Hello my friends!

I’m learning react-native and I’m have a problem with build apk from expo.

I’m received a exception:

and i dont know what to do anymore.

I tried alter this file but didn’t have result.

Can you help me?

My build url:

My app.json:

“expo”: {
“name”: " Mudarja app",
“slug”: “mudarja-app”,
“privacy”: “public”,
“sdkVersion”: “34.0.0”,
“platforms”: [
“version”: “1.0.0”,
“orientation”: “portrait”,
“icon”: “./assets/icon.png”,
“splash”: {
“image”: “./assets/splash.png”,
“resizeMode”: “cover”,
“backgroundColor”: “#FFFFF
“updates”: {
“fallbackToCacheTimeout”: 0
“assetBundlePatterns”: [
“ios”: {
“supportsTablet”: true
“android”: {
“package”: “”,
“permissions”: [

Thank you.

You are missing an “F”. There should be 6 of them.

Omg, i’m very thankful because that was it!

thank you my friend.


The error message mentioned an “invalid color”. Certain colours are specified in app.json so I focused on the backgroundColor in your app.json. :slight_smile:
