Answer 1

Converting comments to answer

By looking at the logcat we can see that the problem is at line 41 of QuestionActivity. So we know that currentGame is null.

You need to set breakpoints before that and see what is causing that to be null. You may have found that other variables/objects arenull which ends up causing the NPE.

Answer 2

Context is wrong, just change:

startActivity(new Intent(this, QuestionnActivity.class));

to:

startActivity(new Intent(LoActivity.this, QuestionnActivity.class));
