Dopo lunghe ricerche, ho trovato questa cosa funzionante. Vedere il codice seguente:
Test.java
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
public class Test extends Activity {
HTML5WebView mWebView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebView = new HTML5WebView(this);
if (savedInstanceState != null) {
mWebView.restoreState(savedInstanceState);
} else {
mWebView.loadUrl("http://192.168.1.18/xxxxxxxxxxxxxxxx/");
}
setContentView(mWebView.getLayout());
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mWebView.saveState(outState);
}
@Override
public void onStop() {
super.onStop();
mWebView.stopLoading();
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
if (mWebView.inCustomView()) {
mWebView.hideCustomView();
// mWebView.goBack();
//mWebView.goBack();
return true;
}
}
return super.onKeyDown(keyCode, event);
}
}
