一，繼承 ReactContextBaseJavaModule 實現如下方法  自定義方法用 @ReactMethod註釋
/**
            * 日誌列印module
    * Created by ybj on 2016/2/26.
            */
public class ReactLogModule extends ReactContextBaseJavaModule {
        private static final String MODULE_NAME="Log";
    private static final String TAG_KEY = "TAG"
 
;
    private static final String TAG_VALUE = "LogModule";
    public ReactLogModule(ReactApplicationContext reactContext) {
        super(reactContext);
}

    @Override
public String getName() {
        return MODULE_NAME;
}
    @ReactMethod
public  void  d(String tag,String message){
        Log.d
 
(tag,message);
/* WritableMap params = Arguments.createMap();
        params.putString("TAG",tag);
        params.putString("MSG",message);
        getReactApplicationContext()
                .getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
                .emit("logInConsole", params);//對應的javascript層的事件名為logInConsole，註冊該事件即可進行回撥*/
 
}

    @Override
public Map<String, Object> getConstants() {
        final Map<String,Object> constants= MapBuilder.newHashMap();
constants.put(TAG_KEY,TAG_VALUE);
        return constants;
}
}

二，繼承ReactPackage，實現如下

/**
 * 日誌列印 需要列印日誌註冊this
 * Created by ybj on 2016/2/26.
 */
public class ReactLogPackage implements ReactPackage {


    @Override
public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) {
        List<NativeModule> modules=new ArrayList<NativeModule>();
ReactLogModule reactLogModule=new ReactLogModule(reactContext);
modules.add(reactLogModule);
        return modules;
}

    @Override
public List<Class<? extends JavaScriptModule>> createJSModules() {
        return Collections.emptyList();
}

    @Override
public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) {
        return Collections.emptyList();
}
}

三 新增package

mReactInstanceManager = ReactInstanceManager.builder()
        .setApplication(((Activity) mContext).getApplication())

        .setJSBundleFile(bundleFile)
                //  .setJSMainModuleName("test")
.setNativeModuleCallExceptionHandler(new NativeModuleCallExceptionHandler() {
            @Override
public void handleException(Exception e) {
            }
        }).addPackage(new MainReactPackage())
        .addPackage(new ReactLogPackage())
       

        .setUseDeveloperSupport(false)
        .setInitialLifecycleState(LifecycleState.RESUMED)
        .build();
mReactRootView.startReactApplication(mReactInstanceManager, "OperationActivity", null);
