I tested the app (all good) and added this new version of the project to GitHub. Today I also registered the domain name for when my app is ready to sell on the Google Play Store. Sun 12 Aug 2018 at 12:18 PT I have competed  up to and including Lesson 2 Concept 22. Now starting Concept 23 – Custom Class resuming Monday 13th August 2018.  Tuesday 14th August, before continuing on the course, I’m studying the sample course: ud839_CustomAdapter_Example

and started my own Android notes, to help me keep track of the Android terminology and operation of Android apps.  Thu 16 Aug 2018 completed lesson 2, then cloned the GitHub code for (completed) ud839 Lesson 3 to Android Studio (see my Android Notes on how to do this), and started on ud839L4 (Images and Visual Polish)….

Then the Big Nerd Ranch textbook course.

This is where I’m at right now (Mon 28 May 2018) with my Android studies…

I hit a brick wall here:

on Lesson 1 Part 4 – “Import an Existing Project”.

The project I imported would not run. I need to do more research and figure out how to fix it before I can continue with that lesson.

Connecting the LG G3 phone device to Android Studio

USB Debugging Mode – LG G3. If you need to facilitate a connection between your device and a computer with the Android SDK (software development kit), view this info. If Developer Options are unavailable, navigate: Apps > Settings > About phone > Software info then tap Build number seven times.

If Developer Options are unavailable, navigate: Apps > Settings > About phone > Software info then tap Build number seven times.
  1. From a Home screen, navigate: Apps > Settings > Developer options.
  2. Ensure the Developer options switch (located in the upper-right) is turned on .
  3. Tap USB debugging to enable or disable.

5th April 2018 – Android Studies Checkpoint (started UD839) Imported an existing project (seemlessly).

Started the above today. Importing the Miwok project went seemlessly…

  1. Go to this GitHub project repository link.
  2. Click on the “Download zip” button to download the app code.
  3. Unzip the downloaded file on your computer so that you have a “Miwok” folder.
  4. Open Android Studio.
  5. Choose File > Import Project and select the “Miwok” folder. It may take some time for the project to be imported. If you have any issues, check the Troubleshooting document.
  6. Once that app has successfully imported, run the app on your Android device (phone, tablet, or emulator). It should look like this screenshot. Nothing happens when you click on any of the categories. That’s expected.

Just for your information, during the process of importing the project, Android Studio prompted for some updates and gave warnings related to obsolete features being replaced. This is due to the fact I am using the bleeding edge version of Android Studio, and the project I’m importing was written months previously.  So it took a few minutes to complete the updates and build, the installing the APK to the phone took minutes instead of the seconds it has taken so far with my apps. Nevertheless, all went seemlessly (if slowly) and the app ran as described on the phone.

How to shut down a Raspberry Pi running androidthings

Assuming the RPi3 running the androidthings image was connected to the internet at IP address, then to connect a laptop on the same network to the RPI3 running androidthings, and then shut down the androidthings RPI3, do the following: (note the -p means power off)
