The Android Apps – Phone Calls and SMS course includes two lessons created by the Google Developer Training team. The lessons are designed to be used in instructor-led training, but the materials are also available online for self-study.
The course materials include the conceptual lessons and practical exercises in this GitBook. Slide decks are also available for optional use by instructors.
In Android Phone Calls, students learn how to use the telephony features in Android. In the practical, they create an app that launches the Phone app with a phone number to make a call, and another app that checks for needed permissions and services, and then lets the user make a phone call from within the app.
In Android SMS Messages, students learn how to use the SMS features in Android. In the practical, they create an app that launches an SMS messaging app with a message, and another app that checks for needed permissions, sends an SMS message, and receives SMS messages.
