Android apk anti-compilation get Java source code (v)

APK software Anti-compilation go ads

Specific steps:

1. Download apktool

:https://code.google.com/p/android-apktool/downloads/list

2. Decompile the APK with Apktool. On the command line, enter the following command: Apktool.bat d-f aaa.apk (apk Path) anti-compilation apk file

3. Start modifying the XML layout file

First, let's go to the anti-compiled folder, take my example

Enter the C:\apk\com.youmi.android.sample\res\layout directory

Open Activity_ad.xml with Notepad (note: Different program ads are located in the same file, you can view the other files, usually in the Res\layout directory in the XML file. ）

You can see the following section of code

1 <LinearLayout2         Android:id= "@+id/adlayout"3 Android:layout_width= "Fill_parent"4 Android:layout_height= "Wrap_content"5 Android:layout_alignparentbottom= "true"6 android:gravity= "Center_horizontal"7 android:orientation= "Horizontal"8         >

This code is used to display the ads we can change to

1 <LinearLayout2         Android:id= "@+id/adlayout"3 Android:layout_width= "Fill_parent"4 Android:layout_height= "Wrap_content"5 Android:layout_alignparentbottom= "true"6 android:gravity= "Center_horizontal"7 android:orientation= "Horizontal"8 android:visibility= "Gone"9         >

So the ads are hidden.

4. Compile the modified code by Apktool apk, enter Apktool.bat b aaa (you compiled the folder)

5. Finally, remember to sign the new apk.
