Olá,
por favor me ajudem, não sei o que estou fazendo de errado. Esse método executa e dá erro:
public void progresso() {
dao = new DAO(this);
if (dao.isEmpty()) {
progressDialog = ProgressDialog.show(this, "",
"Salvando todas as frases...");
new Thread(new Runnable() {
public void run() {
try {
dao.insert("uma string");
progressDialog.dismiss();
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
}
}
Só para constar, assim ele funciona, só que sem o ProgressDialog:
public void progresso() {
dao = new DAO(this);
if (dao.isEmpty()) {
dao.insert("uma string");
}
}
Para poderem analisar melhor segue o construtor dessa classe DAO que eu fiz:
public DAO(Context context) {
this.context = context;
Helper helper = new Helper(this.context);
this.bancoDeDados = helper.getWritableDatabase();
this.insertStatement = this.bancoDeDados.compileStatement(INSERT);
}
O erro que dá no LogCat é esse:
