                        // String strCMP= spDepCMPName.getSelectedItem().toString();

           //startActivity(new Intent(DepositActivity.this, AuditPointDetailsActivity.class).putExtra("insert_row_index",""+long_insert_row_index).putExtra("segment_name", spinner_segment.getSelectedItem().toString()).putExtra("audit_type_name", spinner_audit_type.getSelectedItem().toString()).putExtra("audit_type_id", audit_type_id).putExtra("segment_id", segment_id));


///please see commented section at bottom
                      startActivity(new Intent(DepositActivity.this, DepositeNextActivity.class)

                                .putExtra("CMPName", depositecmpname));
                    }else {
                        Toast.makeText(DepositActivity.this,"Error while inserting data.Please re-enter data.",Toast.LENGTH_LONG).show();

Answer 1

you can use code in your first activity like :-

  ArrayList<String> arr = new ArrayList<String>();
    arr.add(long_insert_row_index);
    arr.add( depositecmpname);
    Intent intent = new Intent(firstactivity.this,secondActivity.class);
                intent.putExtra("array_list", arr);
                startActivity(intent);

Now in another class you can use this code saying :-

Bundle extras = getIntent().getExtras();

ArrayList<String> arr = (ArrayList<String>)extras.getStringArrayList("array_list");
          Toast.makeText(getApplicationContext(),""+arr.size(),Toast.LENGTH_LONG).show();

hope it will help

Answer 2

Use for open activity:

Intent intent = new Intent(activity, Activity2.class);
            intent.putExtra("String1", "Hello!");
            intent.putExtra("String2", "Hello!2")
            activity.startActivity(intent);

In open activity:

getIntent.getStringExtra("String1");
getIntent.getStringExtra("String2");

Or use

intent.putExtra("StringByteArr", "str".toByteArray());

and:

String.valueOf(getIntent.getByteArrayExtra("StringByteArr"));
