And here is what logcat outputs when launching the app from the "Open"
button, and from the app tray. Looks like it's using a different way
of opening from the app tray:
// When starting from the app tray:
INFO/ActivityManager(1714): Starting activity:
Intent { action=android.intent.action.MAIN categories=
{android.intent.category.LAUNCHER} flags=0x10200000 comp=
{com.test.testapp/com.test.testapp.ActivityA} }
// When starting from the "Open" button through the browser:
INFO/ActivityManager(1714): Starting activity:
Intent { action=android.intent.action.MAIN flags=0x10000000 comp=
{com.test.testapp/com.test.testapp.ActivityA} }
Thanks
