Are you using binary or source for your engine? Are you able to package anything, for instance the Tappy Chicken project from the Learn tab of the launcher? Can you try packaging Tappy for development and ETC1 and posting the output logs here regardless of whether it succeeds or fails?
Are you using the native Android SDK or the recommended TADP tools from the documentation?
I did not manage to build a blank project or Tappy Chicken if I chose Shipping and for distribution, but if you choose to development, the building well.
I can not to build etk1, all and other.
In version 4.6 I can build projects even with the Shipping and for distribution.
I use a binary engine.
I use TADP this location: “D:\UnrealEngine4\Epic Games\4.8\Engine\Extras\Android\tadp-2.0r8-windows”
