To Reproduce

• [x] I have tested this issue on the latest Loki release and it still reproduces

Steps to reproduce:

1. Clone Loki latest react-native example https://github.com/oblador/loki/tree/master/examples/react-native
2. Remove ios simulator to run only on Android from your package.json as follows

 "loki": {
    "configurations": {
-      "ios.iphone7": {
-        "target": "ios.simulator"
-      },
      "android.pixel": {
        "target": "android.emulator"
      }
    }
  }

Expected behavior

• I expected the default React Native example to run successfully on Android Pixel 2

Environment (please complete the following information):

• Loki: 0.28.1(latest)
• React Native: 0.63.4
• Node: 14.15.4
• Device: Pixel_2_API_30
• OS: Windows 10, 64 bits, 16 GB RAM. Intel i7

Thanks!
