android 4.0 以上平台选择图片报错Attempted to access a cursor after it has been closed.

Caused by: android.database.StaleDataException: Attempted to access a cursor after it has been closed.

选择图片后 onActivityResult中的代码如下：

 Uri uri = data.getData();
                if (uri != null)
                {
                    mFilePath = new URIUtils().getPathFromUri(uri);
                }

解决办法如注释中的所示。 4.0以上平台会自动关闭cursor

protected String getPath(Uri uri)
    {
        String filePath = "";

        String[] projection = {MediaColumns.DATA };
        Cursor cursor = managedQuery(uri,
            projection,
            null,
            null,
            null);

        if (cursor != null)
        {
            int columnIndex = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
            cursor.moveToFirst();
            filePath = cursor.getString(columnIndex);
            try
            {
                //4.0以上的版本会自动关闭 (4.0--14;; 4.0.3--15)
                if(Integer.parseInt(Build.VERSION.SDK) < 14)
                {
                    cursor.close();
                }
            }catch(Exception e)
            {
                Log.error(TAG, "error:" + e);
            }
        }

        return filePath;
    }
