} 

but the code is giving me error i dont know why.. i have added second activity to manifest file.. please guide what mistake i am doing ???

Answer 1

Can you debug the code, or perhaps include some try/catch-blocks, to try and detect where the error is happening, and what the error message is?

Other than that, try doing it this way instead:

Intent intent = new Intent(DataPassing.this, DataPassing2.class); 
intent.putExtra("key", 1123); 

startActivity(intent); 

... and still fetch the bundle in DataPassing2 as you have been before. I don't know if it'll help, because I don't know much about what your error is, but it might.
