From time to time, I can see logcat messages reporting activity leak. For example:
Activity com.android.internal.app.ChooserActivity has leaked IntentReceiver com.android.internal.app.ResolverActivity$1#4144d6e8 that was originally registered here. Are you missing a call to unregisterReceiver()?

My question is: how is this activity leak detected?
To detect memory leak in code, you need to install Memory Analyzer Tool plugin for eclipse.
To understand how to use MAT, please see the following link: http://android-developers.blogspot.in/2011/03/memory-analysis-for-android.html
This is a very useful plugin, though a bit difficult to understand at first go but as you will use it, you will detect the memory leak in no time.
If you face any difficulty, please ask me anytime.
Thank you :)

but I can't see where is it thrown in my code, and I can't find out how prevent it.
I can't reproduce this issue, but it occured at my users.
BroadcastReceiver you registered went out of scope or you attempted to register null object. Stop app on line where you register receiver in debuger and see if it is a null.
when i am using facebook login button in my activity, logcat shows up this. I don't get it why this showing up I checked entire class never found a reference.

Window leak exception often occurs if Dialog not used properly(such as not finished before jumping to another activity). And Google has reminded developers that DialogFragment is a better choice than Dialog.
We're seeing quite a few of these exceptions in our crash logging tool.
The stacktrace contains only android functions:

How would you proceed with finding the cause of this?
We can't get more information than this I'm afraid.
My guess is we're trying to show a popup or something after the activity has died.
This is usually linked to keeping references to a dead Context or starting a Dialog with the wrong Context.
my application crashed when I start it again after closing it for quite some time. Below you can see the log that shows the error:

I'm looking for the solution or at least someone with similar problem but surprisingly there is none.
Someone can help me?
Thank you!
I have integrated zxing barcode scanner in my app. When the scanner gets a scan it takes the result and searches an external online database via a async task then opens a new activity based on the results. I am getting a force close that is not consistent, it does not happen every scan, only sometimes so I am having trouble figuring out why I am getting a leaked window error, and only sometimes:

From the stack trace, it looks like your Dialog isn't visible when the AsyncTask finishes its work. In that case, the call to dismiss() will crash the app.
You might try using Dialog.isShowing() to avoid the crash:
protected void onPostExecute(...) {
...
if (dialog.isShowing()) {
dialog.dismiss(); // or .cancel()
}
...
}
