i wanted to finish our environment, so i thought to change the package name in b4a ide. After i did this compiling now takes double time or morge, before 20 seconds. after changing up to 80 seconds. I restartet b4a ide and devices...no changes. running project without this changement of the day before runs fine by 20 seconds.
Did you try Tools> Clean project? After a change like that it would probably be a very good idea. I do that every time I am about to compile my app. It cleans out the cobwebs left over after making changes, especially significant ones. Just a thought.
