javascript界面​​在5.0以下不起作用

Question

1. 当我的webview扩展时，我使用下面的代码来避免空格 它在5.0
中运行良好

我添加了suppresslint @SuppressLint（{＆＃34; SetJavaScriptEnabled＆＃34;，＆＃34; JavascriptInterface＆＃34;}）以避免错误

但Android 4.2,4.3设备仍有空白区域

有人建议我解决这个问题。

web_content_url.setWebViewClient(new WebViewClient() {
                public boolean shouldOverrideUrlLoading(WebView view, String url) {
                    Log.i(TAG, "Processing webview url click...");
                    pbar2.setVisibility(view.VISIBLE);
                    view.loadUrl(s[1]);
                    return true;
                }

                public void onPageFinished(WebView view, String url) {
                    Log.i(TAG, "Finished loading URL: " + url);
                    pbar2.setVisibility(view.GONE);
                    view.loadUrl("javascript:MyApp.resize(document.body.getBoundingClientRect().height)");
                    super.onPageFinished(view, url);

                }

                public void onReceivedError(WebView view, int errorCode,
                        String description, String failingUrl) {
                    Log.e(TAG, "Error: " + description);
                    pbar2.setVisibility(view.VISIBLE);
                }

            });
            web_content_url.addJavascriptInterface(this, "MyApp");
