I recently developed my first appwidget for Android, and it works really nice. I basically created a collection widget and use a Loader to retrieve the data from a database, and when a user clicks on the list item, that items details will be saved into a bundle in an intent, and the main activity will be launched with the bundled info displayed to the user.My code works as intended; however, I am concerned with possible edge cases in how widgets actually work, initialize, and update that I have not thought of. Again, I am new to widget development, and the API for widgets took a lot for me to wrap my head around. Question ObjectiveWhile any code review is helpful, I am basing my question on the premise set up here to answer #1 and #2 from the reviewer's point of view:Does this code actually do what it is supposed to do under normal conditions?Are there edge cases where this code will fail?This GitHub link links directly to my Hub Flavor that implements the appwidget (Java and res folders, and manifest file).App Widget Providerpublic class ResumeHubWidgetProvider extends AppWidgetProvider {    private static final String LAUNCH_RESUME_ACTION = io.github.ciscorucinski.personal.intro.hub.LAUNCH_RESUME_ACTION;
