Dear All,
I have the server set up to run according to this example
https://www.b4x.com/android/forum/threads/b4x-remote-mongodb-connector-rmdbc.72270/
In B4A, I added the following line to the Manifest file
'CreateResourceFromFile(Macro, Core.NetworkClearText)
SetApplicationAttribute(android:usesCleartextTraffic, "true")
The B4J RMDBCServer application was running permanently on the server, but running the B4A application always gave the following error:
Logger connected to: 8437d8ad
--------- beginning of crash
--------- beginning of system
--------- beginning of main
** Service (httputils2service) Destroy **

Thank Mr. Erel very much
Maybe you right
When the above error occurs on the B4A side, at the same time on the B4J side on the server there is also the following message:
SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#noProviders for further details.
java.lang.RuntimeException: java.lang.RuntimeException: Object should first be initialized (MongoDatabase).
