I feel like providing more feedback because this particular error has held me busy the last few days.
Deleting the existing project’s intermediate folder and exporting again did not help.
I am running the latest TADP version with all the Tools installed.
I have my apk signed (or at least I think I have it signed).
I noticed there is a difference between our logs: I have “failed with args” in front of the path to ant. Does that mean something specific? (I read it had something to do with a non signed apk but mine is signed)
Also this error occurred randomly, I belive, as my app was working just fine with being exported to android ETC1 then suddenly without any Blueprint changes it broke.
EDIT: The error stopped after I doubled the “/” in the path to my .keystore. The first time I did that had no effect. Managed to upload two apk’s on GooglePlay.
