vdexExtractor cannot use in Android 10，can you help me？

[tjzhou23]

Hello, thank you very much for developing such a great tool, vdexExtractor. However, I recently discovered that , I am using "adb pull /system/framework/*.dex", and then using vdexExtractor can't get the dex file on Android 10. The boot-framework.vdex are small on Android 10, but the boot-framework.oat and boot-framework.art files are big, it is strange. In addition, I cannot use jadx to open the /system/framework/framework.jar file directly. The framework.jar contains 4 dex files. Decompressing the framework.jar to export the dex, I also cannot use jadx to view the dex source code.it makes me upset. can you help me solve this problem?

May be there's no dex file in vdex file ? Android 9 introduced uncompressed dex, and for Android 10, most of the boot dex files are not compressed in the jar files. For such kind of jars, dex2oat will not re-write dex file into vdex files.

in my case, the same problem. android 8, the vdex_extractor operates well. but Android 9~10 this vdex_extracotr is not doing well!

always this log print ERROR] Unsupported Vdex version [WARNING] Invalid Vdex header - skipping './Pixel/framework/arm64/boot-ims-common.oat'
