so yes like currently I am working on specially Java Kotlin is also there and the challenges is that like currently I am working on the DeFi so there is a lot of thing like when we are building when we are creating our build and deploy to the devices so that time facing a lot of issue fast boot is not working sometime reboot is not working and the most important thing when it is very difficult to find out the exact issue because here no debugging process so we are using only the logs
