Determine if the device is a smartphone or tablet? [duplicate]

Question

I would like to get info about a device to see if it's a smartphone or tablet. How can I do it?

I would like to show different web pages from resources based on the type of device:

String s="Debug-infos:"; s += "\n OS Version: " + System.getProperty("os.version") + "(" +    android.os.Build.VERSION.INCREMENTAL + ")"; s += "\n OS API Level: " + android.os.Build.VERSION.SDK; s += "\n Device: " + android.os.Build.DEVICE; s += "\n Model (and Product): " + android.os.Build.MODEL + " ("+ android.os.Build.PRODUCT + ")"; 

However, it seems useless for my case.

This solution works for me now:

DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); int width = metrics.widthPixels; int height = metrics.heightPixels;  if (SharedCode.width > 1023 || SharedCode.height > 1023){    //code for big screen (like tablet) }else{    //code for small screen (like smartphone) } 

Answer 1

This subject is discussed in the Android Training:

Use the Smallest-width Qualifier

If you read the entire topic, they explain how to set a boolean value in a specific value file (as res/values-sw600dp/attrs.xml):

<resources>     <bool name="isTablet">true</bool> </resources> 

Because the sw600dp qualifier is only valid for platforms above android 3.2. If you want to make sure this technique works on all platforms (before 3.2), create the same file in res/values-xlarge folder:

<resources>     <bool name="isTablet">true</bool> </resources> 

Then, in the "standard" value file (as res/values/attrs.xml), you set the boolean to false:

<resources>     <bool name="isTablet">false</bool> </resources> 

Then in you activity, you can get this value and check if you are running in a tablet size device:

boolean tabletSize = getResources().getBoolean(R.bool.isTablet); if (tabletSize) {     // do something } else {     // do something else }
