當發送短信時，應用程序停止在getContentResolver（）。查詢（...）

Question

美好的一天，我正在編寫有關捕獲已發送消息的應用程序。一切正常，該ContentObserver被稱爲每次當我嘗試發送短信，但在的onChange（布爾selfChange）方法應用在下降。

• 光標CUR = getContentResolver（）查詢（uriSMS， NULL，NULL，NULL，NULL） ..............................屏幕http://imgur.com/a/hE94K

在TrackerService .java在mObserver。當我通過Step Over（F8）去嘗試，在這條線上，它打開我一個Looper.java並在此行上刪除http://imgur.com/a/uh4Dl ...如何解決工作請？我希望你能理解我的問題，併爲我的英語不好而感到抱歉。非常感謝！

確保您正在註冊正確的內容路徑。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())); 

類似地使用相同的路徑上的cursor.query
