我有一段非常简单的代码，用于安排我的下一次同步操作。它在扩展 AbstractThreadedSyncAdapter 的 SyncAdapter 内运行——因此使用它的上下文。它为仅管理 SyncAdapter 的 BroadcastReceiver“MyService”启动的 PendingIntent。

我只是想安排它在 24 小时内重现。

private void scheduleNextSync(Long timeFromNow) {
    Intent intentSync = new Intent(getContext(), MyService.class);
    intentSync.setAction(Intent.ACTION_SYNC);
    intentSync.addCategory("android.provider.CONTACTS_STRUCTURE");
    intentSync.putExtra(MySyncAdapter.EXTRA_SYNC_TYPE, "");
    intentSync.putExtra(MySyncAdapter.EXTRA_RESOLVE_METAID, false);

    int flags = 0;
    int request = REQUEST_SYNC_ALL;
    PendingIntent piSync = PendingIntent.getBroadcast(getContext(), request, intentSync, flags);
    //
    Log.i(TAG, "schedulePendingSync: " + piSync.toString());
    AlarmManager alarm = (AlarmManager) getContext().getSystemService(Activity.ALARM_SERVICE);
    alarm.set(request, SystemClock.elapsedRealtime() + timeFromNow, piSync);
}

日志输出：

您PendingIntent.getBroadcast并使用我在Alarm doc和PendingIntent doc 中找不到该常量alarm.set的请求。REQUEST_SYNC_ALL

也许我与最新的 SDK 不同步 :)
