Tablet or Phone - Android

Question

Is there a way to check if the user is using a tablet or a phone? I\'ve got problems with my tilt function and my new tablet (Transformer)

Answer 1

below method is calculating the device screen's diagonal length to decide the device is a phone or tablet. the only concern for this method is what is the threshold value to decide weather the device is tablet or not. in below example i set it as 7 inch and above.

public static boolean isTablet(Activity act)
{
    Display display = act.getWindow().getWindowManager().getDefaultDisplay();
    DisplayMetrics displayMetrics = new DisplayMetrics();
    display.getMetrics(displayMetrics);

    float width = displayMetrics.widthPixels / displayMetrics.xdpi;
    float height = displayMetrics.heightPixels / displayMetrics.ydpi;

    double screenDiagonal = Math.sqrt( width * width + height * height );
    int inch = (int) (screenDiagonal + 0.5);
    Toast.makeText(act, "inch : "+ inch, Toast.LENGTH_LONG).show();
    return (inch >= 7 );
}
