I am trying to inject JavaScript for reading on specific value while loading webView.
These are the properties i used for my webView.
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setCacheMode(2);
webView.getSettings().setDomStorageEnabled(true);
webView.clearHistory();
webView.clearCache(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setUseWideViewPort(false);
webView.getSettings().setLoadWithOverviewMode(false);
webView.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");
and i am injecting javacript in my onPageFInished() method.
@Override
public void onPageFinished(final WebView view, final String url) {
webView.post(new Runnable() {
@Override
public void run() {
webView.loadUrl("javascript:window.HTMLOUT.showHTML('<head>'+document.getElementsByTagName('input')[0].value+'</head>');");
}
});
super.onPageFinished(view, url);
}
Below code is MyJavaScriptInterface.
public class MyJavaScriptInterface{
@JavascriptInterface
public void showHTML(String html_data) {
if(html_data.contains("response_code")){
Log.e(TAG, " ======> HTML Data : "+ html_data);
new MakeQueryPayment().execute();
}
}
}
Error i captured from the Logcat.

I try on Galaxy Tab 4, this code running well on this device.
WebView properties
WebView webView = new WebView(this);
setContentView(webView);
webView.clearHistory();
webView.clearCache(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setCacheMode(2);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setUseWideViewPort(false);
webView.getSettings().setLoadWithOverviewMode(false);
webView.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");
webView.loadUrl("http://stackoverflow.com/questions/34746626/uncaught-typeerror-window-htmlout-showhtml-is-not-a-function");
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return true;
}
@Override
public void onPageStarted(WebView view, String url,
Bitmap favicon) {
}
public void onPageFinished(WebView view, String url) {
view.loadUrl("javascript:window.HTMLOUT.showHTML('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>');");
}
});
JavaScript Interface
public class MyJavaScriptInterface{
@JavascriptInterface
public void showHTML(String html_data) {
Log.e("", " ======> HTML Data : "+ html_data);
}
}
For me, as it was working fine before upgrading to the latest targetSDK, I just had to add the annotation @JavascriptInterface on all my functions.
Example:
@JavascriptInterface
public void eventDragStart() {
// do somthing
}
