These are the steps I followed -
>Calabash-android console file.apk
irb(main):003:0>reinstall_apps
irb(main):004:0>start_test_server_in_background
nil
There is no error but my app is not launching. All I can see is a black screen like app is about to launch but its not. I tried replicating it on another test project but its working fine.
If you are using any custom activity, use environment variable MAIN_ACTIVITY
while using run command.
calabash-android console file.apk MAIN_ACTIVITY="com.example.youractivity"
