我一直在开发一个会发送2封电子邮件的应用，一个按钮会发送一封电子邮件，电子邮件客户端会打开，另一个会在后台发送。 我尝试使用Gmail发件人在后台发送应用。随应用程序发送的按钮有效，但当我按下另一个按钮时应用程序停止工作我收到以下错误消息。

请你让我知道我哪里出错了？ （******是电子邮件地址和密码。）
public class Happy extends AppCompatActivity {
Button button2;
Button button3;
final Context context = this;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_happy);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.button:
Intent h = new Intent(Intent.ACTION_SEND);
h.setType("message/rfc822");
h.putExtra(Intent.EXTRA_EMAIL , new String[]{"***************"});
h.putExtra(Intent.EXTRA_SUBJECT, "I'm happy");
h.putExtra(Intent.EXTRA_TEXT , "body of email");
try {
startActivity(Intent.createChooser(h, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(Happy.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
break;
case R.id.button01:
BackgroundMail.newBuilder(this)
.withUsername("************")
.withPassword("*********")
.withMailto("**************")
.withSubject("this is the subject")
.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();
//BackgroundMail bm = new BackgroundMail(context);
// bm.setGmailUserName("***************");
//bm.setGmailPassword("***********");
//bm.setMailTo("*************");
//bm.setFormSubject("I'm Happy");
//bm.setFormBody("No comment");
//bm.send();
break;
}
;
我注意到这个类中的很多方法没有被使用我认为这可能是问题的原因但我不确定如何纠正它。
