Android Webview Hardware Rendering Weird Artifact Issue

Android WebView Hardware Rendering Weird Artifact Issue

Thanks to Delyan for solving the issue. How he told me to solve it was to add -webkit-transform: translate3d(0,0,0) to all parts that move.

KUDOS DELYAN!

Android Webview Rendering Issue

I solved issue with remove some animation css. I think this issue similar this link when using hardware hardwareaccelerated

Solving Rendering Artifacts in Frame Buffer with WebView and EditText on Android 5.0?

Ended up solving this by changing softInputMode (similar to previous WebView/Keyboard issues, but this time with a native View and EditText).

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

Android - html from android_assets in WebView, CSS not loading in ICS

Found the issue! It turns out that there is a rather big bug in the browser for ICS and presumably Honeycomb based on a test. In the logcat I get the following error: Unknown chromium error: -6. Removing the querystring solves the issue (although screws up my functionality). There is a bug report for it here if anyone else is having the same issues.

Hardware Acceleration stops working on new APIs

Tested on API 18:

Perform the check by posting a Runnable to the WebView:

WebView webView = (WebView) findViewById(R.id.webview_id);

// Shows: "Is hardware accelerated? false"
// Toast.makeText(YourActivity.this, "Is hardware accelerated? " + 
                                             // webView.isHardwareAccelerated(),
                                                 // Toast.LENGTH_LONG).show();

webView.post(new Runnable() {

    @Override
    public void run() {
        Shows: "Is hardware accelerated? true"
        Toast.makeText(YourActivity.this, "Is hardware accelerated? " + 
                                              webView.isHardwareAccelerated(),
                                                  Toast.LENGTH_LONG).show();

        if (webView.isHardwareAccelerated()) {
            // isAccelerated();
        } else {
            // isNotAccelerated();
        }
    }
});

From resource page on Hardware Acceleration:

Hardware acceleration is enabled by default if your Target API level
is >=14, but can also be explicitly enabled.

If the image you are displaying is still pixelated, try setting:

webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

and see if pixelation of the image gets better.

Consider reading the resource page on Hardware Acceleration.
