Designing Android apps for tablets

Question

In the Play developer console it says:

Your APK does not seem to be designed for tablets

But I have added layouts to layout-sw600dp, layout-sw600dp-land, layout-sw720dp and layout-sw720dp-land folders. The complete manifest (as it is):

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.technicosa.unjumble"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="18" />

<supports-screens
    android:anyDensity="true"
    android:largeScreens="true"
    android:normalScreens="true"
    android:resizeable="true"
    android:smallScreens="true"
    android:xlargeScreens="true" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/Theme.Sherlock.Light.DarkActionBar" >
    <activity
        android:name="com.technicosa.unjumble.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.technicosa.unjumble.UserSettingsActivity"
        android:label="@string/title_activity_user_settings" >
    </activity>
</application>

The app runs perfectly on both Nexus 7 and Nexus 10 in the emulator. Also in the developer console under optimization tips it says:

Your Production APK needs to meet the following criteria: Uses available screen space on 10-inch tablets

A screenshot of my app:

While the app seems to run on tablets (I have tested only on emulator), what must be done to fulfill the Play criteria?

Answer 1

Replacing folders layout-sw600dp, layout-sw600dp-land, layout-sw720dp and layout-sw720dp-land with layout-xlarge, layout-xlarge-land added a new message: "your apk does not seem to be designed for tablets."

Solved the problem after what's stated here.

Take advantage of extra screen area available on tablets

• Look for opportunities to include additional content or use an alternative treatment of existing content.

• Use multi-pane layouts on tablet screens to combine single views into a compound view. This lets you use the additional screen area more efficiently and makes it easier for users to navigate your app.

The problem was really the white space and had nothing to do with the xmls.

I managed to make the message for 7i tabs go away by rearranging the layouts to cover the screen and not leave too much white space. But not for the 10i tablets as the area is too big and my app has very less content. I must consider additional content.
