Dears I have Webview app and I can't open any WhatsApp links or telephone I use the following code
@Override
public void menuItemClicked(Action action, MenuItem item) {
if (WebToAppWebClient.urlShouldOpenExternally(action.url)){
//Load url outside WebView
try {
startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(action.url)));
} catch(ActivityNotFoundException e) {
if (action.url.startsWith("intent://") || (action.url.startsWith("whatsapp:")
|| (action.url.startsWith("tel:")))){
startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(action.url.replace("intent://", "http://"))));
new Intent(Intent.ACTION_VIEW, Uri.parse(action.url.replace("whatsapp:", "http://")));
new Intent(Intent.ACTION_VIEW, Uri.parse(action.url.replace("tel:", "http://")));
} else {
Toast.makeText(this, getResources().getString(R.string.no_app_message), Toast.LENGTH_LONG).show();
}
