Desculpe, este pode ser um erro simples, novo no desenvolvedor do Android, mas estou pesquisando na Web procurando respostas e nenhuma dessas soluções parece funcionar. Toda vez que tento executar o código abaixo, ele falha, alguma idéia de por que / como corrigi-lo. Primeiro é o arquivo java

public class Services extends Activity {
Report2 r;  
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Bundle data = getIntent().getExtras();

    r = data.getParcelable("RemarksReport");

    setContentView(R.layout.activity_services);

    TextView sampleText = (TextView) findViewById(R.id.services_text);

funciona até aqui, depois trava na próxima linha

    sampleText.setText("ANYTHING");

    if (savedInstanceState == null) {
        getFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment()).commit();
    }
}

A parte do arquivo XML se parece com isso,

        <TextView
        android:id="@+id/services_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textColor="#000000"
        android:textSize="42px"
        android:text="@string/sample_services" />

onde isso está dentro de uma tabela, em um layout linear.
