You should post the code that calls this class (likely your Activity
). 您应该发布调用此类的代码(可能是Activity
)。 There are some common problems that could cause this, like the NetworkOnMainThreadException . 可能会导致一些常见问题,例如NetworkOnMainThreadException 。
I wrote some working Android mail code based on the same javax.mail
code, and it works correctly. 我基于相同的javax.mail
代码编写了一些有效的Android邮件代码,并且可以正常工作。 Here's the code: 这是代码:
submitButton.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
/*
* Send email in a background thread
*/
Thread t = new Thread(new Runnable() {
@Override
public void run() {
// retrieve the configuration values from preferences
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(theActivity);
String destinationAddress = preferences.getString("email_destination_address", theActivity.getString(R.string.default_email_destination_address));
String senderAddress = preferences.getString("email_from", theActivity.getString(R.string.default_email_sender_address));
String senderPassword = preferences.getString("email_password", theActivity.getString(R.string.default_email_sender_password));
String smtpServer = preferences.getString("email_server", theActivity.getString(R.string.default_smtp_server));
Mail m = new Mail(senderAddress, senderPassword);
String[] toArr = { destinationAddress };
m.setHost(smtpServer);
m.setTo(toArr);
m.setFrom(EMAIL_USERNAME);
m.setSubject(getString(R.string.email_subject, barcode));
m.setBody(getString(R.string.email_body));
try {
ArrayList<String> filesToSend = theAdapter.getFilenames();
for (String file : filesToSend)
{
m.addAttachment(file);
}
if (m.send()) {
Log.d(TAG, "EMAIL SENT SUCCESSFULLY");
} else {
Log.w(TAG, "EMAIL NOT SENT");
}
} catch (Exception e) {
Log.e(TAG, "Could not send email", e);
}
}
});
t.start();
Toast.makeText(getApplicationContext(), getString(R.string.email_sending), Toast.LENGTH_LONG).show();
theActivity.onBackPressed();
}
});
Note: if I were writing this code today I might use an AsyncTask
instead of a Thread, but either are considered valid. 注意:如果我今天正在编写此代码,则可能会使用AsyncTask
而不是Thread,但AsyncTask
被视为有效。
You are missing the rest of the code for getters and setters. 您缺少用于获取器和设置器的其余代码。 See the comment at the bottom of your code: 请参阅代码底部的注释:
// more of the getters and setters …..
You need to add the following in place of that comment: 您需要添加以下内容代替该注释:
/**
* METHOD TO SET THE "TO" STRING ARRAY
* @param toArr
*/
public void setTo(String[] toArr) {
this._to = toArr;
}
/**
* METHOD TO GET THE "TO" STRING ARRAY
* @return
*/
public String[] getTo() {
return _to;
}
/**
* METHOD TO SET THE "FROM" FIELD FOR THE MESSAGE
* @param string
*/
public void setFrom(String string) {
this._from = string;
}
/**
* METHOD TO GET THE "FROM" FIELD FOR THE MESSAGE
* @return
*/
public String getFrom() {
return _from;
}
/**
* METHOD TO SET THE MESSAGE SUBJECT
* @param string
*/
public void setSubject(String string) {
this._subject = string;
}
/**
* METHOD TO GET THE MESSAGE SUBJECT
* @return
*/
public String getSubject() {
return _subject;
}
This should work. 这应该工作。 The next obstacle you will face will be what DShaw mentions below about the NetworkOnMainThreadException , which can be fixed by either using this post to not check StrictMode, but the better option is to use AsyncTask as is discussed in this post. 你将面临的下一个障碍将是什么DShaw低于提到有关NetworkOnMainThreadException ,这可以通过使用这个固定后不检查StrictMode,但更好的选择是使用的AsyncTask在讨论这个职位。
[EDIT] I also had a problem with proguard! [编辑]我对proguard也有问题! If none of the above works, try to disable proguard to see if it works then. 如果以上方法均无效,请尝试禁用proguard,以查看其是否有效。
Hope this helps. 希望这可以帮助。
