Android-FeedBack
选择
之前开发OverHust的时候,需要用到用户反馈这一功能,于是就在考虑怎么实现用户反馈这一功能。
目前,常规方法如下:
利用第三方服务,例如:友盟
调用用户已登录的邮箱帐号发送邮件
利用第三方服务
优点
:使用第三方服务,只需要调用接口,简单粗暴。
缺点
:导入Library工程,自定义度不高。如果仅仅会用到第三方的用户反馈这一服务的话,更没必要导入别人的Library工程。
调用用户已登录的邮箱帐号发送邮件
优点
:直接调用系统的发送邮件服务,更加简单粗暴。
缺点
:如果用户没有在系统中登录邮箱帐号,那就悲剧了。
详细了解上述两种方法各自的优劣之后,发现他们都不能很好的满足需求,因此,另谋出路。于是就在stackoverflow上发现可以用JavaMail API
来实现。首先,不用导入一些其他Library工程,其次虽然也是用邮件服务,但是发信邮件帐号是在应用内指定的,与用户无关。当然,也是由于我自己想体验一下JavaMail API
,之后开发应用还是更多的会用第三方服务,因为第三方服务有很多我用的着的功能。
实现
具体实现是参照stackoverflow上的 Sending Email in Android using JavaMail API without using the default/built-in app
首先,在工程中导入这三个jar, mail.jar , activation.jar , additionnal.jar.
之后,写几个工具类就ok了(附上我项目中的这几个类)。
