reactnative 安卓native module canO

@Override

protected ListgetPackages() {

return Arrays.asList(

new MainReactPackage(),

        new PreferencePackage(),

        new PickerViewPackage(),

        new OrientationPackage(),

        new RNFSPackage(),

        new RNReactNativeDocViewerPackage(),

        new RNDeviceInfo(),

        new JsReactPackage()

);

一般是MainApplication.java 重复引用导致
