sync

问题 I'm writing a simple app to monitor sync activities on Android and am stuck with SyncInfo.startTime which returns a value based on SystemClock.elapsedRealTime() . How do I convert this value to a regular Date object? 回答1: Found a solution to the problem: new Date(System.currentTimeMillis() - SystemClock.elapsedRealtime() + elapsedTime); where elapsedTime is the time I receive from Android.

This remap does correctly display of both the column-header names and column-body data in the new order and based on user preferences

问题 I've recently set up an app id and provisioning profile and was able to test my app on the device successfully. I then downloaded some sample iOS XCode projects and upon deploying one of them and deleting the sample app from the phone have since been unable to sync the phone with iTunes or see it as connected in the Xcode organizer window (the device is still listed in the lefthand pane, but shows up as disconnected).

问题 I'm doing the sync to mirror a sqlite DB to a server one. I have a Master-Detail table, where the details must be send to the server ASAP. However, is possible that detail 3 arrive before detail 2. I need to mimic the steps made to the document and respect the order of the operations.

问题 I am developing a Django application which will use multiple database backends. I would like to put an sqlite database on the machine running the django application, and sync to a remote mysql database.
