Weird exception: Cannot cast String to Boolean when using getBoolean

Question

I\'m getting a very weird error. I have 2 activities. On both I\'m getting the SharedPreferences using MODE_PRIVATE (if it matters) by sp = g

Answer 1

The exception occurs in this Android method:

public boolean getBoolean(String key, boolean defValue) {
    synchronized (this) {
        awaitLoadedLocked();
        Boolean v = (Boolean)mMap.get(key); // On this line
        return v != null ? v : defValue;
    }
}

The only sense I can make of this error is that your are reusing the key IntroActivity.SHOW_INTRO for a String somewhere else in your code.
