There are a lot of applications for Android and adding new one every
day. But Android development system is open and you should know your
apk file can be open by anyone.

So how can i do that  two softwares?

Firstly you should have a Android APK file.

1- Dex2jar software ( http://code.google.com/p/dex2jar/ ) is making a
android apk file to jar file.
After installation type this command in CMD.exe

D:\Android\dex2jar-0.0.9.8>dex2jar
“UCBrowser_V8.0.5.118_Android_pf145_(Build12010514).apk”

UCBrowser apk file converted to jar file.

2- Java decompiler software can converts jar file to pure java  code.
You can download in http://java.decompiler.free.fr/?q=jdgui address.
When opened any jar file in java decompiler you can see likely this
screen.

If you are developing with LCL-CustomDrawn-Android then you are
protected, because the actual source code is native Pascal which
cannot be decompiled and not Java which is easily decompilable.
