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

Answer 1

Re: the tangent above on how to tell a phone from a non-phone: as far as I know, only a phone has a 15-digit IMEI (International Mobile Station Equipment Identity), so the following code will definitively distinguish a phone from a non-phone:

    TelephonyManager manager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
    String deviceInfo = "";
    deviceInfo += manager.getDeviceId(); // the IMEI
    Log.d(TAG, "IMEI or unique ID is " + deviceInfo);

    if (manager.getDeviceId() == null) {
        Log.d(TAG, "This device is NOT a phone");
    } else {
        Log.d(TAG, "This device is a phone.");
    }

I have found that on a Nook emulator getPhoneType() returns a phoneType of "GSM" for some reason, so it appears checking for phone type is unreliable. Likewise, getNetworkType() will return 0 for a phone in airplane mode. In fact, airplane mode will cause getLine1Number() and the getSim* methods to return null too. But even in airplane mode, the IMEI of a phone persists.

The best option I found and the less intrusive, is to set a tag param in your xml, like

PHONE XML LAYOUT

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:tag="phone"/>

TABLET XML LAYOUT

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:tag="tablet">

    ...

</RelativeLayout>

and then call this in your activity class:

View viewPager = findViewById(R.id.pager);
Log.d(getClass().getSimpleName(), String.valueOf(viewPager.getTag()));

Hope it works for u.

I use this method in all my apps, and it works successfully:

public static boolean isTablet(Context ctx){    
    return (ctx.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) >= Configuration.SCREENLAYOUT_SIZE_LARGE; 
}
