java.lang.IllegalStateException：宏達Android 6.0棉花糖崩潰 - 谷歌播放快照

Question

我有一個應用程序發佈，適用於從Android 4.X到7.X的各種手機。但有一個設備，HTC One M9（6.0棉花糖）和應用程序每次崩潰。當主菜單加載並且應用程序嘗試連接到Google Play遊戲服務時，它總是會發生。說實話，我沒有得到錯誤日誌。這就是我得到：

    ... 4 more 

而且，兩條線在日誌中提到我的MainActivity.java這些方法中（在這裏「Snapshots.OpenSnapshotResult打開」）：

private void savedGamesUpdate() { 
     final String snapshotName = makeSnapshotName(APP_STATE_KEY); 
     final boolean createIfMissing = true; 

     // Use the data from the EditText as the new Snapshot data. 
     final byte[] data = mSaveGameData; 

     AsyncTask<Void, Void, Boolean> updateTask = new AsyncTask<Void, Void, Boolean>() { 


      @Override 
      protected Boolean doInBackground(Void... params) { 
       Snapshots.OpenSnapshotResult open = Games.Snapshots.open(
         mGoogleApiClient, snapshotName, createIfMissing).await(); 

       if (!open.getStatus().isSuccess()) { 
        return false; 
       } 

       Bitmap coverImage = BitmapFactory.decodeResource(MainActivity.this.getResources(), 
         R.mipmap.autosave); 
       String desc = "Autosave "+android.os.Build.MODEL; 
       // Create the change operation 
       SnapshotMetadataChange metadataChange = new SnapshotMetadataChange.Builder() 
         .setCoverImage(coverImage) 
         .setDescription(desc) 
         .build(); 

       // Change data but leave existing metadata 
       Snapshot snapshot = open.getSnapshot(); 
       snapshot.getSnapshotContents().writeBytes(data); 

       Snapshots.CommitSnapshotResult commit = Games.Snapshots.commitAndClose(
         mGoogleApiClient, snapshot, metadataChange).await(); 

       if (!commit.getStatus().isSuccess()) { 
        return false; 
       } 

       // No failures 
       return true; 
      } 

      @Override 
      protected void onPostExecute(Boolean result) { 
       dismissProgressDialog(); 

      } 
     }; 
     updateTask.execute(); 
    } 

這一個：

private String makeSnapshotName(int appStateKey) { 
     if(isAnHTCDevice()){ 
      return "Autosave HTC"; 
     }else{ 
      if(android.os.Build.MODEL != null){ 
       return "Autosave"+android.os.Build.MODEL; 
      }else{ 
       return "Autosave"; 
      } 
     } 

    } 

    public boolean isAnHTCDevice() 
    { 
     String manufacturer = android.os.Build.MANUFACTURER; 
     if (manufacturer.toLowerCase().contains("htc")) 
      return true; 
     else 
      return false; 
    } 

任何人都知道這可能是什麼原因？

RTFM。如文檔中所述，[快照。打開]（https://developers.google.com/android/reference/com/google/android/gms/games/snapshot/Snapshots.html#open(com.google.android.gms.common.api.GoogleApiClient，java.lang.String，布爾值））

要打開的快照文件的名稱。必須介於1到100個非URL保留字符（a-z，A-Z，0-9或符號「 - 」，「。」，「_」或「〜」）。

所以，修改makeSnapshotName方法來生成一個有效的文件名。
