How to check if my app is still running in an Android service?

I'm starting to develop an Android sticky service for my app with Delphi 10.1 Berlin, but I haven't found any tutorial or book that get into it, so I'm asking:

Which is the simplest way to detect if my app is still running or has been killed by the OS/user?

Solution

  • You can look for the process id by package name and see if it is still active.

    ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> pids = am.getRunningAppProcesses();
int processid = 0;
for (int i = 0; i < pids.size(); i++) {
    ActivityManager.RunningAppProcessInfo info = pids.get(i);
    if (info.processName.equalsIgnoreCase("packageNameSearchingFor")) {
       processid = info.pid; //found it, we are running
    } 
}

    Or you can simply store a shared value in public shared pref or database accessible through ContentProvider that is updated when in foreground or background to check. Either way is fine.
