How to get return value from javascript in WebView of Android?
Same as Keith but shorter answer
webView.addJavascriptInterface(this, "android");webView.loadUrl("javascript:android.onData(functionThatReturnsSomething)");And implement the function
@JavascriptInterfacepublic void onData(String value) { //.. do something with the data}Don't forget to remove the onData from proguard list (if you have enabled proguard)
Here's a hack on how you can accomplish it:
Add this Client to your WebView:
final class MyWebChromeClient extends WebChromeClient { @Override public boolean onJsAlert(WebView view, String url, String message, JsResult result) { Log.d("LogTag", message); result.confirm(); return true; } }Now in your javascript call do:
webView.loadUrl("javascript:alert(functionThatReturnsSomething)");Now in the onJsAlert call "message" will contain the returned value.
