Transferring Int Variable Between Activities Android

I am making a quiz game. However, I need to add a score variable that can be modified. The way the game works is it uses a few different activities. How can I transmit this score a

Solution 1:

Here's an example of passing an integer from one activity to another activity.

Start ActivityA and pass it the int like this:

Intent theIntent = newIntent(this, ActivityA.class);
theIntent.putExtra("somename", intVariable);  
startActivity(theIntent);

Get the integer from within ActivityA like this:

int i = getIntent().getIntExtra("somename");

Solution 2:

trying this do not work in my activity onCreate-method. Method do need a default value as second parameter.

intid = getIntent().getIntExtra(DetailClick.ID_NAME,-1);

Hope this helps!
