Android Bind service call Interface issue`

Question

I am facing an error while binding the service with interface stub().

Here is my Connection code:

class LogConnection implements ServiceConnection {

    public void onServiceConnected(ComponentName className,
            IBinder boundService) {
        logService = ILogService.Stub.asInterface((IBinder) boundService);
    }

but its not working for me.

Logcat:

06-22 12:17:28.632: I/dalvikvm(1973): Could not find method com.sam.logservice.ILogService$Stub.asInterface, referenced from method com.sam.logclient.LogClientActivity$LogConnection.onServiceConnected

06-22 12:17:28.702: W/ActivityManager(61): Unable to start service Intent { cmp=com.sam.logclient/com.sam.logservice.ILogService }: not found

EDIT: I am following the example of below link :

Remote Service call

When I did Debugging the code at that time I struck at the same position

  logService = ILogService.Stub.asInterface((IBinder) boundService);

Hope you have some solution.

Please let me know if you want more data to conclude on reason.

In your code I observed thats why are you casting boundService it to IBinder there is actually no need to cast it just pass it as it is. So, your line should look like this

  logService = ILogService.Stub.asInterface(boundService);

make sure the service written in same package ..

The class where your extending service just create object of interface

 ILogService.Stub logService = new ILogService.Stub();

and in onBind method return it as shown below

 @Override
    public IBinder onBind(Intent intent) {
        return logService;
    }

Hope this explanation works for you .
