Let Android WebView support the uploading of files inside HTML

By default, Android WebView is not supported <input type=file>, click No response, if you want to click Upload, pop-up Select file, Picture window, then you need to customize a webchromeclient

 Public classMychromeclient extends Webchromeclient { PublicValuecallback<uri>uploadmsg;  PublicValuecallback<uri[]>UPLOADMSG2; PrivateActivity activity;  Public StaticFinalintFilechooser_resultcode =5173;  Public StaticString Mcamerafilepath =""; @SuppressWarnings ("Deprecation")     Publicmychromeclient (Activity Cordova) { This.

Then specify webview to use this client

New Mychromeclient (this));
