The let command is in bash but not in the POSIX shell. If a system has /bin/sh symlinked to /bin/bash (like mine does) then this problem does't occur, but when it's symlinked to /bin/dash then it does. The proper solution isn't to change the symlink, but, rather, to fix the first line in the script to specify #!/bin/bash rather than #!/bin/sh. I've been fixing those slowly.

The mk4build script was fixed between 6.4 and now. You should probably be building from master anyway. In fact, I'd appreciate it if you'd give that a try in case you encounter more problems. If you do, it'd be nice to address them before 6.5 is released.

>Now I've several apks in  "Android/Gradle/app/build/outputs/apk/debug/",

Either the universal one or the one that's specifically for your architecture. The universal one can be used for any architecture because it contains all of the architecture-specific ones - which makes it much larger. I think, therefore, that you should be using the architecture-specific one.
