Enabling HTML5 AppCache in Android Webview programatically.

enableHTML5AppCache.java

private void enableHTML5AppCache() {
		
	      webView.getSettings().setDomStorageEnabled(true);
	       
	      // Set cache size to 8 mb by default. should be more than enough
	      webView.getSettings().setAppCacheMaxSize(1024*1024*8);
	       
	      // This next one is crazy. It's the DEFAULT location for your app's cache
	      // But it didn't work for me without this line
	      webView.getSettings().setAppCachePath("/data/data/"+ getPackageName() +"/cache");
	      webView.getSettings().setAllowFileAccess(true);
	      webView.getSettings().setAppCacheEnabled(true);
	      
	      webView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
	}

You have to check for internet connectivity before telling to load from cache

thanks!!! a lot!

Did anybody found that the Application Cache path is not in the path which setted in setAppCachePath funciton("/data/data/"+ getPackageName() +"/cache")，but it was in data/data/packagename/app_webview/Application Cache on Kitkat？

it works， thanks

appcache method will deprecated, you can look at this lib https://github.com/yale8848/CacheWebView , hope help you

Thanks, It solved my issue. I was trying to show angular component inside webview but It was not showing, after I get to know that Angular requires html5 support, adding this code help me to solve issue

thank you brooooooo. thats fucking awesome

It's good, but some apps or android versions can change this path. Then, use "getFilesDir()", instead of "data/data".

webView.getSettings().setAppCachePath(getFilesDir() + getPackageName() +"/cache");
