App not Ice Cream Sandwich compatible

Question

I've developed an application for Android that cannot be download to Android ICS devices from the Market. Browsing the market with a 4.x device people see a "not compatible warning" and cannot proceed with the download. The app has a minSdkVersion setting of 7. It works well on 2.x and 3.x Android devices. I don't know what to do and how I can fix this. Do I need to setup anything special in order to be compatible with ICS? I cannot find any information on this subject.

Update: I just received confirmation that installing the APK by hand works on a 4.0 device. It just won't install through the market! Again, it shows as "not compatible for your device" in the market. Any ideas?

AndroidManifest.xml:

    <activity android:name=".SelectLocationActivity" android:label="@string/app_name"

    <!-- Info Activity-->
    <activity android:name=".InfoActivity" android:label="@string/app_name"
        android:theme="@style/NatuurijsTheme">
    </activity>

</application>
</manifest>

Could it be the theme? the theme is not anything special. It simply inherits from Theme.Black.NoTitleBar

<style name="NatuurijsTheme" parent="android:Theme.Black.NoTitleBar"></style>

Answer 1

Is your app copy-protected under "publishing options" in the play store publish section? Source: My Android App shows as "this item is not compatible with your device"

Answer 2

I was getting similar complaints from my app. One thing I noticed with my app was that I was using a Tab Activity which is now deprecated in Android 4.0+. (Phones without a hard menu key will not be able to use an Options Menu if you use a TabActivity/TabHost which is a problem.) I replaced my tabs with normal buttons for app navigation and I believe this might have fixed my ICS compatibility issues.

Also, I tried updating my manifest android:minSdkVersion and ADDED android:targetSdkVersion , but I'm not sure if those actually fixed anything.

Note: If you need help finding your deprecated code, try telling Eclipse to show deprecated functionality as an error by changing the project properties.

EDIT:

More information: Apparently I still have some issues with ICS compatibility so the above is not the only thing I need to fix. Still not sure what else I can do. One thing I found in my research is that apparently people with custom ROMS sometimes have "incorrect XML values" which makes the Google Play store say that they aren't compatible. Perhaps downloading through the web version of Google Play and asking users to install remotely from there might solve our problems.

EDIT 2:

Your app should no longer use the copy-protection under "Publishing Options" in the Google Play Store publish section.
