使用AccountManager令牌進行IMAP/SMTP驗證

Question

我正在嘗試使用從Android的AccountManager接收到的令牌來代替使用用戶名和密碼來實現簡單的IMAP/SMTP gmail客戶端。 我試圖使用「郵件」作爲authTokenType參數getAuthToken（）。

谷歌提供SMTP/IMAP的這個例子用的oauth2 http://code.google.com/p/google-mail-oauth2-tools/source/browse/#svn%2Ftrunk%2Fjava%2Fcom%2Fgoogle%2Fcode%2Fsamples%2Foauth2 http://code.google.com/p/google-mail-oauth2-tools/wiki/JavaSampleCode

，但它是爲Java。 在我的Android項目中使用它有一些導入（關於SASL）缺失。爲了解決這些問題我使用這個庫http://code.google.com/p/asmack/

的例子編譯，但我注意到，在運行時出現問題

似乎asmack使用org.apache.harmony.javax.security。*而不是javax.security 。*

有人遇到過這個問題嗎？ Google在他們的例子中似乎沒有考慮這種可能性，但我認爲它應該是用戶的共同特徵。

謝謝。

Answer 1

從日誌中，它看起來像你有java6和java7文件混合起來。你能分享你的類路徑細節嗎？

另一種可能性是您沒有正確的憑證，無論是登錄還是密碼都不正確。

我已經嘗試過你所擁有的，它已經工作了，應該是直截了當的。

Answer 2

爲了使用ASMACK認證者用JavaMail我創建可在這裏圖書館的一個補丁版本：http://www.mannaz.at/codebase/imap-ssl-mail-android/

它是基於http://code.google.com/p/javamail-android/但支持ASMACK SASSL認證。

該類從JAR文件中丟失。只需將它添加到你的源代碼：

package com.falott.ingresss.util; 
public class Log { 
    public static boolean loggingEnabled(){ 
     return false; 
    } 
}
