manual link process

Edit android/settings.gradle:

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

Edit android/app/build.gradle:

dependencies {
  compile fileTree(dir: "libs", include: ["*.jar"])
  compile "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
  compile "com.facebook.react:react-native:+"  // From node_modules
+ compile project(':react-native-immersive')
}

Edit android/app/src/main/java/.../MainApplication.java:

+ import com.rnimmersive.RNImmersivePackage;

...

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

Basic Usage

import { Immersive } from 'react-native-immersive'

// methods (Android only, will throw Error on iOS in __DEV__ mode)
Immersive.on()
Immersive.setImmersive(true)

Immersive.off()
Immersive.setImmersive(false)

Restore Immersive State

The Immersive State do not last forever (SYSTEM_UI_FLAG_IMMERSIVE_STICKY is not sticky enough).
The Immersive State will get reset when:

  • coming back to active AppState
  • after Keyboard opening
  • after Alert opening
  • after Modal opening

To restore the Immersive State, add an additional listener.

// listener for Immersive State recover
const restoreImmersive = () => {
  __DEV__ && console.warn('Immersive State Changed!')
  Immersive.on()
}
Immersive.addImmersiveListener(restoreImmersive)
Immersive.removeImmersiveListener(restoreImmersive)

The Native Module itself will cover some basic Immersive State change (but not something like Modal + Alert).
To get all Immersive State change, edit android/app/src/main/java/.../MainActivity.java:

+ import com.rnimmersive.RNImmersiveModule;
...

public class MainActivity extends ReactActivity {
  ...
+ @Override
+ public void onWindowFocusChanged(boolean hasFocus) {
+   super.onWindowFocusChanged(hasFocus);
+
+   if (hasFocus && RNImmersiveModule.getInstance() != null) {
+     RNImmersiveModule.getInstance().emitImmersiveStateChangeEvent();
+   }
+ }
}

Unified Compile Version

solution from SudoPlz react-native-keychain

When compile ReactNative android,
different package may set different compileSdkVersion and buildToolsVersion.

To force all the submodules to use the specified compileSdkVersion and buildToolsVersion,
add the following code to android/build.gradle:

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 27
                buildToolsVersion "27.0.3"
            }
        }
    }
}
