How can I pass a json variable to my html page in Android, using PhoneGap?
My code:
public class Activity extends DroidGap {
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
String json = readFile();
// I would pass json to menu.html
super.loadUrl("file:///android_asset/www/menu.html");
}
};
Thanks a lot.
Maybe you can use the localStorage to pass your json.
window.localstorage.setItem("Json", json);
and when you want to get this json
string json = window.localstorage.getItem("Json");
You should only be doing this if you are writing a Cordova (PhoneGap) plugin. If this is the case, you should be extending CordovaPlugin, not DroidGap. Then you will be able to return data to the JavaScript via a PluginResult object or the convenience method callbackContext.success(json) Have a look at the Plugin Development Guide, specifically the page on developing for Android.
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
super.init();
myclass = new MyClass(this, appView);
appView.addJavascriptInterface(this, "MyTeam");
super.loadUrl("file:///android_asset/www/menu.html");
}
and
public class MyClass {
private WebView mAppView;
private DroidGap mGap;
public MyClass(DroidGap gap, WebView view){
mAppView = view;
mGap = gap;
}
}
