How to know smallest width (sw) of an android device?

Issue

I have 4 different devices:

1. Asus tablet, screensize 7"
2. Lenovo tablet, screensize 7"
3. HTC mobile phone, screensize 5"
4. HTC mobile phone, screensize 4.7"

I want to know the smallest width (sw) of my device to make a support layout for it.

I want to make a resource folder like "layout-sw600dp" but I don't know the value of the smallest width (sw).

I tried to print the sw using this code:

DisplayMetrics metrics = getResources().getDisplayMetrics();
Log.i("Density", ""+metrics.densityDpi);

but i don't know if this is the correct value.

How do I find the smallest width (sw)?

Solution

you can try this:

DisplayMetrics dm = mActivity.getApplicationContext()
                    .getResources().getDisplayMetrics();
            float screenWidth = dm.widthPixels / dm.xdpi;
            float screenHeight = dm.heightPixels / dm.ydpi;
