Question

I am new to Android SDK (not java) and I had a question or two about options menus. I look around for several tutorials, including the developer.android one. My problem is the naming of files. The menu works fine when in my res/menu folder the menu xml document is titled menu.xml. If I try to call in mainMenu.xml I get a
mainMenu cannot be resolved or is not a field
error.
Here is the code in my main activity,

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.mainMenu, menu);
    return true;
}

The “mainMenu” in R.menu.mainMenu in the above code is underlined in red (error)
So my question is can I name my menu file anything I want? This way seems to restrict me to one options menu per project which cannot be correct (unless I am missing something : )

Answer 1

You can definitely have multiple options menus: there may be a lower case restriction though. Use underscores and you should be all set?

EDIT: yep, this error message occurs when you try and build:

[2011-05-20 12:09:40 - BlAH BLAH BLAH] res\menu\newMenu.xml: Invalid file name: must contain only [a-z0-9_.]

So there is a lower case restriction. Never knew that.
