How can I determine whether a device is a tablet or a mobile phone?

Currently, mobile phones on the market are generally smaller than 6 inches, while tablets are generally larger than 6 inches. Therefore, you can determine whether the device is a tablet or mobile phone by calculating the device size.

The judgment code is as follows:

Public static boolean isTablet (Activity activity) {DisplayMetrics dm = new DisplayMetrics (); activity. getWindowManager (). getdefadisplay display (). getMetrics (dm); double diagonalPixels = Math. sqrt (Math. pow (dm. widthPixels, 2) + Math. pow (dm. heightPixels, 2); double screenSize = diagonalPixels/(160 * dm. density); return screenSize> = 6.0D ;}
