Package Exports

react-native-keypair-lib

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-keypair-lib) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage (Android)

Make alterations to the following files:

android/settings.gradle

...
include ':react-native-keypair-lib'
project(':react-native-keypair-lib').projectDir = new File(settingsDir, '../node_modules/react-native-keypair-lib/android')

android/app/build.gradle

...
dependencies {
    ...
    implementation project(':react-native-keypair-lib')
}

register module (in MainActivity.java)
- For react-native below 0.19.0 (use cat ./node_modules/react-native/package.json | grep version)

import com.reactlibrary.ReactNativeKeypairLibPackage;  // <--- import

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {

  ......

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mReactRootView = new ReactRootView(this);

    mReactInstanceManager = ReactInstanceManager.builder()
      .setApplication(getApplication())
      .setBundleAssetName("index.android.bundle")
      .setJSMainModuleName("index.android")
      .addPackage(new MainReactPackage())
      .addPackage(new ReactNativeKeypairLibPackage())      // <------- add package
      .setUseDeveloperSupport(BuildConfig.DEBUG)
      .setInitialLifecycleState(LifecycleState.RESUMED)
      .build();

    mReactRootView.startReactApplication(mReactInstanceManager, "ExampleRN", null);

    setContentView(mReactRootView);
  }

  ......

}

For react-native 0.19.0 and higher

import com.reactlibrary.ReactNativeKeypairLibPackage; // <------- add package

public class MainActivity extends ReactActivity {
   // ...
    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        new MainReactPackage(), // <---- add comma
        new ReactNativeKeypairLibPackage() // <---------- add package
      );
    }

For react-native 0.29.0 and higher ( in MainApplication.java )

import com.reactlibrary.ReactNativeKeypairLibPackage; // <------- add package

public class MainApplication extends Application implements ReactApplication {
   // ...
    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        new MainReactPackage(), // <---- add comma
        new ReactNativeKeypairLibPackage() // <---------- add package
      );
    }
