Merge "Rebind TISBinder if service killed during connection" into sc-v2-dev

    private final ServiceConnection mTisBinderConnection = new ServiceConnection() {

        @Override

        public void onServiceConnected(ComponentName componentName, IBinder iBinder) {

            if (!(iBinder instanceof TISBinder)) {

                // Seems like there can be a race condition when user unlocks, which kills the TIS

                // process and re-starts it. I guess in the meantime service can be connected to

                // a killed TIS? Either way, unbind and try to re-connect in that case.

                unbindService(mTisBinderConnection);

                mHandler.postDelayed(mConnectionRunnable, BACKOFF_MILLIS);
