1326559 - "mach install" on Android x86 AVD causes a reboot

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: Testing, defect, P1)

Description

[Ethan Glasser-Camp (:glasserc)]

Attachment: logcat.txt from adb logcat during reboot

I was able to get the android emulator started by removing `-enable-kvm` from `android_devices.py` and using `./mach android-emulator --version x86`. However, when I tried to do `./mach install`, the Android emulator rebooted (making it difficult to install or test my build). I'm not really an expert in this area, but from what I can see, the `emulator.log` output doesn't look unusual. The output of `adb logcat` during this process shows a SEGV of `PackageManager`. I have attached this log in case it is of any use.

This works for me: I can 'mach android-emulator --version x86' and then 'mach install' (after building and packaging for x86) and then I can start Firefox on the emulator - no sign of trouble.

I tested on Ubuntu 16.04, with adb 1.0.36.

I was able to reproduce it again on an artifact build of current tip (a9a67c9d3659fcd3dc4f5e5cdf1f889fd918e360). Fedora 25, adb 1.0.36. Sometimes instead of rebooting, I get "Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]" instead.

One thing that I might have done that perhaps makes my situation unique was that I ran "tools/android update sdk" at some point because I saw some message that something was out of date. It spent a lot of time downloading and updating stuff but I didn't really understand what it was doing. Is it maybe possible that I'm running a mixed-version environment or have the wrong SDK version or something? I noticed I wasn't running the right version of the Android build tools (I had 23.0.1 whereas https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Simple_Firefox_for_Android_build says I need 23.0.3), so I updated to 25.0.2, but I can't tell if those are the ones being used or not.

I still have not managed to reproduce this. 

I just ran, on Ubuntu 16.04 with adb "version 1.0.39 Revision 3db08f2c6889-android":

  ./mach build && ./mach package && ./mach android-emulator --version x86 --force-update && ./mach install

and had no problem.

:glasserc -- Do you still have trouble today? If not, can we close this?

I haven't done anything with Fennec/Android for months, so I guess we can close it.

Thanks Ethan.
