AndroidのGmailSenderでSDのファイルを添付しようとしています。
私はこれを持っています: GMailSender を介して添付ファイル付きのメールを送信しますか?
ファイルが存在することを確認しましたが、メールが正しく送信されません。ファイルが添付されていない同じ方法は問題なく実行されます。
問題は何でしょうか？
どうも。
File imageFile = new File("/sdcard/prueba.jpg");
if (imageFile.exists()){
Toast.makeText(getApplicationContext(),"Existe",Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getApplicationContext(),"NO Existe", Toast.LENGTH_LONG).show();
}
gmail.sendMail("Datos", c.getMailBody(),Constants.getAddress(), udb.getMail(), imageFile);
