A bit more information n this issue. Cordova repeately does `ps` command in the adb shell https://github.com/apache/cordova-android/blob/e86b211cd18e3df1932a970d2f431b208a98ae42/bin/templates/cordova/lib/emulator.js#L356 And looks for `android.process.acore`. On a fresh boot of the emulator running `ps` command on the emulator I clearly see this process. Over time however `ps` returns: ``` generic_x86_arm:/ $ ps USER PID PPID VSZ RSS WCHAN ADDR S NAME shell 5113 25902 12176 3848 0 0 R ps shell 25902 386 12932 3124 __ia32_co+ 0 S sh ``` Even `ps -A` to return all processes, including processes owned by root fails to have `android.process.acore` listed. Further research shows that `android.proces.acore` is a process responsible for android's [ContactsProvider](https://android.googlesource.com/platform/packages/providers/ContactsProvider/+/android-5.1.1_r29/AndroidManifest.xml#22) system. I don't believe scanning for the `android.process.acore` is a reliable way to determine if the system is booted. It looks like it works on cold boots, but eventually the process is killed (probably when it isn't being used). Despite it's name, it has nothing to do with it being an android core (which I think was probably what the original author of the cordova codebase thought, with no blame) Unfortunately it seems to be very difficult to determine if the emulator is ready to be used. `get prop sys.boot_completed` appears to be one approach, but not all simulators use it (according to SO comments). Personally if android simulators (from what google provides) from android 5.1 to latest (ie the android versions cordova-android@9 will support) all supports `sys.boot_completed` prop, I think that is our best path forward. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
