Android disable settings button in keyboard or block settings screen

Question

On my Samsung tablet i want to prevent user change keyboard settings, because malicious user from keyboard settings can block my tablet (used as kiosk).

I override dispatchKeyEvent in activity, but it doesn't called when i click settings button.

I also registered a watchdog to be notified on foreground activity, but the device settings doesn't appear in foreground activity.

Ideas?

SOLVED

This is the solution to get the foreground activity and force close

ActivityManager.RunningAppProcessInfo processInfo = mActivityManager.getRunningAppProcesses().get(0);
if (processInfo != null && processInfo.pkgList != null && processInfo.pkgList.length > 0) {
    mCurrentApp = processInfo.pkgList[0];
    Runtime.getRuntime().exec(new String[]{"su", "-c", "am force-stop " + mCurrentApp}).waitFor();
}

I had this problem long back. I will revert you solution. – Paritosh Apr 24 '15 at 10:04 — Paritosh, Apr 24 '15 at 10:04
