我编写了一个示例应用程序，它从GAL返回联系人数据（公司目录，在＆＃34; Accounts＆＃34中定义为Exchange ActiveSync;）。同样的应用程序在一堆不同的设备上运行得非常好，但在我测试的HTC上却没有（One X +与Android 4.1.1和One VX与4.0.4）。
基本上，对ContactsContract.Directory.CONTENT_URI的查询仅返回ID为Directory.DEFAULT和Directory.LOCAL_INVISIBLE的目录。在其他设备上，例如，使用类型com.android.exchange添加id = 5。从本地＆＃34;人物＆＃34;应用程序也适用于HTC。
这是两个类的完整代码清单

此外，还有this app, "True contacts"，这基本上只是最新的ICS联系人应用程序编译的库存。例如，它在三星Galaxy S3上完美搜索GAL，但不在HTC上搜索。请问有人对这个问题有所了解吗？
