Passing data througth activities

Question

I would like to pass data from an activity to an other using intent but it won't work. I think I did something wrong in my code.

        if (condition) {
            Hero = arrayP.get(0).name;
            Intent i = new Intent(Activity2.this, Activity3.class);
            i.putExtra("name");
            startActivity(i);

        }

@Fra,

You code is bit incorrect. You can pass data from one activity to another activity by using

Intent i = new Intent(Activity2.this, Activity3.class);
i.putExtra("Key", "Value");
startActivity(i);

And inside Activity3, you can get data using

String data = getIntent().getStringExtra("Key");

Also as this is very simple part, you should research it on google before asking in Stackoverflow.

look for it to work properly you should make the following changes.

you must change this:

        if (condition) {
            Hero = arrayP.get(0).name;
            Intent i = new Intent(Activity2.this, Activity3.class);
            i.putExtra("name");
            startActivity(i);

        }

to:

            if (condition) {
                String heroName = arrayP.get(0).name; // assuming that name is a String and that arrayP is a Hero Array
                Intent i = new Intent(Activity2.this, Activity3.class);
                i.putExtra("name", heroName); // change
                startActivity(i);

            }
