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(); 
    } 
} 

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。
