2023 AOSP and AAOS July Meetup: Debugging AOSP using Android Studio - revisited
Переглядів 519
10 місяців томуThis is an update to Chris Simmonds' talk at the May 2022 meetup. This time he talks about a better way to attach to apps running on emulators and physical devices, and how to use JDB for a quick, works-out-of-the-box debugging experience

Great video! Hi sir. Thanks for this great informational video. There is one small issue I am having. I don't see any processes in adb jdwp in Android 14. But it works fine in Android 13. Is there any changes that I maybe missing.
@chrissimmonds 2 місяці тому
Yes, this changed in AOSP 14. Previously, on userdebug and eng builds all apps were created with a JDWP thread by default. Now you have to explicitly enable it by setting property persist.debug.dalvik.vm.jdwp.enabled to 1, e.g. by typing: $ adb shell setprop persist.debug.dalvik.vm.jdwp.enabled 1 $ adb reboot

@@chrissimmonds hi.. thanks for the update. It worked fine. Although is there a way to get more logs in jdb? Like more information about how it reached to the breakpoint

As AOSP has lots of C/C++ code, how would one debug those? I assume using JDB for debugging C/C++ code won't work?

Great question: we covered this in the July 2022 meetup talk "Debugging native platform code using LLDB". Slides: 2net.co.uk/slides/aosp-aaos-meetup/2022-july-native-debug.pdf. Video: ukposts.info/have/v-deo/gJOmd3pupY6Wwn0.html
