如何显示同步失败的消息 [英] How to show sync failed message

问题描述

我已经建立的联系人同步适配器。这是所有工作正常，但我需要一件事。如果由于某种原因同步未成功完成，我想告诉像谷歌帐户的消息显示了当同步失败

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

解决的办法是设置在同步造成的延迟。这种延迟后，同步将被重新启动。

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;
}
