钴应用支持Android触摸屏设备，需要在代码中添加以下代码片段：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    WebView.enableSlowWholeDocumentDraw();
}

webView.setWebChromeClient(new WebChromeClient() {
    @Override
    public void onPermissionRequest(final PermissionRequest request) {
        request.grant(request.getResources());
    }
});

webView.setWebViewClient(new WebViewClient() {
    @Override
    public boolean shouldOverrideUrlLoading(final WebView view, final String url) {
        view.loadUrl(url);
        return true;
    }
});

WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webSettings.setSupportZoom(false);
webSettings.setAllowFileAccess(false);
webSettings.setAllowContentAccess(false);
webSettings.setAllowFileAccessFromFileURLs(false);
webSettings.setAllowUniversalAccessFromFileURLs(false);
webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);

ReLinker.loadLibrary(context, "native-lib");

webView.loadUrl("file:///android_asset/index.html");

通过在Android应用程序中添加上述代码，就可以使得钴应用支持Android触摸屏设备。
