Cant play .swf(flash files) files from internal storage in android webview on jellybean installed devices (for eg:-nexus7) but i can play .swf(flash files) on android honeycomb devices... Also i figured this out as jellybean onwards android stopped supporting flash files plugin and even adobe stopped developing for the same in android.
Here is some code snippets that i tried with no results----
wv = (WebView) findViewById(R.id.webView1);
String url =Environment.getExternalStorageDirectory()+"/FolderName/Filename.swf";
wv.setWebChromeClient(new WebChromeClient());//also tried WebViewClient
wv.getSettings().setJavaScriptEnabled(true);
wv.getSettings().setPluginState(PluginState.ON);
wv.getSettings().setAllowFileAccess(true);
wv.getSettings().setUseWideViewPort(true);
wv.loadUrl(url);
only a small icon is shown at the centre of webview. [Note- i have even tried to load using html file but nothing worked]
