Android WebView kann keine Dateien herunterladen ⇐ Android

[Anonymous]

Ich arbeite mit einer HTML -Anwendung. Was ich in WebView studiert hatte, da die Website die PDF -Datei herunterladen kann.

Ausgabe ist, dass beim Laden dieser URL im Gerätebrowser die PDF -Datei automatisch heruntergeladen wird, aber in WebView kann diese Datei, die ich unten verwendet hatte, nicht herunterladen. < /p>

Code: Select all

webView.setWebViewClient(new Callback());
webView.setWebChromeClient(new webChromeClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setSavePassword(true);
webView.getSettings().setAllowFileAccess(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
webView.getSettings().setSupportMultipleWindows(false);
webView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,String contentDisposition, String mimetype,long contentLength) {
AppLog.logString(TAG+"setDownloadListener");
AppLog.logString(TAG+"url: "+url);
//Intent intent = new Intent(Intent.ACTION_VIEW);
//intent.setData(Uri.parse(url));
//startActivity(intent);
}
});
webView.loadUrl(url);

In Browser Wenn URL -Dowload -PDF -Datei in dieser URL dowloading lance & download = true) im Browser Es download, aber WebView kann dies nicht herunterladen < /p>

Ich hatte Überprüfen Sie diese URL bereits. Es funktioniert nicht, wie Sie einen Download -Manager in einem WebView verwenden, um PDF/PPT/DOC -Dateien auf SDCard
