APK Toolkit v1.2 now includes the ability to remove ads via regex search & replace
Included regex has been gathered from various sources and changed and optimised for speed and efficiency

Notes for creating new regex
  • Regex are checked on a complete smali text file NOT line by line
  • Decompiled smali code line endings are \r\n (CR = Carriage Return, LF = Line Feed) so you can use these if you want to match line endings
  • using $1 in the replace regex will replace the 1st match group, $2 will be the 2nd etc.
  • Apps / Games can have 10's of thousands of decompiled smali code files so avoid using .* without the 'lazy' quantifier (.*?) because regex are not checked line by line but as a whole file. Complex regex using 'any characters' 'greedy' quantifiers .* might be VERY slow due to the amount of files being checked and will probably replace multiple functions at once so avoid 'any character' 'greedy' matches
  • Regex are run only on your selected 'Enabled Checked' list. You can run Search & replace on any number of your 'List' at once but running them all at once might be slow depending on the number of smali files or possibly replace the wrong piece of smali code causing an accidental mobile app crash. For ad removal, you may have to experiment with the different included regex list for different types of ads / banners
  • You can build and test your regex via the online site Regex101 to make sure your regex is valid and only replacing the code you want removed / replaced

If anyone wants to share any regex you have created then please make sure that they are optimised using the notes I listed above and tested on an apk containing your new regex match and the apk re-compiles without errors

If anyone has any problems with any regex you have created and want help then please just ask

@0xd00d getting error like this

[15:26:08] Exception in thread "main" brut.androlib.AndrolibException: brut.directory.DirectoryException: java.util.zip.ZipException: Invalid CEN header (invalid zip64 extra data field size) at brut.androlib.ApkDecoder.hasResources(ApkDecoder.java:294) at brut. A


there is a fix for this if you update your code

"java_exe" -jar -Duser.language=en -Dfile.encoding=UTF8 -Djdk.util.zip.disableZip64ExtraFieldValidation=true -Djdk.nio.zipfs.allowDotZipEntry=true

i have updated the code in APK easyTool now its working fine

Thanks for the heads up :laugh:

It seems its caused due to the latest change in JDK 11.0.20

core-libs/java.util.jar
Improved ZIP64 Extra Field Validation(JDK-8302483)
java.util.zip.ZipFile has been updated to provide additional validation of ZIP64 extra fields when opening a ZIP file. This validation may be disabled by setting the system property jdk.util.zip.disableZip64ExtraFieldValidation to true

i'll add the workaround hopefully on the weekend :tumbsup:

Can you please supply a download link or name for an affected apk that shows this error? So I can test the fix is now working?
