Android Room database persistence library examples

As a note to self, here are some Android Room database persistence library examples:

• Building database with Room Persistence Library
• A new approach to store data

Those tutorials don’t show how to properly use Room database access methods, so they’ll lead to Android “Application Not Responding” (ANR) errors. Therefore, here are some related Google/Android docs:

• Keeping Your App Responsive (ANR)
• ANR Rate
• AsyncTask
• StrictMode (a little like lint for Android)

Finally, here’s my own Android AsyncTask REST example, which also shows how to use an AsyncTask.
