I am creating a widget that needs to make a network connection to update its information.
I'm pretty much using Android Studio boilerplate template for Widgets, and its onUpdate method comes with this:
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// There may be multiple widgets active, so update all of them
final int N = appWidgetIds.length;
for (int i = 0; i < N; i++) {
updateAppWidget(context, appWidgetManager, appWidgetIds[i]);
}
}
where updateAppWidget is a static function.
The problem is that I'm making use of AsyncTask to make a network connection, retrieve some data and update the widget's its values:
private class APIQuery extends AsyncTask<Connection, Integer, String> {
@Override
protected String doInBackground(Connection... params) {
// ...
}
}
The problem is inside updateAppWidget because if I try to instantiate APIQuery from within updateAppWidget, Android Studio says that I cannot call a non-static method from a static method.
Based on this answer:
calling non-static method in static method in Java
The only way to call a non-static method is by instantiating the class, but if I instantiate APIQuery, then Android says that I have to either make updateAppWidget non-static, or APIQuery static.
What is the right way to approach this situation? I'm new to Java and Android development, and learning as I go.
