خطا در استفاده از mLinearLayout.setLayoutParams

من از کد زیر استفاده می کنم:

    private int width = UIHelpers.width, height = UIHelpers.height;
    private LinearLayout ll_main, ll_main_inner, ll_main_footer;

// onCreate


        returnDisplaySize();
        Log.i("ssize", "Screen Size Of Device \n width:" + UIHelpers.width + " & height: " + UIHelpers.height);

        // ============================================================ LinearLayouts

        ll_main = (LinearLayout) findViewById(R.id.ll_main);
        // ll_main.setLayoutParams(new LayoutParams(width, height));
        /*
        android.view.ViewGroup.LayoutParams ll_main_Params = ll_main.getLayoutParams();
        ll_main_Params.width = width;
        ll_main_Params.height = height;
        ll_main.setLayoutParams(ll_main_Params);
         */

        int inner_width, inner_height;
        inner_width = width;
        inner_height = (int) (height * 0.70);

        ll_main_inner = (LinearLayout) findViewById(R.id.ll_main_inner);
        ll_main_inner.setLayoutParams(new LayoutParams(inner_width, inner_height));
        ll_main_inner.setBackgroundColor(Color.parseColor("#FFFFFF"));

        int footer_width, footer_height;
        footer_width = width;
        footer_height = (int) (height * 0.30);

        ll_main_footer = (LinearLayout) findViewById(R.id.ll_main_footer);
        ll_main_footer.setLayoutParams(new LayoutParams(footer_width, footer_height));

 

 
   private void returnDisplaySize() {

        UIHelpers uiHelpers = new UIHelpers();
        uiHelpers.getScreenSize();
        // Log.i("ssize", "Screen Size Of Device heightPixels: " + G.configs.context.getResources().getDisplayMetrics().heightPixels);
        // Log.i("ssize", "Screen Size Of Device widthPixels: " + G.configs.context.getResources().getDisplayMetrics().widthPixels);
        UIHelpers.height = G.configs.context.getResources().getDisplayMetrics().heightPixels;
        UIHelpers.width = G.configs.context.getResources().getDisplayMetrics().widthPixels;

    }

اما برنامه کرش می کنه
