React-native-config: BUG ANDROID

Created on 24 May 2017 · 11Comments · Source: luggit/react-native-config

IOS it ok, but android not ok.
my file .env
URL=localhost:3000

I used to "import Config from "react-native-config" in js code
-> IOS then Config = {URL="localhost:3000" }
-> Android then Config = {}

Allright, following the above suggestions + adding this line to android/app/proguard-rules.pro solved it for me:

-keep class com.mypackage.BuildConfig { *; }

(where com.mypackage is your package name)

Basically following the readme in other words 😄

So to recap:

In android/app/build.gradle (right after apply plugin: "com.android.application"):

apply from: project(':react-native-config').projectDir.getPath() + "/dotenv.gradle"

In MainApplication.java:

import com.lugg.ReactNativeConfig.ReactNativeConfigPackage;

@Override
protected List<ReactPackage> getPackages() {
  return Arrays.asList(
    ...
    new ReactNativeConfigPackage(),
    ...
  );
}

In android/app/proguard-rules.pro:

-keep class com.mypackage.BuildConfig { *; }

(where com.mypackage is your package name)

Is there any news or workarounds on this?

I had the same issue too, fixed following some instructions provided here : https://github.com/luggit/react-native-config/issues/32

Don't forget this part https://github.com/luggit/react-native-config#extra-step-for-android on Android setup, looks like react-native link command was not adding the line automatically.

You can check these codes in MainApplication.java. If it is not exist, you can add them

import com.lugg.ReactNativeConfig.ReactNativeConfigPackage;

new ReactNativeConfigPackage();

@ozsirma where are you calling new ReactNativeConfigPackage();

@hdchan, as @ozsirma wrote in MainApplication.java:
`@Override protected List<ReactPackage> getPackages() { return Arrays.asList( ... new ReactNativeConfigPackage(), ... ); }
