Javascript Android Webview未加载

我正在尝试制作一个可以打开

webview

的应用程序，这个url可以打开自己的

css

和

js

文件，

css

可以正常打开，但是

js

根本无法打开。 我尝试了一些功能，比如

OnPageLoad

，

webclient

，但仍然没有得到积极的结果，我正在运行

android 4.1.2

，但是当在

android 4.4.2

中运行相同的项目时，它工作了。。js文件加载，应用程序运行正常。。我能做些什么使它也在

4.1.2

中工作

我的代码

    public class Activity2 extends Activity {

WebView webView;
Context context;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    webView = new WebView(this);
setContentView(webView);
context = this;
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setDomStorageEnabled(true);


try {
    InputStream stream = this.getAssets().open("coresAPP.html");
    int streamSize = stream.available();
    byte[] buffer = new byte[streamSize];
    stream.read(buffer);
    stream.close();
    String html = new String(buffer);
    webView.loadDataWithBaseURL("file:///android_asset/", html, "text/html", "UTF-8", null);

}
catch (IOException e) {
e.printStackTrace();

     }
  }

}
