Getting Around X-frame-options Deny In An Android Webview

I am attempting to implement a technique similar to the one describe in this question. I have an android application (Ionic built on top of Cordova) that runs in a webview. Basica

Solution 1:

I was able to solve my problem by using the OkHttpClient found here: http://square.github.io/okhttp/ instead of the java URLConnection

  // Handle API until level 21
  @TargetApi(Build.VERSION_CODES.LOLLIPOP)
  @Override
      public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
        try {
          WebResourceResponse cordovaResponse = super.shouldInterceptRequest(view, request);
          if(cordovaResponse != null) {
            return cordovaResponse;
          }
          String url = request.getUrl().toString();
          OkHttpClient httpClient = new OkHttpClient();
          Request okRequest = new Request.Builder()
            .url(url)
            .build();
          Response response = httpClient.newCall(okRequest).execute();
          Response modifiedResponse = response.newBuilder()
            .removeHeader("x-frame-options")
            .removeHeader("frame-options")
            .build();
          return new WebResourceResponse("text/html",
            modifiedResponse.header("content-encoding", "utf-8"),
            modifiedResponse.body().byteStream()
          );

    } catch(MalformedURLException e) {
      e.printStackTrace();
      return null;
    }
    catch (IOException e) {
      e.printStackTrace();
      return null;
    }
  }
