Attempt To Invoke Virtual Method On A Null Object Reference For Video_id

I Am getting this error java.lang.RuntimeException: Unable to instantiate activity ComponentInfo

Solution 1:

getIntent() would return null unless onCreate method is called. You are using getIntent from a field initializer.

Change

Productproduct= (Product) getIntent().getSerializableExtra("product");

to

Product product;

and add this to onCreate method

product = (Product) getIntent().getSerializableExtra("product");
