Re: Android Service Tutorial - ServiceConnection leak

[Lars Vogel]

Hi Alex,

thanks for the report. I adjusted the tutorial so that the lifecycle of the Activity is correctly considered.

Best regards, Lars

Hi,

Thanks, for all the great tutorials, I've found them really useful.

I just have a comment/feedback about the Android Service Tutorial (http://www.vogella.com/articles/AndroidServices/article.html), specifically the code in section 8 (Define and consume your own service).

Although the code functions fine, when I close the application I get the following error in my logcat regarding ServiceConnection leak:

08-13 15:03:59.461: E/ActivityThread(355): Activity org.digitalcampus.testing.MainActivity has leaked ServiceConnection org.digitalcampus.testing.MainActivity$1@44f44458 that was originally bound here

...

However, I fixed this by adding the following to the MainActivity class:

public void onDestroy() {
    mConnection = null;
}


Not sure if there is another (better) way to handle this, but it seemed to work for me. For info I was running the code on Android 2.3.7 (Cyanogenmod),


Cheers,
Alex
