コードで何をすべきか本当にわかりません。ここで提案されたコードをstackoverflowですでに試しましたが、それでも適切な非同期タスクまたはスレッドを取得できませんでした。これらの推奨コードを試すと、常にエラーが発生します。誰かが正しい非同期タスクまたはスレッドを実行する方法を教えてください。ここに私のコードがあります:
final Button send = (Button) this.findViewById(R.id.send);
send.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
try {
GMailSender sender = new GMailSender((from.getText().toString()),
(pass.getText().toString()));
sender.sendMail((subject.getText().toString()),
(body.getText().toString()),
(from.getText().toString()),
(to.getText().toString()));
} catch (Exception e) {
Log.e("SendMail", e.getMessage(), e);
}
}
});
ここに私のGmailSenderがあります:

private String mailhost = "smtp.gmail.com";
private String user;
private String password;

private String[] _to;

message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(recipients));
else
message.setRecipient(Message.RecipientType.TO, new

}catch(Exception e){
}
}

何度もこのような質問をして申し訳ありません。私は正しい答えを得ることができません。どんな助けでも大歓迎です。よろしくお願いします.. TT .
