Hey, it was nice working with you all. I plan on going through this book next. If there's interest in collaboration, and maybe splitting the cost of an e-book, let me know.

I was asked to upload a file of the audio from the previous meeting.  This forum requires upload to YouTube, which requires a file format I have not been ale to create yet.

I will be at Church this Thursday for Maundy Thursday, part of Holy Week leading to Easter.  Back to the Jam the next Thursday.

As second prize, here are some notes from 3/19.  It would be great if someone could take and post the best possible notes for this Thursday.  An audio tape would be even better.

Suggestion that we will find Kayak or KIAC.  [Spelling uncertain.  Sounds like KIAK.]

V7 has material for action bar

Google captures good data about who is using what version of Android

Developer counsole user --- Kitkat to make fit into smaller versions
Majority of developers currently writing in Jellybean and Kitcat. 41% developing on Kitcat.
Seems should currently go with api 15 or 16 at conclusion of the discussion.

swiping is expensive in terms of resources
Therefore use newer device with more power


7:57 Swipe somewhat replaces action bar:
Try Navigation Drawer
Leaves more screen real estate.
Goes in layout folder rather than xml
8:03 Contacts menus pop up when hold finger to a a particular spot on screen.
double taps, 2-fingers, combinations for gestural choosing.

Naimi Djouhri had a lot of good questions and comments

Beth says Android has the most market share in US

ISPs control the market for iPhone and Android phones
Limitations on data transmission a problem
Blackberry opened the door for ISPs to share data openly
In India they pay per byte for data trnasmission. 
Leads to a completely different user psychology re data.

Bada is low end O.S. by Samsung popular in W.Europe
Google wants more bandwidth, because more ads --> more revenue

Do half of lesson 5 for next week.

I am having a hard time with the "Action Bar" step of lesson 5.

First, I was not able to use "@style/Theme.AppCompat.Light.DarkActionBar". So I included the library 'com.android.support:appcompat-v7:20.0.0' and downgraded the target SDK to 20. 

But now I am not able to define the node '<item name="colorPrimary">@color/sunshine_blue</item>', as I get an error which states: "Error:(5, 21) No resource found that matches the given name: attr 'colorPrimary'".

Perhaps I need to update my SDK? Has anybody else run into this issue? I'm sure it's not a huge deal, but it is frustrating none-the-less.

I am jarred by the shortfall in consistency in the videos.  Here is an example.

ForecastAdapter.java originally has this line:
 double high = cursor.getDouble(ForecastFragment.COL_WEATHER_MAX_TEMP);
Then in "Modify ForecastAdapter-Solution"
it changes to 
 float high = cursor.getFloat(ForecastFragment.COL_WEATHER_MAX_TEMP);

It then returns to double here:
https://www.udacity.com/course/viewer#!/c-ud853/l-1623168625/e-1667758593/m-1667758594

Which are they proposing to teach us that we use, and on what basis?

One line of pedagogical logic is that these kinds of changes without explanation or warning force the student to learn the material better.  Valid point. We do a lot of debugging of our own typing, and we can also debug Udacity.  Another holds that time is precious and we are attempting to process a lot of material per week, so seeming glitches in the teaching material poses a problem.  This would argue that Udacity needs to put some more effort into debugging its materials.

I think that the other half of why to type in our code is that it gets us used to using Android Studio which has awesome features for reducing typos and making sure as much as possible is consistent across the application, thus helping to free our attention to the substance of coding.

Thinking about the apps that I have, human factor design is essential, but the functionality is more important.  I refuse to use Facebook app because it downloads way too much data, making it costly and slow.  I really like apps that give me some arcane pieces of information, such as arcane gps info.  I get very irritated when one of my errant fingers brushes against some part of the screen and creates major damage.  I find the android typing function primitive and cumbersome.  I itch for Droids to reach their full promise.

It's beyond the scope of this course, but I found an interesting tutorial on building a RESTful web service using Spring. I haven't actually tried this out yet, but I'm sure that as with all things it's easy when simple and difficult when the use case becomes more complex:

Hi Folks - here-s what +Jinn Kim  has outlined for tonight's Study group meetup.

here is an outline of what i plan on talking about.


app can be killed anytime for resouces

activity lifecycle
onCreate -> created
onStart -> visible
onResume -> active

onPaused -> Paused
onStop -> Stopped
onDestroy > Destroyed

active
foreground and infoocus

active -> visible -> background

app roatation
onPause, onStop is where resources should be released
sensors, location, broadcast recievers, heavy CPU/GPU (games)

exit and quit dont' do anything


onCreate -> onRestoreInstanceState -> Active ->
onSaveInstanceState -> onpaause -> terminated


storage
sharedPreferences
key value pairs of primatives
SQLite DB
ContentProvider
DataContract
SQlite DB
DB helper
testing
Junit asserts
