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 ?

its kind of late but There was this app on the playstore which will get you what you are looking for without writing a code snippet but unfortunately the app is removed from google play store but i was able to extract the apk from my installed device and have uploaded it to following link: https://www.mediafire.com/?2jccjo17mvxgljt Hope this helps you in getting what are you looking for. Do let me know if that helped you or not — Niranjan Balkrishna Prajapati, Mar 13 '14 at 07:22
If you want a quick reference, Google provides screen details of a few popular devices: https://design.google.com/devices/ — rpattabi, Nov 25 '16 at 09:28

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();
}

This answer doesn't actually answer the question. It's asking about density, not size. – kabuko Feb 25 '13 at 06:33

@SiddharthLele I have found it because of you....thanks – Pragnani Feb 25 '13 at 06:34
I dont want to code - seeing the mobile could I? Purpose : Samsung S4 is coming to market in march - I want to know the density , – Sreeram Feb 25 '13 at 06:48
@Sreeram "seeing the mobile" in the sense...you can find the phone spefications in http://www.gsmarena.com/samsung_galaxy_s_iv-5125.php – Pragnani Feb 25 '13 at 06:50
@Pragnani - Might be fundamental but please ignore - Using GSM arena, how could I find the device device - Now my objective is to find S4 belongs to HDPI/XHDPI. – Sreeram Feb 25 '13 at 07:36
@Sreeram That is what we(me and Gabe Sechan) have posted. I'll update it for you make you clear – Pragnani Feb 25 '13 at 07:50

As per what Gabe and you posted, I need to code the snippet - run it on the device and find the device type. But the requirement is looking at the device , knowing the screen spec's - could I find the device type - I remember a formula not clear [square root of width* height]/length .. blah blah .. if the value is <1 >1 >1.25 >1.50 I could find the device type. Could you explain it for me. – Sreeram Feb 25 '13 at 08:03

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int density = dm.densityDpi;

The density variable is a constant defined in DisplayMetrics corresponding to the different dpis.

Use google and search then. And then you're asking on the wrong site- this is a site for asking programming questions, not about device specs. – Gabe Sechan Feb 25 '13 at 14:01
