Manually

iOS

1. In the XCode's "Project navigator", right click on your project's Libraries folder ➜ Add Files to <...>
2. Go to node_modules ➜ react-native-idle-timer ➜ ios ➜ select RNIdleTimer.xcodeproj
3. Add libRNIdleTimer.a to Build Phases -> Link Binary With Libraries

Android

1. in android/settings.gradle

...
include ':react-native-idle-timer'
project(':react-native-idle-timer').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-idle-timer/android')

2. in android/app/build.gradle add:

dependencies {
  ...
  compile project(':react-native-idle-timer')
}

3. and finally, in android/src/main/java/com/{YOUR_APP_NAME}/MainActivity.java add:

//...
import com.marcshilling.idletimer.IdleTimerPackage; // <--- This!

//...
@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
    new MainReactPackage(),
    new IdleTimerPackage() // <---- and This!
  );
}

Usage

In your React Native javascript code, bring in the native module:

import IdleTimerManager from 'react-native-idle-timer';

To disable the idle timer while a certain component is mounted:

Class component

componentWillMount() {
  IdleTimerManager.setIdleTimerDisabled(true);
}

componentWillUnmount() {
  IdleTimerManager.setIdleTimerDisabled(false);
}

Function component

useEffect(() => {
  IdleTimerManager.setIdleTimerDisabled(true);

  return () => IdleTimerManager.setIdleTimerDisabled(false);
}, [])

If you have multiple components that are responsible for interacting with the idle timer, you can pass a tag as the second parameter:

useEffect(() => {
  IdleTimerManager.setIdleTimerDisabled(true, "video");

  return () => IdleTimerManager.setIdleTimerDisabled(false, "video");
}, [])

If you need to interact from the native Android or iOS side:

Android

IdleTimerManager.activate(activity, "video");
IdleTimerManager.deactivate(activity, "video");

iOS

[IdleTimerManager activate:@"video"];
[IdleTimerManager deactivate:@"video"];
