Android webview slow

It depends on the web application being loaded. Try some of the approaches below:

Set higher render priority (deprecated from API 18+):

webview.getSettings().setRenderPriority(RenderPriority.HIGH);

Enable/disable hardware acceleration:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {    // chromium, enable hardware acceleration    webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);} else {    // older android version, disable hardware acceleration    webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);}

Disable the cache (if you have problems with your content):

webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

Adding this android:hardwareAccelerated="true" in the manifest was the only thing that significantly improved the performance for me

The solution for us was the opposite. We disabled hardware acceleration on the WebView only (rather than on the entire app in the manifest) by using this code:

if (Build.VERSION.SDK_INT >= 11){    webview.setLayerType(View.LAYER_TYPE_SOFTWARE, null);}

CSS3 animations are smoother now. We are using Android 4.0.
