@SuppressLint("InlinedApi")
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
boolean value = true;
String extension = MimeTypeMap.getFileExtensionFromUrl(url);
if (extension != null) {
MimeTypeMap mime = MimeTypeMap.getSingleton();
String mimeType = mime.getMimeTypeFromExtension(extension);
if (mimeType != null) {
if (mimeType.toLowerCase().contains("video")
|| extension.toLowerCase().contains("mov")
|| extension.toLowerCase().contains("mp4")) {
DownloadManager mdDownloadManager = (DownloadManager) WebViewActivity.this
.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(
Uri.parse(url));
File destinationFile = new File(
Environment.getExternalStorageDirectory(),
getFileName(url));
request.setDescription("Downloading via Your app name..");
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationUri(Uri.fromFile(destinationFile));
mdDownloadManager.enqueue(request);
value = false;
}
}
if (value) {
view.loadUrl(url);
}
}
return value;
}
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
/**
* Notify the host application that a page has started loading.
*
* @param view The webview initiating the callback.
* @param url The url of the page.
*/
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
}
/**
* File name from URL
*
* @param url
* @return
*/
public String getFileName(String url) {
String filenameWithoutExtension = "";
filenameWithoutExtension = String.valueOf(System.currentTimeMillis()
+ ".mp4");
return filenameWithoutExtension;
}
}
