lblMin.setText(String.valueOf(jour.getmTempMin()));

lblMax.setText(String.valueOf(jour.getmTempMax()));

(Just assumption, less info of Exception stacktrace)

​

I think, this line, incercari.setText(valIncercari); throws Exception because valIncercari is int

​

So it should be,

​

incercari.setText(valIncercari+"");

Or

​

incercari.setText(Integer.toString(valIncercari));
