我正在尝试使用 GMailSender 直接从我的应用程序发送电子邮件

我的 fragment :

公共(public)类 updateFragment 扩展 SherlockFragment {

public View onCreateView(LayoutInflater inflater, ViewGroup group, Bundle saved)
{
View v = inflater.inflate(R.layout.update_layout, group, false);





Button buttonsubmit = (Button) v.findViewById(R.id.buttonsubmit);
buttonsubmit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

try {
GMailSender sender = new GMailSender("test@gmail.com", "test");
sender.sendMail("Update info",
"",
"test@gmail.com", "test@gmail.com");
Toast.makeText(updateFragment.this.getActivity().getBaseContext(), "Info Submitted Successfully", Toast.LENGTH_SHORT).show();

} catch (Exception e) {
Log.e("SendMail", e.getMessage(), e);
Toast.makeText(updateFragment.this.getActivity().getBaseContext(), "Please make sure that you have an internet connection", Toast.LENGTH_SHORT).show();
}




}

});

return v;

}
}

它工作正常,但如果没有连接,它会看起来工作正常,我的意思是 toast 会说“信息提交成功”,为什么它没有导致或捕获异常??

提前致谢

最佳答案

这是因为GMailSender.sendMail 已经捕获异常。删除 GMailSender.sendMail 中的 try catch block ,您将得到异常。
