How to close all background active applications?

Question

I have one requirement like, I want to close all background running applications. I used this code, but its not working...

    ActivityManager  manager =  (ActivityManager)this.getSystemService(Context.ACTIVITY_SERVICE);
    List<ActivityManager.RunningAppProcessInfo> listOfProcesses = manager.getRunningAppProcesses();
    for (ActivityManager.RunningAppProcessInfo process : listOfProcesses)
    {
        System.out.println(process.processName);
        manager.killBackgroundProcesses(process.processName);
    }

Any help?

and have you added `android.permission.KILL_BACKGROUND_PROCESSES` permission in manifest? — Gopal Gopi, Feb 18 '14 at 11:40
You need to pass the process's package name i.e. package name of the app to which the process belongs to. not the process name... — Gopal Gopi, Feb 18 '14 at 12:00
but 'process.processName' will gives the package name only... — Anil kumar, Feb 18 '14 at 12:03
Android sets a process for every package so when you close the package you kill the process as well — Hitman, Feb 18 '14 at 12:08

You can only kill your own apps, e.g. the ones running in the same process or with the same userID. You can not kill others, unless the device is rooted.

Try this

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);
    }
