    Don't be too ironic. The question you have asked has been asked too many times on SO with a code too. So first search for existing solution. Few threads are http://stackoverflow.com/questions/9804786/how-to-kill-a-3rd-party-application , http://stackoverflow.com/questions/12892400/get-running-processes-list-and-kill-their-background-services and http://stackoverflow.com/questions/2720164/android-process-killer. – Pankaj Kumar May 29 '14 at 07:32

You can use Process.killProcess(int pid) to kill processes that have the same UID with your App. You can use ActivityManager.killBackgroundProcesses(String packageName),with KILL_BACKGROUND_PROCESSES permission in your manifest(for API >= 8) or ActivityManager.restartPackage (String packageName)(for API < 8) to kill specified process,except of forground process.

So if you would to kill all other processes when your program is foreground process,you would to use ActivityManager.killBackgroundProcesses or ActivityManager.restartPackage:

List<ApplicationInfo> packages;
    PackageManager pm;
    pm = getPackageManager();
    //get a list of installed apps.
    packages = pm.getInstalledApplications(0);

    ActivityManager mActivityManager = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);

   for (ApplicationInfo packageInfo : packages) {
        if((packageInfo.flags & ApplicationInfo.FLAG_SYSTEM)==1)continue;
        if(packageInfo.packageName.equals("mypackage")) continue;
        mActivityManager.killBackgroundProcesses(packageInfo.packageName);
   }

In above snippet code,each process will be killed unless it be process of your App or system process.
