The compilation process is succesfull, download APK to my computer, gives me an APK that is not readable in the Play Store and not readable by AppToMarket decompile.
It is a an app that I have been working on for 2 weekes. Till the 24th APK’s made with Appybuilder were oke. The first error appeared the 24th of december. After a few tries and another browser, it made a working APK again.
But since yesterday, the 26th of december, it is not possible anymore. It makes the APK, but it is not an usefull APK.
