Question

In my app i use Intent for start an activity, but the exception say this:
java.lang.NullPointerException:

Attempt to invoke virtual method 'android.content.Intent android.content. Intent.setClass(android.content.Context, java.lang.Class)' on a null object reference

and this is the code:
Intent i = new Intent(getApplicationContext(), MyActivity.class);
startActivity(i);
How can i do?

Answer 1

Try
Intent i = new Intent(CurrentActivity.this, MyActivity.class);
startActivity(i);
Where current Activity is the Activity you are trying to move from
