3. Android Comprehensive open-source platform for mobile devices
Owned by Open Handset Alliance
Championed by Google
Stated goal: "accelerate innovation in mobile and offer consumers a richer, less expensive, and better mobile experience."
Chrome OS and Android merge.

4. Vision for Android
Hardware divergence or fragmentation, but it seems be holding together.

5. Android is NOT just phones
Tablets
Readers
Televisions
Game consoles
AR-Devices
Android Wear
Android is open-source, which means any manufacturer of mobile devices can drop Android onto it.

7. Android Version Distribution
Using the compatability (support) libraries, you can develop in 4.2 and min-build-target to 1.6.

HTC: has almost as many developers in Taiwan working on SenseUI as the Android team. Very sophisticated consumer device. Held up by Apple by injunction. .

10. Open Handset Alliance Headquarters: South Korea
The OHA was established on 5 November 2007, led by Google with 34 members including mobile handset makers, application developers, some mobile carriers and chip makers.
Android, the flagship software of the alliance, is based on an open source license and competes against mobile platforms from Apple, Microsoft, Nokia (Symbian), HP (formerly Palm), Research In Motion, and Samsung Electronics (bada).

11. Google has announced that there are now 700,000 apps available for Android. This means that for the first time, the number of apps available for Android customers matches those for iOS, according to Bloomberg. They're both around 700k available apps currently, and Google play is projected to make it to the 1m mark before Apple. These are global sales.

17. Intel losing market share to tablets and phones

18. Android Support three different processors: ARM, Intel, and MIPS.
The Intel or x86 chips are fast but they’re power hungry. They’re used on laptops. (Complex Instruction Set Computing or CISC)
The MIPS are used in embedded systems.
The ARM are RISC or (Reduced Instruction Set Computing). Much less power hungry chips.

19. The market for mobile software is exploding
The market for mobile software is exploding. Not just consumer; any company that has agents distributed in the field will benefit from this. You think of consumers playing games, but many applications are field-force automation. Developers make money B2B. Consider medical professionals like medical doctors which move from hospital bed to hospital bed. Sales people typically qualify you when you walk into a car showroom.

The slide the google doesn't want you to see.

22. Android Architecture

23. 6/9/12

24. Stock apps, all of which can be replaced; modular architecture.
Managers (APIs to OS). You will use these APIs in your apps.
SQLite and WebKit are in iOS as well. libc is from c. OpenGL is graphics, etc.
Software Stack:
Linux Kernel - not another flavor of linux like cent-os.
Well known driver model
Linux security is excellent - and Android entrusts it's security to linux
many open-source projects, including sqlLite, which is a very small relational database
webkit, which is what iOS also uses for webviews, including it's client, which is just a webkit webview.
surface manager is for rendering graphics, FreeType is likely royalty free type-fonts,
Dalvik VM - compiles to java byte-code, then to dalvik byte-code, which is even tighter than java byte-code. (oracle lost it's case against google, which is good).
each application is running in seperate Dalvik VM instance. The apps communicate using something called intents intra-app and inter-app both.
Core libs including Activity and Bundle and Intent
Package manager like in Linux, manages the applications (called packages in linux) on your device. Telelphony is phone, location is GPS, Content providers are data stores.
Built-in Applications that come with the operating system.
kernel components; you won't touch these.

25. Java byte code versus Dalvik byte code
Java byte code versus Dalvik byte code. The byte code is even tighter and is optimized for Mobile.
android dex files are like java class files - they're bytecode, but they've been optimized for a resource constrained environment.

26. Android is modular
Android architecture is extremely modular and open. If you don't like your mail-reader, you can get a 3rd party one. If you don't like your text-client, you can get a 3rd party one, or you can make your own. Extreme decoupling.

28. Building Blocks of an App
Activities (you can see an activity, activities have views.)
Intents (shuttle messages)
Services (background services)
Content Providers (api abstraction to datastore)
Broadcast Receivers (capture OS broadcasts; such as battery-low, reboot, sms-received, headphone-plugged-in, etc. )

Android Layouts explained
The Layout file is nothing more than XML with some Android namespaces: xmlns:android
declaring-layout.html
Search for TextView or EditText or Button

33. Views versus ViewGroups
Views versus ViewGroups
All Views and ViewGroups are Views. View is the Grand-daddy of all Views in Android which itself is just a Java Object.
ViewGroups collect Views and other Viewgroups. You can nest ViewGroups.
Typical ViewGroups: LinearLayout, RelativeLayout, FrameLayout.

:layout_gravity descibes how the view is layed- out inside its parent. (outside)
:gravity describes how the view lays out its elements or children (inside)

41. Projects

42. Download and install required software:
Java SDK (7):
Android Studio: developer.android.com/sdk/installing/studio.html
Git: git-scm.com
SourceTree:

43. GIT architecture

44. git config --global user.name "Your Name"
git config --global user.

45. add/reset/commit:
move files from working-dir to stage-dir(aka index)
git add .
git add res/.
git add src/.
git add res/values/strings.xml
move files from stage-dir(aka index) to working-dir
git reset HEAD .
git reset head res/.
git reset head src/.
git reset head res/values/strings.xml
git commit -m “your commit message.”

46. Amending:
Every commit is associated with a sha-1 hash. That hash is derived from 1/ the file changes in that commit and 2/ the previous commit.
You can not change any commit unless that commit is at the head. Since no other commits depend on the head, you may safely change the head.
To change the head, use
git commit --amend -m “your message”
git commit --amend --no-edit

47. Branching:
To list the branches in a project:
git branch
git branch -r
git branch --all
To create a branch:
git checkout -b branchName c39b
git checkout -b branchName
To delete a branch:
git branch -D branchName
To checkout a branch:
git checkout 7afe
git checkout master

48. Pushing to remotes:
To see the remotes:
git remote -v show
To push to a remote:
git push origin master
git push --all
To clear all local changes since last push
git reset --hard origin/master

49. Reverting (does the exact opposite)
git revert 0da8 --no-edit
git revert head --no-edit
git revert head~3 --no-edit
To clear all local changes since last push
git reset --hard origin/master
To delete a remote branch
git push origin :branchName
