I tried to pass a string parameter to the web app javascript code. It's failed while passing a variable with the string value. But it works when we hardcode the data. Please let me know what's wrong with this. Working hardcoded code:

String password, boolean isReplace, Message resumeMsg). void, openFileChooser(ValueCallback uploadFile, String acceptType, String captureType).

get();  ValueCallback; //導入方法依賴的package包/類 public static void evaluateJavascript(js,null); final ValueCallback proxyCallback = callback ;  set this to any string that won't occur in your keys 'msg' => 'walkArray() was called without $keyCallback or $valueCallback as existing function names. see  26 Oct 2020 innerHTML+''); })();", new ValueCallback() { @Override public void onReceiveValue(String html) { } });. I am getting this html string  23 Jul 2012 new ValueCallback() { @Override public void onReceiveValue(String s) { // Do what you want with the return value } });. 25 Aug 2017 override abstract method evaluateJavascript(String,ValueCallback) in CordovaWebViewEngine public class XWalkWebViewEngine  Use an anonymous class webView.evalueateJavascript("a", object : ValueCallback() { override fun onReceiveValue(value: String) { println( value) } 12 Mar 2020 private valuecallbackuploadmessageabovel;; private final static int if ( intent!=null) {; string datastring=intent.getdatastring ();; clipdata  6 Jan 2016 openFileChooser(ValueCallback uploadMsg, String acceptType) works on Android 3.0 (API level 11) up to Android 4.0 (API level 15)  2018年5月27日 public void openFileChooser(ValueCallback valueCallback, String acceptType, String capture) { uploadMessage = valueCallback;  31 Mar 2019 evaluateJavascript(string, new ValueCallback() { @Override public void onReceiveValue(String value) { //Callback after invocation can  2017年1月16日 public void openFileChooser(ValueCallback valueCallback, String acceptType, String capture) { uploadMessage = valueCallback;  27 Feb 2018 strong support for the proposal. The core idea is that Anything can be made into a valid identifier by wrapping it in backticks In string interpola… 9 May 2019 You can imagine that in a real scenario that the string would come from a real source instead of being hardcoded.

By the way, you can see below code contain "web" is my variable name, I have retrieved and stored my Webview from activity_main.xml.you need to replace that variable "web" with your variable name.

Hi, I was also searching solution for the same problem. After a long search I got a blog that has complete webview app development series videos, pictures, text tutorials guidelines and codes.

After that, you need to write code for showing "file chooser". Just copy the below code and paste it into your WebChromeClient function.

Please let me know what's wrong with this.

webView1.evaluateJavascript("return \"test\";", new ValueCallback() { @Override public void onReceiveValue(String s) { Log.d("LogName", s); // Log is written, but s is always null } }); Loadurl (string url, map < string, string > additionalhttpheaders): load the specified url and carry the http header data. Evaluate JavaScript (string script, valuecallback ResultCallback): after API 19, you can use this method to go to Js. stopLoading(): stops the current WebView load. In this method, using the ValueCallback object we saved before and calling the onReceiveValue method, H5 can receive the address information we passed to it.
