In android is there a way to check if the service is already bound before binding to it?

Question

I have multiple fragment activities and one of them is bound to a service that is constantly receiving messages. While I was switching between activities at one point I get the following error. I do not know how the List item is being clicked where the service is being bounded. In anyways I was wondering if I can add a check before I bind to see if the service is already running and connected.

Answer 1

Not sure if you ever found an adequate answer, but I just created a wrapper class I called ExtendedServiceConnection which basically had the ability to track and check whether it's Service was bound.

Just a tad cleaner then holding a global in Constants.

 private class ExtendedServiceConnection implements ServiceConnection {

    private boolean isServiceConnected = false;

    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
        Timber.d("Service Connection established with " + name.getShortClassName());
        isServiceConnected=true;
    }

    @Override
    public void onServiceDisconnected(ComponentName name) {
        Timber.d("Service Connection destroyed with " + name.getShortClassName());
        isServiceConnected=false;
    }

    public boolean isServiceConnected() {
        return isServiceConnected;
    }
}

Usage

public void onReceivePause() {
    if (mExtendedServiceConnection.isServiceConnected()) {
        unbindService(orientationServiceConnection);
    }
    handleNotifications(mPackage.isIntentionalPaused());
}
