我有以下代码:
Snapshots.OpenSnapshotResult result;
result = Games.Snapshots.open(googleApiClient, "save", true).await();
while (result == null || !result.getStatus().isSuccess()) {
Log.d("Snapshot", "Open snapshot");
if (result.getStatus().getStatusCode() == GamesStatusCodes.STATUS_SNAPSHOT_CONFLICT) {
Snapshot snapshot = result.getSnapshot();
Snapshot conflictSnapshot = result.getConflictingSnapshot();
// Resolve between conflicts by selecting the newest of the conflicting snapshots.
Snapshot mResolvedSnapshot = snapshot;
if (snapshot.getMetadata().getLastModifiedTimestamp() <
conflictSnapshot.getMetadata().getLastModifiedTimestamp()) {
mResolvedSnapshot = conflictSnapshot;
}
result = Games.Snapshots.resolveConflict(
googleApiClient, result.getConflictId(), mResolvedSnapshot).await();
}
}
但是,这段代码一直卡在 while 循环中。
result
保持状态
STATUS_SNAPSHOT_CONFLICT
.关于为什么这没有得到解决的任何想法?
请您参考如下方法:
根据两个版本之间发生的提交次数,您可能需要解决该循环中的多个冲突。应该最终停止 :) 这可能需要很长时间。
