Up Button Calls OnDestroy Of Parent Activity

Right off the top, I want to clarify something: The button that I am struggling with is NOT the back button. I am referring to the up/home button in the ActionBar / Toolbar at the

Solution 1:

I don't know why default up button implementation creates a new activity but a working solution for me is to override onOptionsItemSelected:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if(id== android.R.id.home ){
        onBackPressed();
        return true;
    }
    return super.onOptionsItemSelected(item);
}

Also this solution works for me:

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                Intent intent = NavUtils.getParentActivityIntent(this);
                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                        | Intent.FLAG_ACTIVITY_SINGLE_TOP);
                NavUtils.navigateUpTo(this, intent);
                return true;
            default:
                break;
        }
        return super.onOptionsItemSelected(item);
    }

Solution 2:

I had this problem too, and after a little more digging found the correct solution is to make a change in the manifest to add the following to your parent activity:

android:launchMode="singleTop"
