我正在尝试从我的sd加载pdf到webview。 我知道在webview中直接加载pdf是不可能的。所以我有一个html文件，它呈现文件并加载pdf。
来自 http://www.worldwidewhat.net/2011/08/render-pdf-files-with-html5/ 的 样本
Android代码： 来自logcat的Erros： 但是 - ＆gt;
如果我将此文件存储在云中并按上面的方式加载它，它将正常工作。
任何人都知道为什么这不会在本地加载？
谢谢你们。 P.S我知道网上有很多这样的问题。我环顾四周，找不到解决办法。 final WebView webView = (WebView) findViewById(R.id.magazineWebView);
final ProgressBar spinner = (ProgressBar) findViewById(R.id.magazineSpinner);
webView.setBackgroundColor(0xFFFFFFFF);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setSaveFormData(true);
webView.getSettings().setBuiltInZoomControls(mgznCanZoom);
webView.getSettings().setDisplayZoomControls(false);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setPluginState(WebSettings.PluginState.ON);
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
spinner.setVisibility(View.GONE);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
String webPath = "http://mysite/demo/pdf-js/index.htm"; //WORKS
String file_name2 = "pdf-js/index.htm"; //LOAD HTML BUT NOT PDF
String file_uri = MAGAZINE_FOLDER + file_name2;
String sdPath = Uri.parse("file://"
+ Environment.getExternalStorageDirectory()
+ file_uri).toString();
webView.loadUrl(sdPath); //webPath
