When attempting to launch your mobile app on Android the below error is observed:
Login failure: com.ca.mas.foundation.MASException: Unable to post to register_device: Unable to resolve host "<MAG_HOSTNAME>": No address associated with hostname
Ensure the hostname for the MAG server is accessible. Typically, this caused by a bad hostname/ IP address or a failed network connection.
In the case of emulated devices where name resolution is done from the host system's hosts file, it may be necessary to push an updated file directly to the device.
Change to the sdk/tools folder:
1) emulator -avd <avdname> -writable-system
2) ./adb root
3) ./adb remount
4) ./adb push <local>/hosts /etc/hosts
