I am using react native and try to create an apk file with "eas build -p android –profile preview –clear-cache"
On https://expo.dev/ I see the following gradle build error.

`> Task :app:processReleaseResources
FAILED
FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:app:processReleaseResources’.

metro.config.js:

const { getDefaultConfig } = require('expo/metro-config')

const defaultConfig = getDefaultConfig(__dirname)

defaultConfig.resolver.resolverMainFields = [
'sbmodern',
...defaultConfig.resolver.resolverMainFields
]

defaultConfig.transformer.getTransformOptions = async () => ({
transform: {
experimentalImportSupport: false,
inlineRequires: false
}
})

defaultConfig.watchFolders = [...defaultConfig.watchFolders, './.ondevice']

module.exports = defaultConfig

I could not found a solution and I have no idea how to fix this.
I tried to remove folder node-modules and did a npm install but did not help.

  1. remove the splash property content from ios and android and place it in on top in the app.json file.

    after that run "expo prebuild"

    after that run "expo run:android"

    test it!

  2. Sorry for mine five cents but an error message say that color "splashscreen_background" doesn’t define in resources. Just find a file values/colors.xml and add missed value.

    Below an example of file content

    <resources>
      <color name="colorPrimary">#023c69</color>
      <color name="colorPrimaryDark">#ffffff</color>
      <color name="splashscreen_background">#ffffff</color>
    </resources>
