Android - Standard height of toolbar

Question

I want to create a toolbar in my app, and I am wondering what is the standard height for the toolbar in android?

I want it to be big enough for a finger, but not huge.

You can use the following method to get the AppBar height programatically

private static final int DEFAULT_TOOLBAR_HEIGHT = 56;

private static int toolBarHeight = -1;

public static int getToolBarHeight(Context context) {
        if (toolBarHeight > 0) {
            return toolBarHeight;
        }
        final Resources resources = context.getResources();
        final int resourceId = resources.getIdentifier("action_bar_size", "dimen", "android");
        toolBarHeight = resourceId > 0 ?
                resources.getDimensionPixelSize(resourceId) :
                (int) convertDpToPixel(DEFAULT_TOOLBAR_HEIGHT);
        return toolBarHeight;
    }

public static float convertDpToPixel(Context context, float dp) {
    float scale = context.getResources().getDisplayMetrics().density;
    return dp * scale + 0.5f;
}
