Surface - dequeueBuffer failed (Unknown error 2147483646)

Question

I tried for 3 days an Android application that uses webview to download my website containing thousands of images. The application starts well, but after scrolling through a couple of hundred images the webview freezes (doesn’t force-close) logcat (check it on pastebin) shows

 E/Surface dequeueBuffer failed (Unknown error 2147483646) 

What I tried:

• To limit the number of images for each action, when the user views 100 images, start another action.
• Clear web cache cache onCreation, onPause, onStop, etc. clearCache(true);
• Set the web cache cache to false setAppCacheEnabled(false);
• Kill activity A after opening operation B and vice versa
• Set webView.setLayerType() to NONE, SOFTWARE and HARDWARE
• Declare "android:largeHeap="true" and android:hardwareAccelerated="true" in the manifest.
• Place the web view inside the placeholder, delete it before finish();

---

 webViewPlaceholder.removeView(myWebView); myWebView.removeAllViews(); myWebView.destroy(); 

It seems that android stores the webview in memory, and clearing the cache has no effect.
When I close the application and open it again, an error appears immediately, so it seems that even closing the application does not free up the memory that it uses.
I honestly don’t see a way to fix this, I read a lot of answers on SO to web browsing problems, but I still could not fix this problem. I would appreciate the light here!

Answer 1

for KitKat 4.4.3 or later, set the hardware acceleration to false:

 webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
