How to exclude the android libraries when decompiling?

[Qidan He]

I found every time the android library was also included when decompiling, which wastes a lot of time. I wonder if there is a way to exclude the android libs.

Thanks.

Hello,

It should not be decompiling the libraries, they are simply included so that Soot can resolve references to them. The included libraries can be modified using the -a option for dare-launcher (which is called by the dare script).

Hi:

First thanks for your reply, but I have observed android library classes are being decompiled. 

Maybe the launch arguments need to be tuned and I will appreciate it if anyone tells me what should I do to avoid this. 

My command line argument for dare launcher is 

./dare -c -e -d output/ target.apk

After retargeting is finished then I got output like this:

 

Decompiling android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat... 
Analyzing output/optimized-decompiled/target/dava/src/android/support/v4/accessibilityservice/AccessibilityServiceInfoCompat.java... 
Generating output/optimized-decompiled/target/dava/src/android/support/v4/accessibilityservice/AccessibilityServiceInfoCompat.java... 

Which shows dava is actually decompiling android classes...

After I ran the script for several hours, I got hundreds of decompiled android classes source like

>> find ./ -name *.java

.//accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoIcsImpl.java

.//accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoStubImpl.java

.//accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl.java

.//accessibilityservice/AccessibilityServiceInfoCompat.java

.//accessibilityservice/AccessibilityServiceInfoCompatIcs.java

.//app/ActivityCompat.java

.//app/ActivityCompatHoneycomb.java 

.//app/BackStackRecord$Op.java

.................... 

 

 which obversely consumed a huge amount of time. 

Thanks.

Hello,

This is a support library, which is packaged with the application for backward compatibility. You can find more information about it at http://developer.android.com/tools/extras/support-library.html

Something you could do is launch Dare without the -c option and then launch Soot yourself and include only the classes you want to decompile. Information on Soot is available at http://www.sable.mcgill.ca/soot/

Hi Qidan He

I am facing the same issue, were you able to find a solution to exclude the support packages. I did not get the way to implement the suggestion, suggested by Damien.

Thanks and Regards
