Android System.err out of the blue

Question

While running my app, LogCat suddenly shows this barrage of orange-colored messages (warnings) which seem to be totally unrelated to my app (and certainly not having the same pid):

05-01 12:00:03.732: WARN/System.err(1836): java.io.FileNotFoundException: http://gh-pages.clockworkmod.com/ROMManagerManifest/premium_imei.js

05-01 12:00:14.202: WARN/System.err(1836):     at com.paypal.android.a.f.run(Unknown Source)

What does this mean? Is this is a bug in Android? A bug in some other external app or service running in the background?

How do I tell whether this has anything to do with my app-in-development?

(Note: My app doesn't use PayPal or ROM Manager in any way)

Answer 1

Maybe you should filter to 'Show only selected application'?

That way you'll see only stuff related to your app.

Answer 2

There's some kind of error occurring in what the ROM Manager is trying to do - probably a periodic check for new releases.

I wouldn't expect this has anything to do with your application, unless you see it happen during your application multiple times. And even then, I'd leave a logcat open when your app is not running and see if it's happening frequently.

You might want to think if you want to leave that rom manager installed/enabled...

Answer 3

If you aren't using them then it's just those services running in the background. Nothing you have to worry about.
