My path is different (C:\Users\kpmaster\AppData\Local\Android\android-sdk\tools\), but anyway you are right, the zipalign.exe has disappeared from there. Probably some andoird-sdk update has removed the files because i did not found it.
Thanks for the file, after place it in the tools folder the compile works well.
I recently updated Android SDK and zipalign is located in install_path\android-sdk\build-tools\19.1.0. It works fine with B4A 3.82, but it may be because I changed the path to the Android-L version of android.jar. Maybe B4A is set to use the new path when you use the Android-L version of android.jar, and the old path when using another one?
I don't know what to say. Recently I've updated to my android-sdk, but not downloading the L version. On my pc now I have versions 8, 10, 14, 16, and 19. I suppose I have to change the path of android.jar basing on where I want my apps should be used.
By the way, the zipalign.exe was disappeared from my pc, but now that sorex gave me the file, I'm able again to compile my projects.
