I guess you are trying to do too much. I cannot agree that launching such a trivial application as Notepad with only 2 activities is doing too much. The basic operation of launching an app is pretty straightforward, and it's definitely not broken. How can you support your words? I wrote precise steps, which led to bugs, but you are simply saying that there it nothing wrong without any prove. This is not helpful. Have you tried writing your own app and checking the behaviour? Yes. My application also have 2 activities and is very similar to Notepad. And my customers filed bugs related to multiple instances created. If you still face similar problems with your app, then perhaps, you should post your code and let others go through it. I disagree. I made an effort to reproduce the problem with the sample Notepad exactly to avoid posting my own messy code. We need to fix the standard sample, such as Notepad, so that I and other people would use it as an example.

I just checked the sample, with launch mode as standard, and, while I am on create note screen, I pressed Home button. I launched the app from the Launcher icon, and I could see the editor screen.

Sorry, What I meant was, after opening the app multiple times, and pressing the Home button multiple times, I could not see multiple instances of the activity. I just had to press BACK once, and it was gone. Sorry, but you did not follow my steps. I guess that you did not follow the very first step: 1. When installing NotePad application tap Open. This makes the difference: when you launch an application from Installer, then press Home button and then launch it again from the Home screen you get multiple instances of the main activity. This is by design of launchMode:standard And this causes the bug. I just verified them on DroidX one more time. Let me repeat the steps: 1. When installing NotePad application tap Open. 2. Create a new note, begin editing, then press Home button. 3. Launch NotePad from the home screen - the editor disappeared, only the list displayed. This is bug #1. 4. Tap on the note and continue editing. 5. Note: if user continues repeating Home/Launch cycle, then there may be multiple activities created and the application will run out of memory. 6. Press Back. Return to the list. 7. Press Back. Again see the editor! This is bug #2 (actually it is the same bug, but customers are not aware of it and report it separately). 8. Press Back. Return to the list. 9. Press Back. Return to the home screen. Now the application is closed. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: How to launch an application? Is there a work around for launchMode bug?
http://code.google.com/p/android/issues/detail?id=2373
Which is mentioned in comment #5 of the issue that I supplied
Yes. Thank you.
I implemented the changes in Notepad:
1. Inserted
activity android:name=.StartupActivity
android:configChanges=orientation|keyboardHidden
android:theme=@android:style/Theme.NoTitleBar.Fullscreen
intent-filter
action android:name=android.intent.action.MAIN /
category
android:name=android.intent.category.LAUNCHER /
/intent-filter
/activity
to AndroidManifest of Notepad
2. Remove
intent-filter
action android:name=android.intent.action.MAIN /
category
android:name=android.intent.category.LAUNCHER /
/intent-filter
from
activity android:name=NotesList
3. Insert
uses-permission android:name=android.permission.GET_TASKS /
4. Copy StartupActivity.java to NotePad\src\com\example\android
\notepad
5. Change Package name, change
new Intent(StartupActivity.this, MainActivity.class);
to
new Intent(StartupActivity.this, NotesList.class);
Just a summary: StartupActivity.needStartApp does something like:
getSystemService(Context.ACTIVITY_SERVICE);
tasksInfo = getRunningTasks(1024);
size = tasksInfo.size();
for (int i = 0; i size; i++) {
if
(ourAppPackageName.equals(tasksInfo.get(i).baseActivity.getPackageName()))
{
return tasksInfo.get(i).numActivities == 1;
So, now the question is: how to get rid of GET_TASKS?
1. I am thinking whether it is possible to use a static variable to
keep track of running NotesList activity:
increment the variable in NotesList.onCreate and
decrement the variable in NotesList.onDestroy
Then instead of calling StartupActivity.needStartApp simply compare
the variable with 0.
2. Or change some Intent flags, as you suggested before.
So, what is the most proper way in your opinion?
Thank you
John
