Close all terminal and IDE and Launch it again. It will work

Try following :

package.json

"react": "16.8.6",
"react-native": "0.60.4",
"react-native-maps": "0.25.0",

build.gradle :

googlePlayServicesVersion = "15.0.1" 
 androidMapsUtilsVersion = "0.5+"

I had workdir/android/app/src/main/assets/index.android.bundle left from the previous build from another branch where I used older RN.

Running react-native bundle --platform android --dev true --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res fixed it for me.

Make sure you have RN versions in package.json same as it is in android/app/build.gradle, it should look like:

in package.json

"react-native": "0.59.5",

and in android/app/build.gradle

implementation (".facebook.react:react-native:0.59.5") { force = true }

Edit: Can you please also check that the packager and the emulator/device are in same network and the JS bundle is fetched from right locations ? It seems your application is not getting updated while building, it is stuck in the old code.
