setup_jdb.md

start bluestack or emulator install app on it start the app

connect adb to emulator

$ adb connect localhost:5555

get 'pid' of your app .Dont forget to run it first in emulator

$ adb shell ps

confirm the pid

$ adb jdwp

forward a local socket to PID 290 to start debugging.

$ adb forward tcp:8700 jdwp:290

This tells adb to forward a local socket on port 8700 to the app with PID 290 that’s hosting a JDWP transport.

start debugging the simple test app

$ jdb -attach localhost:8700 -sourcepath /path/to/test/app/src.

on error try this instead of above command

$ "C:\Program Files\Java\jdk1.8.0_45\bin\jdb" -sourcepath ./app/src -connect com.sun.jdi.SocketAttach:hostname=localhost,port=8700

If all goes well, you’ll have a jdb prompt in which you can start adding breakpoints.

Set uncaught java.lang.Throwable
Set deferred uncaught java.lang.Throwable
