NullPointerException in LocalCollection.updateByRemoteName



  • Hi,

    I get said NullPointerException (logcat at the bottom) and davDroid consequently crashes.

    I think it might be a missing null check on localResource in LocalCollection.updateByRemoteName as:

     public T findByRemoteName(...){
      ...
      line 139:   return null;
      ...
    }
    ...
    public updateByRemoteName(...) {
        line 166: T localResource = findByRemoteName(remoteResource.getName(), false); 
        ...
        line 169: localResource.getLocalID()
        ...
    }
    

    seems to be a possible path.

    The relevant logcat extract below (seems to be all there is):

    I/ActivityManager( 1644): Start proc at.bitfire.davdroid:sync for service at.bitfire.davdroid/.syncadapter.CalendarsSyncAdapterService: pid=9781 uid=10089 gids={3003, 1028}

    I/ActivityManager( 1644): Process at.bitfire.davdroid:sync (pid 9781) has died.
    

    My setup is an Android Device (4.1.2) syncing with an owncloud instance.

    I have already added that check today. I just don't understand how there can be null objects…
