Why Intellij Idea shows compatible="no" for android emulator

Question

Intellij Idea shows compatible="no" for every android emulator. I tried emulators with different api levels. At the same time compatible="true" for my NexusOne.

Does anyone know how it checks device/emulator for compatibility?

I have next settings in manifest:

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="4"/>

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_APN_SETTINGS"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

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

It could happen because of a known bug when you install SDK while IntelliJ IDEA is running. Restarting IntelliJ IDEA should fix the problem.
