如何从一个Android Activity打开两个react-native Activity

Question

从MainActivity，这是一个普通的android java活动，我想使用2个按钮打开2个react-native活动（ReactActivity或Activity）。我知道如何从Android活动中调用javascript代码，如下所示：

public class MyReactActivity extends Activity implements DefaultHardwareBackBtnHandler {
private ReactRootView mReactRootView;
private ReactInstanceManager mReactInstanceManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mReactRootView = new ReactRootView(this);
    mReactInstanceManager = ReactInstanceManager.builder()
            .setApplication(getApplication())
            .setCurrentActivity(this)
            .setBundleAssetName("index.android.bundle")
            .setJSMainModulePath("index")
            .addPackage(new MainReactPackage())
            .setUseDeveloperSupport(BuildConfig.DEBUG)
            .setInitialLifecycleState(LifecycleState.RESUMED)
            .build();
    // The string here (e.g. "MyReactNativeApp") has to match
    // the string in AppRegistry.registerComponent() in index.js
    mReactRootView.startReactApplication(mReactInstanceManager, "MyReactNativeApp", null);

    setContentView(mReactRootView);
}

@Override
public void invokeDefaultOnBackPressed() {
    super.onBackPressed();
}
}

现在我应该使用.setJSMainModulePath（“ login”）之类的东西代替.setJSMainModulePath（“ index”）吗？如果是这样，那么除了“索引”模块（例如“登录”模块）之外，如何创建另一个模块？
