Question

I wan to call a javascript function from an android activity but it doesn\'t seem to work. I have used the android webview function webview.loadUrl(\"javascript:function()\"

Answer 1

Try:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    webview = (WebView)findViewById(R.id.webView1);
    webview.getSettings().setJavaScriptEnabled(true);
    webview.loadUrl("file:///android_asset/index.html");
    webview.loadUrl("javascript:change("+String.valueOf(i)+")");

}
