我尝试发送2封电子邮件：一封是应用，一封是后台。我已在背景中使用https://github.com/yesidlazaro/GmailBackground作为电子邮件。
应用程序的电子邮件按钮有效。我在尝试其他按钮时发送邮件时收到错误消息getSlotFromBufferLocked：未知缓冲区：0xb2bba960。我不确定我的其他按钮出了什么问题。我改变了一点＆amp;它仍然没有工作＆amp;我已经证明了这些错误。我有什么想法吗？
public class Sad extends AppCompatActivity {
Button button2;
Button button3;
final Context context = this;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sad);
}
public void onClick (View v) {
switch (v.getId()) {
case R.id.button2:
Intent h = new Intent(Intent.ACTION_SEND);
h.setType("message/rfc822");
h.putExtra(Intent.EXTRA_EMAIL , new String[]{"email"});
h.putExtra(Intent.EXTRA_SUBJECT, "Something bothers me");
h.putExtra(Intent.EXTRA_TEXT , "body of email");
try {
startActivity(Intent.createChooser(h, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(Sad.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
break;
case R.id.button3:
BackgroundMail.newBuilder(this)
.withUsername("*****@gmail.com")
.withPassword("p/w")
.withMailto("*********")
.withSubject("Something bothers me")
.withBody("this is the body")
.withOnSuccessCallback(new BackgroundMail.OnSuccessCallback() {
@Override
public void onSuccess() {
//do some magic
}
})
.withOnFailCallback(new BackgroundMail.OnFailCallback() {
@Override
public void onFail() {
//do some magic
}
})
.send();
}
;
}}
这一点真的令人困惑，它似乎有助于两种不同的方式来发送电子邮件＆amp;一些代码未使用。

看起来您无法进行身份验证。如果你肯定不是这种情况，你会想要抓住这个错误，看看你是否可以从中获得更多细节。也许GMail不允许您使用基本身份验证，而是需要安全身份验证。
