I don't think so because it's a server side error and only developer can resolve this problem. You just need to report as a bug.

Answer 3

Can you share this app link so I can check from my side?

Answer 4

Last 2 lines are the internal process of LinkedList class. To know more about this you have to open this class in any java decompiler

This exception generally comes when you modify list while iterating the list.

If code is written by you then you have to handle this exception. I have shared 2 links you can see there how to solve this..

Answer 5

I ᴀᴍ "Tɪᴍᴇ" just by opening the app? Also what are the symbols after “at” on the last 2 lines?

Answer 6

I ᴀᴍ "Tɪᴍᴇ" I updated the code to provide a better explanation to my problem

Answer 7

I ᴀᴍ "Tɪᴍᴇ" but I didn’t write or modify any code

Answer 8

Then you need to tell this error to app developer.

Answer 9

I ᴀᴍ "Tɪᴍᴇ" since the app used to work, could I have Inadvertently done something to cause the error?

Answer 10

I ᴀᴍ "Tɪᴍᴇ" how can it be server side when works the same in airplane mode as it does with wifi on. And it accesses my tablet’s files.

Answer 11

I ᴀᴍ "Tɪᴍᴇ" It isn’t in the play store anymore. But it is called “MT Manager”.
