Improve version 0.1.4

[JohnTroony]

Change log:

1) Add colors for different program message output

green="\033[32m"
blue="\033[34m"
red="\033[0;31m"
yellow="\033[33m"
normal="\033[0m"

• green is used for messages containing program activity status
• blue is for finished activities and program info
• red is for error messages or critical messages
• yellow is for the intro banner and menus

  2) Remove redundant error checking code

if [ $rc != 0 ]; then
  echo "[!] Failed to decompile original APK file"
  cleanup
  exit $rc
fi

The above error checking code has been replaced by an exception_handler function below;

function exception_handler {
  if [ $1 != 0 ]; then
    echo -e "$red $2 $normal"
    cleanup
    exit $1
  fi
}

It take the error status code ($rc) and the error message, as inputs.

3) Add function to check if required packages/libs have been installed.

function checkLibs {
if [ $(dpkg-query -W -f='${Status}' $1 2>/dev/null | grep -c "ok installed") -eq 0 ];
then
  apt-get install "$1";
else
  echo -e "$blue $1 installed $normal"
fi
}

If a required package is not available, it's going to be installed.

GOTCHA:

Here I've assumed the user is on a Debian based Linux distro - (Kali).

4) Generate Metasploit RC file

After creating the backdoor APK file, the option used for payload generation is later used for creating a Metasploit rc file. This automates the process of setting up the required listener for the backdoor APK.

To execute the file:

run msfconsole -r backdoorApk.rc.

@JohnTroony Thanks for the work here. I'll make some time to review.

No problem @dana-at-cp

[dana-at-cp]

@JohnTroony FYI. I really like the Metasploit RC file generation idea.

[JohnTroony]

Nice! @danta-at-cp

@JohnTroony Thanks again for this pull request. I'm incorporating your Metasploit resource script suggestion in the next release. I'll give you credit for the suggestion in the "AUTHORS" file if that is alright with you.

This pull request will be closed.

No problem! Thank you for your time to review the PR.
