Unable to get DEX from OAT of Android N image
xsveda opened this issue · 7 comments
I pulled out a boot-framework.oat from emulator with Android N image
adb pull system/framework/arm/boot-framework.oat
but getting DEX from it fails:
java -jar oat2dex/oat2dex.jar boot boot-framework.oat
Invalid dex magic
java.io.EOFException

Is there anything I'm mussing or is it just an unsupported OAT format in Android N?
Unsupported, I believe. I think they just moved them out of boot.oat so it should be easy, right?
Any plan to support new OAT format in Android N? Or is it possible to get DEX any other way? I'll be grateful for any hint.
The commit 227f79c should be able to extract dex for android N.
(Tested with emulator, only an error when deodex apache-xml.dex)
I did not upload last snapshot build because N is not formal release yet.
To have a try, just pull the latest code and build with command in the readme.
For deodex Android N you can use my tool Batch Apktool, it uses latest oat2dex

@bursoft-git Nice tool, but I do have a request
I'm not sure how plugins work in your tool, so it could be something easy, but after deodexing my system apps, I find that some signatures mismatch. It could be my fault, but does the tool sign all apks regardless if they are odexed or not? and if does not, can it?
@aaahh
As far as I know, in 90% of cases signing system apps is not required
But if you want you can sign the necessary files manually (using the [4] option)
