I'm attempting to get a HTML5 localStorage example working within an Android WebView (Webkit, ChromeClient). However I'm having no luck. Everything works from the phones browsers just not from the WebView.
Activity:
public class BrowserActivity extends Activity {
@Override
public final void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView browser = (WebView) findViewById(R.id.webView);
browser.setHapticFeedbackEnabled(true);
browser.getSettings().setJavaScriptEnabled(true);
browser.getSettings().setSavePassword(false);
browser.getSettings().setDatabaseEnabled(true);
browser.getSettings().setDomStorageEnabled(true);
browser.getSettings().setDatabasePath("/data/data/" + browser.getContext().getPackageName() + "/databases/");
browser.loadUrl("http://my.app.com:10099");
}
}
Manifiest:
