Olá a todos,

ao tentar executar meu projeto no emulador do Android, apareceu esse erro:

The application (nome da app)(process(nome do pacote)) has stopped unexpectedly. Please try again.

Coloquei o projeto em anexo.

Abaixo, o que apareceu no logcat até antes de eu clicar “force close”:

Olá,

olhei o teu projeto e vi que o erro está aqui:

Classe Tela1

EditText cxNome = (EditText)findViewById(R.id.inputNomeEditText);
	EditText cxEmail = (EditText)findViewById(R.id.inputEmailEditText);
	Button btnProximo1 = (Button)findViewById(R.id.tela01ProximoButton);
	TextView status = (TextView)findViewById(R.id.statusTela1TextView);
	
    public void onCreate(Bundle savedInstanceState) {       
    	super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
                
        btnProximo1.setOnClickListener(this);
        
        Log.v("curso", "Tela1 - executando método onCreate");
    }

tenta assim:

        EditText cxNome ;
	EditText cxEmail ;
	Button btnProximo1;
	TextView status ;
	
    public void onCreate(Bundle savedInstanceState) {       
    	super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        cxNome = (EditText)findViewById(R.id.inputNomeEditText); 
        cxEmail = (EditText)findViewById(R.id.inputEmailEditText);
        btnProximo1 = (Button)findViewById(R.id.tela01ProximoButton);
        status = (TextView)findViewById(R.id.statusTela1TextView);
        btnProximo1.setOnClickListener(this);
        
        Log.v("curso", "Tela1 - executando método onCreate");
    }

Obs¹:
o erro está dando porque o findViewById() busca no layout da Activy e voce está setando o layout no onCreate… então tem que usar o findViewById() depois que setar o layout da Activity.

Obs²:
Ajuste nas outras Classes também…

Abçs…
