title: Android auto backup error
body: <p>I'm trying to implement android auto backup (Android 6.0) but it doesn't work.</p>
  
  <p>I get the same error with </p>
  
  <pre><code>10-28 22:58:06.980 600-5578/? I/PFTBT: Initiating full-data transport backup of com.myapp.package
  10-28 22:58:06.981 7891-14015/? I/GmsBackupTransport: Attempt to do full backup on com.myapp.package

  10-28 22:58:06.982 600-610/? D/BackupManagerService: Done with full transport backup.
  </code></pre>
  
  <p>I tried enable</p>
  
  <pre><code>adb shell setprop log.tag.BackupXmlParserLogging VERBOSE
  </code></pre>
  
  <p>and</p>
  
  <pre><code>adb shell setprop log.tag.GmsBackupTransport VERBOSE
  </code></pre>
  
  <p>but I don't see any more information in the logcat. After turning backup off and on I instead get this error. How to resolve it?</p>
