美好的一天,我正在编写有关捕获已发送邮件的应用程序。一切正常,每当我尝试发送短信时都会调用ContentObserver,但是在 onChange(boolean selfChange)方法中,应用程序会删除:
。当我通过Step Over(F8)对其进行重新排序时,在这一行上它打开了一个 Looper.java ,然后单击 http://imgur.com/a/uh4Dl ...如何要解决这个问题吗?我希望你能理解我的问题并抱歉我的英语不好。非常感谢你!

确保您正在注册正确的内容路径。例如: -
Inbox = "content://sms/inbox"
Failed = "content://sms/failed"
Queued = "content://sms/queued"
Sent = "content://sms/sent"
Draft = "content://sms/draft"
Outbox = "content://sms/outbox"
Undelivered = "content://sms/undelivered"
All = "content://sms/all"
Conversations = "content://sms/conversations".
contentResolver.registerContentObserver(Uri.parse("content://sms/outbox"), true, new mObserver(new Handler()));
同样在cursor.query上使用相同的路径
