thats a problem, the measurement of progress...
because apk files size is different, if i will install apk with 5mb file size it will took 3-6 seconds then the "success" will appear on my cmd window on my form, if will install apk with 50mb size maybe it will took a a minute or two,

thats what i want to know,
so you think sir the other apk installer with progressbar, where they get the exact value of progress?
