Question

I have Main class and it contains function isSyncAllowed. I start another service. How to call function isSyncAllowed from this service?
It says:

Cannot make a static reference to the
non-static method
isSyncAllowed(Boolean) from the type
Main

If I change type of that function to static and pass context, I come to the problem that startManagingCursor can not be static.

How can I fix it?

Upd. Here is the code of SyncService:

public class SyncService extends BroadcastReceiver {
...
    public void onReceive(Context context, Intent intent) {
    ...
    Boolean isDownloadAllowed = Kinobaza.isSyncAllowed(true);
    }

and here is the code of Main:

public class Kinobaza extends ListActivity {
    ...
    public static Boolean isSyncAllowed(Boolean showToasts) {
        ...
        Cursor notesCursor = mDbHelper.fetchAllNotes();
        startManagingCursor(notesCursor); // here is the error
    }
}

You are probably doing Main.isSyncAllowed(...) instead of main.isSyncAllowed(...), where main is an object of class Main.

If you are inside an instance method of Main, then you can simply do isSyncAllowed(...).

Edit – now that I see your code, you should probably pass isSyncAllowed via the Intent you give to the service. When you start the service:

Intent intent = /* however you were constructing your intent */
boolean syncAllowed = /* calculate syncAllowed by calling your existing method */
intent.putExtra("syncAllowed", syncAllowed);
    ...

and then in your service you can retrieve it:

boolean syncAllowed = getIntent().getBooleanExtra("syncAllowed", true);

Your service shouldn’t need to call instance methods on your activities.
