How to find the device as LDPI MDPI HDPI or XHDPI

Question

Without any code snippet for the application, how to get screen resolution and length of the screen. How could I find whether the device is ldpi, mdpi , hdpi or xhdpi ?

Answer 1

Edit: use DisplayMetrics to get the density of the screen

getResources().getDisplayMetrics().densityDpi;

this will return the int value that represents the following constants. DisplayMetrics.DENSITY_LOW ,DisplayMetrics.DENSITY_MEDIUM, DisplayMetrics.DENSITY_HIGH, DisplayMetrics.DENSITY_XHIGH

  int density= getResources().getDisplayMetrics().densityDpi;

switch(density)
{
case DisplayMetrics.DENSITY_LOW:
   Toast.makeText(context, "LDPI", Toast.LENGTH_SHORT).show();
    break;
case DisplayMetrics.DENSITY_MEDIUM:
     Toast.makeText(context, "MDPI", Toast.LENGTH_SHORT).show();
    break;
case DisplayMetrics.DENSITY_HIGH:
    Toast.makeText(context, "HDPI", Toast.LENGTH_SHORT).show();
    break;
case DisplayMetrics.DENSITY_XHIGH:
     Toast.makeText(context, "XHDPI", Toast.LENGTH_SHORT).show();
    break;
}

This will return following constants based on thsi you can identify the device

Try this

int screenSize = getResources().getConfiguration().screenLayout &
        Configuration.SCREENLAYOUT_SIZE_MASK;

switch(screenSize) {
    case Configuration.SCREENLAYOUT_SIZE_LARGE:
        Toast.makeText(this, "Large screen",Toast.LENGTH_LONG).show();
        break;
    case Configuration.SCREENLAYOUT_SIZE_NORMAL:
        Toast.makeText(this, "Normal screen",Toast.LENGTH_LONG).show();
        break;
    case Configuration.SCREENLAYOUT_SIZE_SMALL:
        Toast.makeText(this, "Small screen",Toast.LENGTH_LONG).show();
        break;
    default:
        Toast.makeText(this, "Screen size is neither large, normal or small" , Toast.LENGTH_LONG).show();
}
