Android RuntimeException: Unable to instantiate the service

Problem: starting an IntentService generates a RuntimeException.

I’m clueless. If you need more info, just ask. Log:

This code calls the service (it’s being called from a ContentProvider):

Intent i = new Intent(
        getContext(),
        MyService.class);
    i.putStringArrayListExtra(EXTRA_MISSING, missingMonths);
    i.putExtra(EXTRA_URI, uri);
    i.putExtra(EXTRA_START, startTime);
    i.putExtra(EXTRA_END, endTime);
    getContext().startService(i);

And this is the IntentService relevant code blocks (there are only two methods. Besides the asynctask itself, of course):

public MyService(String name) {
    super("MyService");
}

@Override
protected void onHandleIntent(Intent intent) {
        // ... do stuff
        new DownloaderTask().execute(missingMonths);
}

You appear to be missing the zero-argument public constructor. Delete the String name from your current constructor (since you’re not using it anyway), and you should be good to go.
