### Question:
AndroidUtils { public static int convertToPix(float density, int sizeInDips) { float size = sizeInDips * density; return (int) size; } private  AndroidUtils(); static void toggleKeyboard(Context context); static void requestHideKeyboard(Context context, View v); static int convertToDip(DisplayMetrics displayMetrics, int sizeInPixels); static int convertToPix(float density, int sizeInDips); static String getVersionName(Context context); static int deviceDPI(Context c); static String deviceResolution(Context c); static boolean isServiceRunning(Class<? extends Service> service, Context context);  }### Answer:
@Test public void testConvertToPix() { int sizeInPix = AndroidUtils.convertToPix(DENSITY, SIZE_IN_DIPS); assertEquals(sizeInPix, SIZE_IN_PIX); }
