fix(android): report a package that is not installed when terminating it - #498
mobile-kevin wants to merge 2 commits into
Conversation
am force-stop exits 0 for any package name, so terminating an app that is not installed reported success. Check pm path first and fail with '<package> not installed', the message the iOS device and simulator give. Terminating an installed app that is not running still succeeds.
📝 Walkthrough
Merge Risk: 🔵 Low · up to If the package manager prints unexpected output while exiting successfully, termination reports the app as not installed instead of surfacing the real failure. This is a narrow, easily fixed gap; address it before or soon after merge. Pre-merge checks |

Reject non-empty output without a package: prefix.
If pm path exits successfully but prints non-empty output such as Error: package manager unavailable, pmPathReportsInstalled returns false, nil. TerminateApp then reports that the package is not installed instead of reporting the installation-check failure. Return an error whenever the trimmed output is non-empty and lacks the expected prefix. Add a test for this successful-exit case.

Problem
mobilecli apps terminate <package>on Android reports success for a package that is not installed, becauseam force-stopexits 0 for any name:The iOS device and the simulator (#493) already fail with
<package> not installed.Fix
AndroidDevice.TerminateAppcheckspm path <package>first and returns<package> not installedwhen it prints nothing. An installed app that is not running is still force-stopped without error, so callers that stop an app before relaunching it are unaffected.pm pathoutput is read by a small pure function,pmPathReportsInstalled, so an adb or device failure (non-empty output that is notpackage:…) is returned as an error instead of being read as "not installed".Cost: one extra
adb shell pm pathper terminate (~50 ms on an emulator).Testing
