如何code A＆QUOT;现在＆QUOT同步;运行在Android？ [英] How to code a "sync now" operation on Android?

问题描述

我有一个同步适配器用于我的DB和在应用程序的使用的某些点，它需要现在来同步数据块。我想触发同步适配器，如果同步时弹出，然后重新建立同步时间（即4小时这个现在同步事件）。

I have a sync adapter for my DB and at certain points in the application usage, it needs to sync the DB now. I would like to trigger the sync adapter as if its sync-time popped and then re-establish the sync time (i.e., 4 hours from this 'sync now" event).

推荐答案

我觉得（未测试）一个更好的解决方案是在ContentResolver的已定义。

I think (not tested) a better solution is already defined in the ContentResolver.

ContentResolver.requestSync(account, authority, extras);

所以人们不妨做到以下几点：

so one might do the following:

AccountManager am = AccountManager.get(context);
Account account =  null;
am.getAccountsByType(mytype);
for(Account a : accounts) {
    if (am.getUserData(account, key)) {
        account = a;
        break;
    }
}
Bundle extras = new Bundle();
extras.putString(EXTRA_mystuff, myvalue);
ContentResolver.requestSync(account, authority, extras)
