Android webview slow

Question

My `android webviews` are slow. This is on everything from phones to `3.0+` tablets with more than adequate specs I know that webviews are supposed to be "limited" but I see web apps done with phone gap that must be using all sorts of `CSS3` and `JQuery` sorcery, they run just fine and speedy so I'm missing something, is there some kind of `myWebview.SPEEDHACK(1)` that I can use to speed things up? also, sometimes the contents of my webview just simply don't load, instead of slowly loading, it just wont load. The asset I am testing with is stored locally, no errors.

Accepted Answer

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);
```
