Android: NullPointerException at android.app.ActivityThread$PackageInfo$ServiceDispatcher.doConnected(ActivityThread.java:1012)

Question

Hello,
I am getting a NullPointerException at android.app.ActivityThread$PackageInfo$ServiceDispatcher.doConnected(ActivityThread.java:1012). My application is not even in the stack trace, so I have no idea what is going on. I am trying to connect to a service when it happens. How can I fix this problem? Thanks, Isaac Waller

This probably way too old for my response to be of any use, but in case anybody else has this problem, here's what it was for me. I am using a newer version of the SDK, so I'm getting this issue at line 1061.

It was happening to me because I was passing a null ServiceConnection object to the function bindService.

It was helpful to browse the SDK code in my case - although the line numbers don't add up due to version differences, the general code is likely the same (and I knew which method to check):

1097                 // If there was an old service, it is not disconnected.
1098                 if (old != null) {
1099                     mConnection.onServiceDisconnected(name);
1100                 }
1101                 // If there is a new service, it is now connected.
1102                 if (service != null) {
1103                     mConnection.onServiceConnected(name, service);
1104                 }

mConnection was pretty much the only thing that made sense to be null.
