how to pass value data between classes/activity in Android?

Question

For example i have activity1, activity2, activity3 and lastly valueAllActivity? how do I pass the data from activity1, activity2, activity3 to --> valueAllActivity?

Answer 1

I used a method in an activity to call another activity. It starts a game with two variables (resume and number of players).

private void MethodToCallAnotherActivity(int resume, int players) {     
    Intent intent = new Intent(CurrentActivity.this, NextActivity.class);
    intent.putExtra(NextActivity.RESUME, resume);
    intent.putExtra(NextActivity.PLAYERS, players);
    startActivity(intent);
}

in the 'onCreate' of the NextActivity, I used

int resume = getIntent().getIntExtra(Game.RESUME, 1);

to read the variable I wanted.

Good luck!
