Play Games Snapshot Konfliktlösung gibt Konflikt

Question

ich den folgenden Code haben:

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(); 
    } 
} 

Allerdings hält dieser Code in der while-Schleife stecken zu bleiben. result behält den Status STATUS_SNAPSHOT_CONFLICT. Irgendwelche Ideen, warum das nicht gelöst wird?

Je nachdem, wie viele Commits zwischen den beiden Versionen stattgefunden haben, müssen Sie möglicherweise mehrere Konflikte in dieser Schleife beheben. Es sollte schließlich stoppen :) Das könnte aber lange dauern.

// Some large number to be defensive against an infinite loop. 
static final int MAX_SNAPSHOT_RESOLVE_RETRIES = 100; 

Snapshots.OpenSnapshotResult result; 
result = Games.Snapshots.open(googleApiClient, "save", true).await(); 

Snapshot snapshot = processSnapshotOpenResult(result, int retryCount); 


Snapshot processSnapshotOpenResult(Snapshots.OpenSnapshotResult result, int retryCount) { 
    Snapshot mResolvedSnapshot = null; 
    retryCount++; 

    int status = result.getStatus().getStatusCode(); 
    Log.i(TAG, "Save Result status: " + status); 

    if (status == GamesStatusCodes.STATUS_OK) { 
     return result.getSnapshot(); 
    } else if (status == GamesStatusCodes.STATUS_SNAPSHOT_CONTENTS_UNAVAILABLE) { 
     return result.getSnapshot(); 
    } else if (status == GamesStatusCodes.STATUS_SNAPSHOT_CONFLICT) { 
     Snapshot snapshot = result.getSnapshot(); 
     Snapshot conflictSnapshot = result.getConflictingSnapshot(); 

     // Resolve between conflicts by selecting the newest of the conflicting snapshots. 
     mResolvedSnapshot = snapshot; 

     if (snapshot.getMetadata().getLastModifiedTimestamp() < 
       conflictSnapshot.getMetadata().getLastModifiedTimestamp()) { 
      mResolvedSnapshot = conflictSnapshot; 
     } 

     Snapshots.OpenSnapshotResult resolveResult = Games.Snapshots.resolveConflict(
       mGoogleApiClient, result.getConflictId(), mResolvedSnapshot).await(); 

     if (retryCount < MAX_SNAPSHOT_RESOLVE_RETRIES) { 
      // Recursively attempt again 
      return processSnapshotOpenResult(resolveResult, retryCount); 
     } else { 
      // Failed, log error and show Toast to the user 
      String message = "Could not resolve snapshot conflicts"; 
      Log.e(TAG, message); 
      Toast.makeText(getBaseContext(), message, Toast.LENGTH_LONG).show(); 
     } 

    } 

    // Fail, return null. 
    return null; 
}

Es ist ein Fehler in Google Play-Dienste App offenbar, die mehrere Fixes muss. Bitte beachten Sie diese Diskussion, wo Google beteiligt ist: GitHub discussion and fix info
