Trouble with RN 0.44.0
See original GitHub issueUsing:
react-native-cli: 1.2.0
react-native: 0.44.0
Followed instructions for install and usage:
$ npm install --save react-native-keep-awake
$ react-native link
Included package:
import KeepAwake from 'react-native-keep-awake';
Added component to code (in render method):
<KeepAwake />
Nothing else and I get the following:
undefined is not an object (evaluating '_reactNative.NativeModules.KCKeepAwake.activate')

I got it working by re-building the app in Android Studio and re-running
react-native run-android
I was also having an issue with this, I had it working on 1 machine when i copied it to another it was failing with the “KCKeepAwake.activate”, error; Even after i had ran I had ran react-native link, and even rnpm link.
So Inspecting the ios/build/Build/Products/Debug-iphonesimulator I noticed the compiled libKCKeepAwake.a was not being placed in this folder.
So what I needed to do is open up Xcode
not sure at what point the libKCKeepAwake.a gets generated and placed into your workspace, maybe after the the successful build.
After adding it here, reran the build, and that necessary file was now in my ios/build/Build/Products/Debug-iphonesimulator folder, and I was no longer getting the error in my simulator and device.
Hopes this works for someone else running into this issue.
