i want to catch my directory last name "bes" where is <project-dir>/src/com/seri/bes

 #!bin/bash

i use myendpath=${PWD##*/}at this line but variable return "w";

myendpath=ls ../src/com/seri/
me="../bin/$myendpath-debug.apk"
adb uninstall com.seri.$myendpath
adb install $me

Solution

#!bin/sh  
my1=$(ls ../src/com/seri)
my2="../bin/$my1-debug.apk"
adb uninstall com.seri.$my1
adb install $my2
