Reverse Engineering .apk file (or) Getting Java source code from .apk by extracting

Hi friends,

Today we are going to see how the .apk can be reverse engineered to see the original source code

Procedure

1. Get the .apk file (Here I'm taking example apk called psr.apk)
2. Rename the extention from psr.apk to psr.zip file
3. Extract the psr.zip file
4. It will create folder named "psr" and contents will be inside that
5. Download the tool "dex2jar" from the official link
• https://dex2jar.googlecode.com/files/dex2jar-0.0.9.15.zip
6. Extract the downloaded "dex2jar" zip
7. Navigate to the "dex2jar" extracted directory
8. Execute the following command
• ./d2j-dex2jar.sh psr/classes.dex
9. Now it will generate classes-dex2jar.jar file
10. Extract the jar file, it will create "classes-dex2jar" folder
11. Now, open you "intelliJ IDEA"
• Install "Java Decompiler IntelliJ Plugin" in "intelliJ IDEA"
• In IDE, click "File->Open"
• Select the "classes-dex2jar" folder path
12. Now, click on any of the .class file, then you should be able to see the original java source code of it

Isn't it awesome guys :)

We can install in two ways

1. Using PPA
2. Manual Installation

PPA installation

• Open terminal from "Applications" or press key combination "Ctrl+Alt+T"
• Type the following commands in sequence
• $ sudo apt-add-repository ppa:webupd8team/java
• $ sudo apt-get update
• To install latest JDK 8, type the following command
• $ sudo apt-get install oracle-java8-installer
• To install latest JDK 7, type the following command
• $ sudo apt-get install oracle-java7-installer
• Once the download complete, it will ask for agree for terms and conditions
• Click on "OK" to complete the installation

Manual Installation

• Download the Oracle JDK from the following official link
• http://www.oracle.com/technetwork/java/javase/downloads/index.html
• Extract the downloaded zip (Example "jdk-1.8.0.25.tar.gz")
• It will create a folder with name "jdk-1.8.0.25"
• Create a folder "java-8-oracle" under "/usr/lib/jvm" folder
• $ sudo mkdir -p /usr/lib/jvm/java-8-oracle
• Move the folder contents to /usr/lib/jvm/java-8-oracle
• $ mv jdk-1.8.0.25/* -rf /usr/lib/jvm/java-8-oracle/

Configure the java executables

Configuration can only be done if more than one JDK is installed.

To configure java execute the following command

$ sudo update-alternatives --config java

Example output if Java 7 and Java 8 installed
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                     Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-7-oracle/jre/bin/java   2         auto mode

* 2            /usr/lib/jvm/java-8-oracle/jre/bin/java   1         manual mode

Similar way you can do for javac, javaws and other executables

Configure javac

$ sudo update-alternatives --config javac

Configure javaws

$ sudo update-alternatives --config javaws

Happy java coding guys :)

Change IP Address and DNS from static to DHCP and vice versa in Windows Command Line Dynamically using Batch file script

Hi friends,

I was frequently changing my system network from static to dynamic.

I was fed-up with the manual changes by entering the static IP address and changing it to dynamic.

I though of creating a batch file, which requests user to select options and proceed further.

 

I found something on Internet, just modified it for my purpose and thought of sharing with you all.

 

• Check your network name
• cmd> netsh interface show interface
• It will list all the network interfaces connected to your system
• Select the network which you want to change the settings
• Modify the below code with appropriate network name, IP address, subnet, gateway and DNS server

@echo off

set NETWORK="Local Area Connection"
set IP=10.9.40.95
set SUBNET=255.255.255.0
set GATEWAY=10.9.40.47
set DNSSERVER=192.168.178.1

echo Choose:
echo [S] Set Static IP
echo [D] Set DHCP
echo.

:choice
SET /P C=[S,D]?
for %%? in (S) do if /I "%C%"=="%%?" goto S
for %%? in (D) do if /I "%C%"=="%%?" goto D
goto choice

:S
@echo off
echo "Setting Static IP Address, Subnet Mask and DNS Server"
netsh interface ip set address %NETWORK% static %IP% %SUBNET% %GATEWAY% 1
netsh interface ip set dnsservers %NETWORK% static %DNSSERVER% primary
netsh interface ip show config
pause
goto end

:D
@echo off
echo "Resetting IP Address, Subnet Mask and DNS server For DHCP"
netsh interface ip set address name=%NETWORK% dhcp
netsh interface ip set dns %NETWORK% dhcp
ipconfig /renew

echo "New IP Address, Subnet Mast and DNS Server for %computername%:"
netsh interface ip show config
pause
goto end

:end

Now enjoy the feature of changing IP address with 3 clicks

Windows 8.1 Pro Upgrade Keyboard Layout, Keys Mismatch Problem Resolution

Hi all,

I have upgraded my sister’s laptop from Windows 8 to Windows 8.1

I know that, it takes lot of time to download and install. After the whole night download and installation is completed.

But she has come up with an issue saying that, keyboard keys are not displaying correct values.

Problem

Keyboard Layout Adjustment

Resolution

• I have understood that it’s a layout problem.
• Default layout is English (UK). I have changed that to English (India).
• And downloaded the English (US) language pack also.
• For testing your keyboard layout in the live view, you can open “On-Screen Keyboard”
• When you change the layout, the “On-Screen Keyboard” layout gets changed automatically.
• By this way, we can see our keyboard live layout.

I hope someone who think that, it’s a problem can resolve the issue using the above procedure.

Solution to get rid of Vodafone Live Flash (Pop Up) Messages

Hi all,

I have recently purchased the Vodafone SIM.

After a month of usage and paying my bill, I was getting some pop-up message, asking for confirmation to receive some live updates from various categories.

The message also says that, it will cost some 10 rupees. I know that, its simply waste information.

But per day, I was getting more than 25 messages, which made me think eager to stop this irritating messages.

 

I searched in Google and found the following information.

1. Go to “Vodafone Services”
2. Click on “FLASH!!”
3. Click on “Deactivate”
4. It should show a pop-up message “FLASH OFF”

 

If any further message comes just ignore/cancel it

I think, it worked for me. Let me see for one more day. If still the problem exists, then I will update this blog.

 

I hope, if anyone facing this issue, they can get rid with this solution.
