在 Android 中获取来自 Gmail 的邮件列表

有这样的问题：我需要从我的 Gmail 帐户获取邮件列表。它如下面的代码片段所示：

Account[] accounts = AccountManager.get(this).getAccountsByType("com.google");
File file = new File("content://gmail-ls/messages/"+accounts[0].name+"/");
if(file.exists())
{
    Uri uri = Uri.parse("content://gmail-ls/messages"+accounts[0].name+"/");
    cursor = this.getContentResolver().query(uri, null, null, null, null);
}

但它不会进入“if”条件，因为这样的路径不存在。如果没有“if”条件，当我通过 Uri 的查询将游标分配给 gmail-ls 时，它会抛出异常。有谁知道这个问题如何解决？将不胜感激任何建议！

Have such kind of problem: I need to get list of mails form my gmail account. It`s shown in snippet below:

Account[] accounts = AccountManager.get(this).getAccountsByType("com.google");
File file = new File("content://gmail-ls/messages/"+accounts[0].name+"/");
if(file.exists())
{
    Uri uri = Uri.parse("content://gmail-ls/messages"+accounts[0].name+"/");
    cursor = this.getContentResolver().query(uri, null, null, null, null);
}

But it doesn't enter in "if" condition as such path does not exist. With out "if" condition it throws with exception on moment when I assign a cursor by a query with Uri to gmail-ls.
Anyone knows how this problem can be solved? Will appreciate any advice!
