getIntent().getSerializableExtra is null

Question

I have a POJO class implements Serializable and I want to transfer an object of this class to another activity with a help Intent and Bundle. I checked the object before the transfer, it is not null. (Correctly get one of attributes)

put:

private void onFriendClick(FriendHolder holder, int position) {
        Intent intent = new Intent(context, ProfileActivity.class);
        Bundle extra = new Bundle();
        extra.putSerializable(Consts.KEY_USER_JSON,  friendList.get(position));
        intent.putExtra(Consts.KEY_USER_JSON, extra);
        Log.e("onFriendClick", String.valueOf(friendList.get(position).getName()));
        context.startActivity(intent);
    }

get from another activity:

 private void setupProfile() {
        Bundle extras = getIntent().getExtras();
        if (extras != null) {
            profile = (ProfileDTO) getIntent().getSerializableExtra(Consts.KEY_USER_JSON);
            Log.e("onFriendClick", String.valueOf(profile.getName()));//NPE this
        } else profile = user.getProfile();
    }

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String ru.techmas.getmeet.api.models.ProfileDTO.getName()' on a null object reference at ru.techmas.getmeet.activities.ProfileActivity.setupJsonProfile(ProfileActivity.java:103)

You don't need to create a Bundle. Try doing:

private void onFriendClick(FriendHolder holder, int position) {
    Intent intent = new Intent(context, ProfileActivity.class);
    intent.putExtra(Consts.KEY_USER_JSON,  friendList.get(position));
    Log.e("onFriendClick", String.valueOf(friendList.get(position).getName()));
    context.startActivity(intent);
}

private void setupProfile() {
    if (getIntent().getSerializableExtra(Consts.KEY_USER_JSON) != null) {
        profile = (ProfileDTO) getIntent().getSerializableExtra(Consts.KEY_USER_JSON); 
        Log.e("onFriendClick", String.valueOf(profile.getName()));//NPE this
    } else {
        profile = user.getProfile();
    }
}

But if still want to use the Bundle, you should replace in the code that you posted:

profile = (ProfileDTO) getIntent().getSerializableExtra(Consts.KEY_USER_JSON);

By:

profile = (ProfileDTO) extras.getSerializableExtra(Consts.KEY_USER_JSON);
