tiapp.xml android manifest entry crashes emulator

• app: android mobile
• android sdk: 4.4
• sdk 3.1.2
• os: osx mavericks
• studio Titanium Studio, build: 3.1.3.201309132423
• output: Android emulator WXGA800 7in tablet

While researching a different problem, TabGroup opens over window view, I found a suggestion about adding elements to my android manifest, so I thought I'd try it. When I add the element

<uses-sdk android:maxSdkVersion="18" android:minSdkVersion="11" android:targetSdkVersion="18"/>

as part of this entry

<property name="ti.android.fastdev" type="bool">false</property>
    <android xmlns:android="http://schemas.android.com/apk/res/android">
        <manifest>
            <tool-api-level>14</tool-api-level>
            <supports-screens android:anyDensity="false"/>
            <uses-sdk android:maxSdkVersion="18"
            android:minSdkVersion="10" android:targetSdkVersion="18"/>
        </manifest>
    </android>

the emulator crashes with this console output

[ERROR] :  Emulator process exited with code 1
[ERROR] :  Build process exited with code 1
[ERROR] :  Project failed to build after 695ms
[ERROR] Application Installer abnormal process termination. Process exit value was 1

When I remove that element, the emulator proceeds normally. Why would that line cause a crash? Is it a value mismatch on the sdk versions? There's no IDE error log output so that's no help. BTW, this did nothing to resolve my original issue. That's still waiting for a response from the community.
