Webview not working with HTML select element

So my webview is not working with the select element. In other words when I click the select element on any page it does not show the menu.

html select element example:

<select>
    <option>test</option>
    <option>testing it</option>
    <option>bla bla bla</option>
</select>

java creating my webview:

        NestedWebView nwv = new NestedWebView(activity.getApplicationContext());
    nwv.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    registerForContextMenu(nwv);
    nwv.setWebViewClient(new webViewClient());
    nwv.setWebChromeClient(new webChromeClient(nwv));
    nwv.addJavascriptInterface(new JSInterface(), "drconsole");
    nwv.getSettings().setJavaScriptEnabled(true);
    nwv.getSettings().setLoadWithOverviewMode(true);
    nwv.getSettings().setUseWideViewPort(true);
    nwv.getSettings().setSupportZoom(true);
    nwv.getSettings().setBuiltInZoomControls(true);
    nwv.getSettings().setDisplayZoomControls(false);
    nwv.getSettings().setAllowFileAccess(true);
    nwv.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    nwv.getSettings().setSupportMultipleWindows(true);
    nwv.getSettings().setGeolocationEnabled(true);
    nwv.setDrawingCacheEnabled(true);
    nwv.getSettings().setPluginState(WebSettings.PluginState.ON);
    nwv.loadUrl(url);

    nwv.setDownloadListener(new DownloadListener(){
        @Override
        public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength){
            try{
                DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));

                String filename = new URL(url).getFile();

                request.allowScanningByMediaScanner();
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, filename.substring(filename.lastIndexOf('/')+1));
                DownloadManager dm = (DownloadManager) activity.getSystemService(DOWNLOAD_SERVICE);
                dm.enqueue(request);

                Toast toast = new Toast(activity.getApplicationContext());
                View iview = activity.getLayoutInflater().inflate(R.layout.activity_toast, (ViewGroup) activity.findViewById(R.id.toast_root));

                TextView text = (TextView) iview.findViewById(R.id.text);
                text.setText("Downloading File");
                toast.setDuration(Toast.LENGTH_SHORT);
                toast.setView(iview);
                toast.show();
            }catch(Exception e){
                e.printStackTrace();
            }
        }
    });

my build.gradle

android {
compileSdkVersion 27
buildToolsVersion '28.0.3'
defaultConfig {
    applicationId "deeproot.theanarch.org.deeproot"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

I also have almost everything possible for webviewclient and webchromeclient used. Please comment before you vote on my question.

To Fix this bug is that the webview MUST be initialized with the activity not the application context.

This line:

NestedWebView nwv = new NestedWebView(activity.getApplicationContext());

Must be:

NestedWebView nwv = new NestedWebView(activity);
