How do I know if the application works on a tablet or mobile device in Android?

Question

I am developing an Android application that is compatible for a mobile screen and tablet screen.

So, I create 4 different screens for each. it

• login_portrait.xml
• login_landscape.xml
• login_portrait_large.xml
• login_landscape.xml

But the problem is, how to find that my application used by any user is using a tablet or mobile phone?

Is there any solution?

Answer 1

Go For this link:

Android Developer

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

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

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

"" ( res/values ​​/) boolean false:

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

, :

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

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