I need to pass a long (_id) with an intent from Activity A to Activity B, using this code:

Intent vip0= new Intent(this, PageSinglePlayerGuess.class);
vip0.putExtra("resid", (long) 1);
startActivity(vip0);

and getting it in Activity B with this method (called in onCreate()):

public long getResId() {
    Intent i= getIntent();
    resid= i.getLongExtra("resid", 1);
    Log.d("D", "Risorsa: " + resid);
    return resid;
}

resid in ActB is a long.
I get this error: 

    06-06 11:10:47.138: W/Bundle(538): Key resid expected Long but value was a java.lang.Integer.  The default value 1 was returned.

    According to the log the problem seems to be in following:

    resid= i.getLongExtra("resid", 1);

    so change it to:

    resid= i.getLongExtra("resid", 1L);

    BTW: the getLongExtra implementation looks like this:

    public long getLongExtra(String name, long defaultValue) {
   return mExtras == null ? defaultValue : mExtras.getLong(name, defaultValue);
}

    So that’s why see that it fails at line:

    at android.os.Bundle.getLong(Bundle.java:966)
