Not working with 0.56.0

  > The SDK Build Tools revision (23.0.1) is too low for project

PR 248 may solve this problem, but I have not tested it.

[craigcoles]

@pedro I have tested #248 on a fork, simpleweb/react-native-config.

I can confirm that I have it working on RN 0.56.0.

[XenorPLxx]

#270 is also resolving the issue and provides pattern used in other RN projects with native code as react-native-camera and react-native-fabric

[taranda]

#248 does not work on a new React Native project. I reviewed and recommended some changes.

[craigcoles]

@taranda I was running version 0.55.4 and then upgraded to 0.56.0 and everything was fine and dandy, even before the upgrade. I think the problem is solely with the version of Gradle. I am using react-native-firebase and that required me to upgrade to at least v4.4.

[taranda]

@craigcoles That is a valid point.

I will say that not everyone will upgrade to gradle 4.4. React Native 0.56 "ships" with gradle 3. It would be nice if react-native-config worked "out of the box" with React Native 0.56 and not require the user to update their gradle. Especially if there is no compelling reason to use gradle 4 other than the googl() function. The review I made to PR #248 definitely works "out of the box". I suspect PR #270 does as well.

A workaround while this issue is not fixed is to override the version in android/build.gradle with the following code at the end of the file

subprojects { subproject ->
    afterEvaluate {
        if ((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
            android {
                compileSdkVersion rootProject.ext.compileSdkVersion
                buildToolsVersion rootProject.ext.buildToolsVersion
            }
        }
    }
}

No change is required for the plugin to work after this. This unfortunately will hide other library buildTools version mismatch.

@alwex solution is the best as far though pushing all subprojects this way does not seem to be the perfect idea.

I assume that this repo is not getting maintained anymore.

I was able to run version 0.8.1 on react-native version 0.56. version 11.5 of react-native-config was returning an empty object when running on RN version 0.56.

[amed]

@drewandre make sure you did link the library.

[tizzyapunkt]

I have the same issue regarding the empty object.
Tried several suggestions including the ones of @drewandre and @alwex.
Any other ideas?

[amed]

@tizzyapunkt what exactly is your situation? Does the build fail or Config returns empty object?

[tizzyapunkt]

@amed The config object was empty.
The linking command did not work as expected. I checked out the android example and saw how it has to be done in the MainApplication.java.

import com.facebook.react.ReactApplication;
...
import com.lugg.ReactNativeConfig.ReactNativeConfigPackage;  // <--- added this manually
...

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
            new ReactNativeConfigPackage() // <--- added this manually
      );
    }
....

[amed]

There is an extra step for android:
in android/app/build.gradle file add the following:

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

check https://github.com/luggit/react-native-config#extra-step-for-android

This may leads to the current issue topic, which is an issue building for Android.

@amed
I did the extra step you mentioned as it is documented in the readme.
But as the automatic linking seems to be broken, the MainApplication.java needs to be updated manually.

[drewandre]

@amed No, I actually didn't link the library which was my problem. I thought you meant just run react-native link, but that is not functioning properly on RN 0.56. Running react-native link followed by manually linking libReactNativeConfig.a under Link Binary With Libraries like you suggested did the trick for me. All on react-native-config version 0.8.1. Thank you!
