Using Intents

1. In the sending Activity, create an Intent and put the data you want to pass using putExtra() method. For example:

Intent intent = new Intent(this, ReceivingActivity.class);
intent.putExtra("key", "Value to pass");
startActivity(intent);

2. In the receiving Activity, retrieve the data from the Intent using getIntent() and getStringExtra() (or the appropriate method based on the data type). For example:

String value = getIntent().getStringExtra("key");

Using Bundles

1. Create a Bundle in the sending Activity and put the data you want to pass using putString(), putInt(), etc. For example:

Bundle bundle = new Bundle();
bundle.putString("key", "Value to pass");
intent.putExtras(bundle);

Bundle bundle = getIntent().getExtras();
String value = bundle.getString("key");
