Most logging frameworks can be extended by writing some glue code that translates the logs from one framework to another.
Bugfender has advanced logging methods that are suitable for this integration:
On iOS, check log(lineNumber:method:file:level:tag:message:) method (see full reference).
On Android, check the log() method (see full reference).
