Rudson estou usando:

android:targetSdkVersion="17"

Usando Sherlock com support library.

Ubiratan poderia explicar melhor em que momento o getActivity() retorna null?

Galera, algo curioso aconteceu hoje, antes vou explicar o cenário:

Tenho um Fragment o qual tem a resposta de um AsynkTask (webservice). Se o resultado for TRUE então eu envio uma mensagem de "OK" na tela utilizando o Toast.

Por utilizar um Fragment, ao chamar o Toast passo como contexto o getActivity() - porém, hoje ocorreu um exception:

FATAL EXCEPTION: main

java.lang.NullPointerException

at android.widget.Toast.<init>(Toast.java:89)

at android.widget.Toast.makeText(Toast.java:231)

at br.com.fsoft.tablet.interno.utils.AlertaToast.<init>(AlertaToast.java:10)

at br.com.fsoft.tablet.interno.fragments.TabFragmentSinc.onRequestEnd(TabFragmentSinc.java:523)

Sempre funcionou assim (mais de 2 meses) porém hoje, pela primeira vez, ocorreu esse erro.

O erro se refere ao getActivity() nulo! Não entendi muito bem o porque.

Alguém já passou por isso? Porque isso ocorre?
