Android /system/framework/*.jar files

I did ls -al /system/framework/ on my Android 5.0.1 phone via adb shell

I noticed about 95% of the .jar files there were 309 bytes. After pulling one such file using adb pull and unzipping them showed the .jar file only contained /META-INF/MANIFEST.MF

Where is the actual dex code of these jar files. ?

P.S. My phone is not rooted.

Solution

  • From Lollipop, due to ART, the framework files are in /system/framework/arm/boot.oat file.

    Use 'java -jar oat2dex.jar boot boot.oat' and you will get a dex folder containing framework.dex and framework-classes2.dex.
