bangcle's Issues

Add 16 KB support for Android 15

Hi, Android 15 is introducing a 16 KB page size development mode and asking new apps to work in this mode, so that future devices can use 16 KB pages. You may want to ensure your obfuscator works in this mode, so that app developers using this software package don't have to update themselves. Thank you!

here is the output

pls add x86

pls add lib x86

Please support x86 processor

Today, lot of android devices and emulators are x86 based processor. It would be great if Bangcle support this processor type.

Thank you for your great tool!

Multidex not supported

If i try to encrypt APK that has multidex, it only encrypts first dex. Game crashes because of that. Can you add support for Multidex?
