我使用谷歌驱动器API为Android访问谷歌驱动器中的文件。上传新文件时,我的应用程序可以访问该文件需要3到15分钟。我试图添加requestSync以偶尔强制同步,但每次运行它时都会出现“超出同步请求限制”。有什么东西可以让我达到极限,还是有不同的问题?
代码的RequestSync部分:
Drive.DriveApi.requestSync(getGoogleApiClient()).setResultCallback(syncCallback);
final private ResultCallback<com.google.android.gms.common.api.Status> syncCallback = new ResultCallback<com.google.android.gms.common.api.Status>() {
@Override
public void onResult(Status status) {
if (!status.getStatus().isSuccess()) {
showMessage(status.toString());
} else {
showMessage("updated");
}
}
};

操作失败,因为应用程序经常尝试操作。根据官方DriveApi docs,
为避免设备和服务器过载,请同步 请求是有限的。在这种情况下,操作将失败 DRIVE_RATE_LIMIT_EXCEEDED状态,表示已同步 发生在最近,所以不需要另一个同步。该 在足够的退避后重新尝试时,操作将成功 持续时间。
