我从 sqllite 收到一个错误，上面写着这样的内容。现在我检查了日志，它似乎总是随机出现。它永远不会在相同的功能或日志行之后。这是错误：

这是来自 DetectedActivity API 的 onReceive 广播：

rawData += ")";

这就是我所说的活动：
ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(
mGoogleApiClient,
Constants.DETECTION_INTERVAL_IN_MILLISECONDS,
getActivityDetectionPendingIntent()
).setResultCallback(this);
现在我检查了一下，我没有在我的数据库中添加任何位置（我使用 REALM.io 库作为我的数据库）。所以这个错误对我来说根本没有意义。有没有其他人遇到过这个？有没有办法来解决这个问题？
PS：我在带有 Android 6 的 Nexus 5 上收到此错误
