How To

1. Extract batch file and lib folder to C:\apk2java\ (or any folder that doesnt have space in its path)

2. Backup the target app’s apk from phone to PC via ASTRO Browser (check this post for details)

3. Keep the target apk in the root folder where batch file is present

4. Run ‘apk2java.bat target.apk’ in cmd

c:\apk2java>apk2java.bat target.apk

5. Result : java and resource files available in ‘src’

Note: This batch just automates the sequence in which various tools are initiated and does not handle any error events. You will have to go through the cmd verbose to figure out the problem.

Note 2: ‘lib’ folder contains apk-tool files (apk-tool.jar, aapt.exe), jad.exe, 7zip (7za.exe), dex2jar files (all other jars).  If required, update each of those tools by replacing it with latest copy from links mentioned below.

Requirements

• Windows (but can be ported to *NIX)
• JRE 1.6 (Java Runtime Environment)

Tools in lib

• Dex2jar – Converts Android dex format to jar (link)
• JAD – Java Decompiler CLI (link)
• 7Zip – Unarchival  (link)
• apk-tool – Extracts resources from apk (link)
• aapt – Android Asset Packaging Tool (link)
• aapt commands (link)

You can even do more than starting programs with the built-in file management functions like Copy, Rename, Makedir, Delete, End Process, Kill Process and Text to Clipboard. Batchrun batch files can be launched from Explorer or placed in StartUp folder or on the Desktop.

Check how to enable and disable USB devices with batch programming

Features

• Launch files of any filetype and dialup connections
• Internal commands: Run, Copy, Rename, Makedir, Delete, DelTree, End Process, Kill Process, Text to Clipboard
• Wildcard support for Copy, Delete and DelTree
• Makedir nested folder creation
• Drag and Drop between Explorer and Batchrun
• Support for date and time tags
• Command line parameters can be passed to Batchrun script files
• Save batch files directly to Startup and Desktop

Note: If you are using the portable version of BatchRun make sure that you associate ‘*.brs‘ files with this application.

The script will enable the security permissions which will help us to modify certain registry keys, then modifies the required keys and reverts back the permissions.

First create four files as mentioned below.

0.reg

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesUSBSTOR]
"Start"=dword:00000004

1.reg

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesUSBSTOR]
"Start"=dword:00000003

SubInACL

Before proceeding further you need to download SubInACL (Incase if the link doesn’t work, google for ‘SubInACL’ to get the MS download link). This tool helps you to set ACL permissions for the registry keys through command line parameters.

@echo off
cls
regedit /s 0.reg
subinacl.exe /keyreg systemcurrentcontrolsetservicesusbstor /deny=system
subinacl.exe /keyreg systemcurrentcontrolsetservicesusbstor /deny=users
subinacl.exe /keyreg systemcurrentcontrolsetservicesusbstor /deny=administrators
echo.
echo **Disabled**
echo.
//pause

@echo off
cls
subinacl.exe /keyreg systemcurrentcontrolsetservicesusbstor /grant=system
subinacl.exe /keyreg systemcurrentcontrolsetservicesusbstor /grant=users
subinacl.exe /keyreg systemcurrentcontrolsetservicesusbstor /grant=administrators
regedit /s 1.reg
echo.
echo **Enabled**
echo.
//pause

After creating all the above mentioned files, put those in a directory. Make sure you have all the five files in the same directory (i.e 0.reg, 1.reg, enable.bat*, disable.bat* and subinacl.exe).

Now double click the batch file* to see it in action.

Note*:

Uncomment pause command to see the execution status in the command prompt.
