Returning from activity B->A via Android HOME button does not restore intent

Question

I have activity A that gets passed a long ID value via long extra, when the activity is initially launched. When I go from A-B, and then press home, the ID value is gone. How can I restore it?

When going from A->B

Intent intent = new Intent(A.this, B.class);
startActivity(intent);

I've tried:

• Using bundle in onSaveInstanceState, onRestoreInstanceState

• Getting the ID from getIntent in onResume

• Getting the ID from getIntent in onCreate
• Getting the ID from saved bundle in onCreate (it's always null, even when onSaveInstanceState is called)
• Overriding onFinish in activity B Explicitly handling
  android.R.id.home case in onOptionsItemSelected in Activity B

Answer 1

what is onFinish in your code?

try this code in your B Activity to get it finish when you press up button in actionbar

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    // Respond to the action bar's Up/Home button
    case android.R.id.home:
        finish();
        return true;
    }
    return super.onOptionsItemSelected(item);
}
