Enabling the Android Move To SD Card Feature
Edit the AndroidManifest.xml file of the application to add an entry for “android:installLocation” to the <manifest> tag:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" ......... android:installLocation="auto">
Keep the “minSdkVersion” the same as before; it need not be 8 to match Android 2.2
