1. I start calabash-android console
2. Enter:
   ENV["ADB_DEVICE_ARG"] = "4df1b1021e2b6f4f"
   path1 = File.expand_path("rotate.apk")
   @@App1 = Calabash::Android::Operations::Device.new(
   self, ENV["ADB_DEVICE_ARG"], "45678", path1, test_server_path(path1), 7102)
3. @@App1.start_test_server_in_background

Actual result:
nil But the app does not start

Expected result:
I did the same with other applications and it works
