APK file :study : Dump/Dex2jar/Modify

Reference:
+http://www.androidguys.com/2010/12/23/modify-apk-files/

Dump the apk file: please refer to other post before.

Zip:

+ change the aaa.apk to aaa.zip, and unzip it.

after unzip it, the following is the struct

The in the folder under res\, the res\layout resource file(.xml) is the same as build. Because I just rename the *.apk file *.zip,and can unzip it. so I use winRAR to open *.apk directly, and saw the same struct as below.

classes.dex:

There is a *.dex here, after google it. I found the dex2jar project

https://code.google.com/p/dex2jar/wiki/ModifyApkWithDexTool

the example is so cool! that modify the apk file.

I follow the step to compare it to the original project in the Eclipse.

I also include the bbb.jar file which generate by dex2jar.exe into the Eclipse,

as you can see when you access it, it should shows the bytecode.

Java : byteCode:

+ wiki (has example)

*.java --> *.class (byteCode)

C code:

*.o

*.so

Sample code of Digit Detector

Sorry, need more time to review before upload to share to all of you.

Digit Detector in Google Play

This is my first sample program uploaded to Google play to share all of you.
The functionality of this program is try to detect the digit dynamically. kindly try it and provide your precious comments if possible. thanks.

[Background]
1.The program is implemented by using OpenCV.
2.Base on the face detector sample code in OpenCV
3.Since pixel process cost time, need calling into JNI interface to run the algorim in C/C++ code.

[How to run]
Step 1: just download it from Google play.
Step 2: move device until the digit inside middle Rect, then the result will show in right side.

[Try it]
@Google Play
