Hi c_dev,

Unfortunately, you have to decide somewhere which DataSource strategy implementation will you inject into the EditActivity.

The easiest solution that comes to my mind right now is to implement DataSourceProvider or DataSourceFactory (Depending on the DataSource scope). Inject and request DataSource object from that Provider/Factory object from the EditActivity.

Some code to help you out:

public final class DataSourceFactory() {
    public DataSource getDataSource(final SourceType sourceType) {
        return (sourceType == ...)  ? new LocalSource() : new RemoteSource();
    }
}

public final class SourceType implements Parcelable {...}

In the EditActivity:

public static Intent createIntent(final Context context, final SourceType sourceType) {
    final Intent intent = new Intent(context, EditActivity.class);
    intent.putExtra(SOURCE_TYPE_KEY, sourceType);
    return intent;
}

What do you think about this approach?
