Getting exception when starting new activity on an android?

You should've posted the stacktrace, but I assume the error is on this line in your target activity: button. SetOnClickListener(scoreBtnListener) This will give you a NULL : Button button = (Button)findViewById(R.id. Button1) because you haven't set a contentview in THAT activity, so there is nothing for findViewById() to return.

You'll get a nullpointer when calling that setOnclickLIstener().

Uvs: to add to this - place setContentView() call right after the super. OnCreate(savedInstanceState). – Arhimed Oct 8 at 20:00.

Called when the activity is first created. Intent mintent = new Intent(HelloworldActivity. Button button = (Button)findViewById(R.id.

Intent intent = new Intent(imgScoring. TextView tv = (TextView)findViewById(R.id. /** Called when the activity is first created.

Button button = (Button)findViewById(R.id. Button = (Button)findViewById(R.id.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
