Sure but isn't NBAndroid capable of managing the targets and installing new images and such?
I tried to play around with sdkmanager and avd for nearly a day and well, it wasn't that easy, let alone the fact that you need to configure the avd to point to the correct system images when you have a custom avd location and all that fuzz.
Plus that stupid text truncating does not help, you can use --verbose but yeah parsing isn't that easy.
It also feels like doing what has been done three times already. In addition to that there seems to be a sdkmanager.jar at least for the old sdk version before the new tool came, maybe we can directly call that?
Honestly the best would be an android studio exporter I think because we have many things to consider otherwise, let alone debugging and all that stuff.
