Yep seems to fail with react-native v 0.58.2 as well

If you add this line resValue "string", "build_config_package", "YOUR_PACKAGE_NAME_IN_ANDROIDMANIFEST.XML" to your defaultConfig, you should remove it.

I'm having the same problem on Android. Anyone found a solution? In BuildConfig the variables are present but not when reading from Config (in js). iOS works.

[Samykills]

this problem is related to JAVA version in your system, i was running on java 9 and it was'nt ./gradlew clean or assembleRelease were not reading the passed environment file, then i downgraded to java-8 and it worked like a charm.

java -12 gave a new error so i avoided that!

in my case, it didn't working because i had this in my react-native.config.js:

module.exports = {
assets: ['./src/assets/fonts'],
dependencies: {
'react-native-config': {
platforms: {
ios: null,
android: null,
},
},
},
};

By removing android: null, it works fine on android :)

@Sathyanarayan09 @Samykills what version of react-native-config are you using?

I have:
"react-native": "0.59.8"
"react-native-config": "0.11.5"

and works great.

"react-native": "0.59.8"
"react-native-config": "0.11.5"

I get Reading env from: ../../.env with no errors. But my config is always empty.
works fine on iOS

IOS works fine..

react-native: 0.59.1

Hi everyone.

After seeing "react-native-config" stop working on Android, I started investigating why.

I have seen many comments with the same problem as described by @Sathyanarayan09 .

Only in Android, the plugin does not read my .env files (in my case .env.prod .env.staging .env.dev correctly declared in "project.ext.envConfigFiles").

I finally found my solution.

If in Android Studio -> Edit Configurations... -> Tab General -> Installation Options, I have "APK from App Bundle" option selected, just don't read my .env files.

But if I use the "Default APK" option, it works correctly again as it always did. Weird...

I hope it helps.

@Sathyanarayan09 I might be wrong but I think react-native-dotenv only works for your JS, so the variables are not accessible from native code files

For anyone struggling with this, I seemed to fix this (🤞🏻) by adding resValue "string", "build_config_package", "com.blah.blah" to my defaultConfig in app/build.gradle.

The instructions suggest adding resValue "string", "build_config_package", "YOUR_PACKAGE_NAME_IN_ANDROIDMANIFEST.XML, but for some reason this didn't work with the .xml on the end

See troubleshooting https://github.com/luggit/react-native-config#problems-with-proguard here.
It works for me on react-native: 0.61.2
and don't forget rename mypackage in com.mypackage.BuildConfig.

I use "react-native": "0.59.1"
react-native-config doesn't work on android's bundleRelease, it seems like it is very fragile library.
To fix the issue - remove react-native-config and instead of ENVFILE=.env.prod use echo 'export default "prod"' > src/env.js and config.js:

import env from './env.js'
var config = {
  dev: { host: 'http://localhost:3000/'},
  stag: { ... },
  prod: { ... }
}
export default config[env]

It works for me.
