Android Studies – where I’m at on Thu 30th Aug 2018

I’m at this position in my Udacity studies: ud839 L5 (Activity Lifecycle and Audio Playback). In my Google researches I found a set of developer videos…

Android Developer Fundamentals - Videos

and started to go through them from the first. To date I am on video #6 out of 68 videos. Then I started to plan my quiz2exam app. The initial plan is to read a formatted text file of quiz or exam questions (with answers and categories) into a SQLite database and allow simple display on the phone. I acquired quiz2exam.com to promote and sell my  Quiz2Exam app when it is finally done.  I created the app Quiz2Exam to do my development on.  I’m continuing to update my Android Notes where I’m adding useful information as I find it.

My current focus is on how to read a text file into SQLite through an Android app.

Android Studio – courses completed so far… Fri 17 Aug 2018 at 14:13 PT

Android Basics: User Interface (completed Sat 24 Feb 2018) – https://classroom.udacity.com/courses/ud834

Android Basics: Multiscreen Apps (started Mon 2nd April 2018) on  Wed 8th August 2018 I have completed up to and including Lesson 2 Concept 16 – everything runs fine at this point so saved project to GitHub and start on Concept 17 https://classroom.udacity.com/courses/ud839  I have completed up to and including Lesson 2 Concept 17 – everything runs fine at this point so saved project to GitHub and start on Concept 18.  All good but in Lesson 2 Concept 19, the code example in the video shows data in the GridView (Miwok words for each number word), but we haven’t been instructed to type them in yet… Also on Fri 10th August I changed the manifest file for the new app name “quiz2exam” instead of “miwok”, and added ic_launcher.png files for the new question mark (?) icon. I tested the app (all good) and added this new version of the project to GitHub. Today I also registered the domain name quiz2exam.com for when my app is ready to sell on the Google Play Store. Sun 12 Aug 2018 at 12:18 PT I have competed https://classroom.udacity.com/courses/ud839  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)…. Completed ud839L4 (Images and Visual Polish)…. at 2pm on Fri 17th Aug 2018.  Starting ud839  L5 (Activity Lifecycle and Audio Playback)….

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

I hit a brick wall here:

https://classroom.udacity.com/courses/ud839

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.

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

https://classroom.udacity.com/courses/ud839

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.

Getting started learning how to develop Android Apps

After previously installing Android Studio (a stable version and also the bleeding edge version), I studied the following document (as much as I needed to get started):

https://developer.android.com/studio/intro/index.html

The above document I finished today. Then I started on the following document to learn how to get started developing Android apps:

https://developer.android.com/guide/index.html

I will continue using the document above, going through every section in order, then go on to the therein suggested Udacity videos.

I’m also using this book:

https://www.bignerdranch.com/books/android-programming/

But will start the above book (it needs your full attention) after completing the following Udacity video courses…

There are many more Android Development courses at Udacity which I will take after completing the Big Nerd Ranch textbook course.
