Summary0007759: qtart crash when the exchange as a big tos
DescriptionThis error was seen in the debug logs.

There is one big exchange Tos (format html) which is 600k. After removing scripts and css it was reduced to 20k and then adding the exchange to the wallet worked.

Although, it may be the case that the second time another format was provided by the exchange.

This is not an issue with wallet-core or qtart, but rather an issue with Android IPC. There's a limit of data that can be exchanged between the app and the service at once, and there's nothing we can do to increase the limit other than simply refactoring the app to not use a service, and thus not do IPC. This issue is known already. Torsten said he would refactor the app to not use a service.

The transfer amount should now be only limited by RAM available to our JVM.
