Close(kill) another app in my application by package name - xamarin.android

Question

I would like to close(kill) another app in my application by package name. I am trying something like this, but this code don't close any app. what am i doing wrong?
public void amKillProcess(string package_name)
{
ActivityManager am = (ActivityManager)this.GetSystemService(Context.ActivityService);
IList<RunningAppProcessInfo> runningProcesses = am.RunningAppProcesses;
foreach (RunningAppProcessInfo runningProcess in runningProcesses)
{
if (runningProcess.ProcessName.Contains(package_name))
{
Android.OS.Process.SendSignal(runningProcess.Pid, Signal.Kill);
am.KillBackgroundProcesses(runningProcess.ProcessName);
}
}
}
P.S I added android.permission.KILL_BACKGROUND_PROCESSES and by this code i can close only my own app

If you want to kill a background app , check the following code
public void amKillProcess(string package_name)
{
ActivityManager am = (ActivityManager)this.GetSystemService(Context.ActivityService);
var runningProcesses = am.RunningAppProcesses;
foreach (RunningAppProcessInfo runningProcess in runningProcesses)
{
if (runningProcess.ProcessName.Contains(package_name))
{
Android.OS.Process.KillProcess(runningProcess.Uid);
}
}
}
And if you want to kill a foreground app, you could use Adb
public class SuUtil
{
private static Java.Lang.Process process;
public static void kill(string packageName)
{
initProcess();
killProcess(packageName);
close();
}
private static void initProcess()
{
if (process == null)
try
{
process = Runtime.GetRuntime().Exec("su");
}
catch (IOException e)
{
}
}
private static void killProcess(string packageName)
{
System.IO.Stream output = process.OutputStream;
Java.Lang.String cmd = new Java.Lang.String("am force-stop " + packageName + " \n");
try
{
output.Write(cmd.GetBytes());
output.Flush();
}
catch (IOException e)
{
}
}
private static void close()
{
if (process != null)
try
{
process.OutputStream.Close();
process = null;
}
catch (IOException e)
{
}
}
}
