Javamail is Sun's application interface for email processing. It provides some of the most common implementation methods for mail transfer protocols and provides easy methods to call them. Javamail is an application interface released by Sun, so it is not included by JDK yet. Therefore, you need to download the javamail package from Sun's official website. In addition, sun's JAF (JavaBeans activation framework) is also required. Otherwise, javamail cannot run.
The core javamail API consists of s

Watch out! Calling methods onAccountManagerCan be tricky! Since account operations may involve network communication, most ofAccountManagerMethods are asynchronous. This means that instead of doing all of your auth work in one function, you need to implement it as a series of callbacks. For example:
AccountManager am = AccountManager.get(this);Bundle options = new Bundle();am.getAuthToken( myAccount_, // Account retrieved

5. Use the Javax.mail.Transport tool class to send mail.
Here I refer to the written message class is only support SMTP and not support the other two, so there is no time to write the factory class. But SMTP should be enough. Today TX has a bug send not go out to change a mailbox is OK.

Generally, we use authenticator to encapsulate username and password, opaque! So:

actually a type of dynamic cipher. Dynamic Password is also called a one-time password, which means that the user's password is constantly changing according to time or usage, and each password is used only once. Because each password used must be generated by a dynamic token and the user's password is different each time, it is difficult for a hacker to calculate the next dynamic password that appears. But dynamic passwords require a high demand for mobile phones, and smartphones like the ipho
Okhttp provides support for user authentication. When the status code for the HTTP response is 401, okhttp gets the new request object from the Set authenticator object and attempts to make the request again. The Authenticate method in the authenticator interface is used to provide a request object for authentication, and the Authenticateproxy method is used to provide a request object that authenticates th
