如何显示同步失败消息

How to show sync failed message(如何显示同步失败消息)

问题描述

我已经构建了一个联系人同步适配器.一切正常，但我还需要一件事.如果由于某种原因同步未成功完成，我想在同步失败时显示一条消息，例如 Google 帐户正在显示

I've build a contacts sync adapter. It's all working fine but I need one more thing. If for some reason the sync does not complete successfully, I want to show a message like Google account is showing when the sync fails

推荐答案

解决方案是设置同步结果的延迟.在此延迟之后，同步将重新启动.

The solution was to set the delay on the sync result. After this delay the sync will be restarted.

try {
    DO THE SYNCHRONIZATION
} catch (AuthenticationException e) {
    Log.e(TAG, "AuthenticationException");
    syncResult.stats.numAuthExceptions++;
    syncResult.delayUntil = 180;
} catch (ParseException e) {
    Log.e(TAG, "ParseException");
    syncResult.stats.numParseExceptions++;
} catch (IOException e) {
    Log.e(TAG, "IOException");
    syncResult.stats.numIoExceptions++;
    syncResult.delayUntil = 180;
}
