Android :: Task Activity Stack Always Reset When Launched From Home

I am just starting on an Android app and I am puzzled about why my Task activity stack is being reset any time the application is launched from the Home screen. I used the ADT tools to create the application in Eclipse. The main activity is ".UserLaunch" and it starts the activity ".About" when the user presses a button. If the user then presses HOME and then relaunches the app, .UserLaunch is displayed and is the only thing on the stack.

.UserLaunch has the launchMode singleTask. .About is standard. According to the documentation at http://developer.android.com/guide/topics/fundamentals.html#lmodes: "However, a "singleTask" activity may or may not have other activities above it in the stack. If it does, it is not in position to handle the intent, and the intent is dropped. (Even though the intent is dropped, its arrival would have caused the task to come to the foreground, where it would remain.) "The Task stack should be brought to the foreground and .About should still be displayed. I added Logging to all of the lifecycle events (edited to remove timestamps and shorten DEBUG/ and INFO/ to D/ and I/) and you can see that when HOME is pressed, .About cycles through onPause and onStop (as expected). Then when the app is again launched, .About is destroyed and .UserLaunch is restarted D/UserLaunch:(670): onCreate() D/UserLaunch:(670): onStart() D/UserLaunch:(670): onResume() I/ActivityManager(52): Displayed activity com.cequint.cityid/.UserLaunch: 4910 ms I/ActivityManager(52): Starting activity: Intent { comp= {com.cequint.cityid/com.cequint.cityid.About} } D/UserLaunch:(670): onPause() D/About(670): onCreate() D/About(670): onStart() D/About(670): onResume() I/ActivityManager(52): Displayed activity com.cequint.cityid/.About: 1031 ms D/UserLaunch:(670): onStop() I/ActivityManager(52): Starting activity: Intent { action=android.intent.action.MAIN categories= {android.intent.category.HOME} flags=0x10200000 comp= {com.android.launcher/com.android.launcher.Launcher} } D/About(670): onPause() D/About(670): onStop() D/dalvikvm(670): GC freed 413 objects / 34128 bytes in 72ms I/ActivityManager(52): Starting activity: Intent { action=android.intent.action.MAIN categories= {android.intent.category.LAUNCHER} flags=0x10200000 comp= {com.cequint.cityid/com.cequint.cityid.UserLaunch} } D/About(670): onDestroy() D/UserLaunch:(670): onRestart() D/UserLaunch:(670): onStart() D/UserLaunch:(670): onResume() Here is the relevant section of the Manifest: <application android:icon="@drawable/icon" android:label="@string/ app_name"> <activity android:name=".UserLaunch" android:label="@string/app_name" android:launchMode="singleTask" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".About" android:launchMode="standard"> </activity> </application> Anyone have any ideas why this is always resetting the Activity Stack?
