Assessment of Students' Solutions:

Laboratory Tasks:

Laboratory (A0)  -  ANDROID - Introduction, Eclipse IDE + Android SDK
Getting familiar with Android platform and its Integrated Development Environment.
  1. Use SDK Manager to check/install/uninstall  Android SDK ( platform, samples, tools, documentation, etc.) for selected API version (default: API 2.3.3 Gingerbread)
  2. Use Virtual Device Manager to create Android Emulator for API level (version) installed in the exercise (a)
  3. Test the proces of creation / building / running of Android sample applications:
    File > New > Other > Android > Sample Project > SkeletonApp
    or more complicated APIDemos sample projects.
    Utilize virtual device created in exercise (b).
  4. Use DDMS perspective and its windows: Devices, FileExplorer, Emulator control and LogCat, to explore the state of emulator and test your SkeletonApp application.
Supplementary readings - slides by Victor Matos from Cleveland State University:
       - Android Development Tools  (file Chapter02-Setup in archiwes ZIP )

Laboratory (A1.a)   -  ANDROID  - Understand Activity Life Cycle.
Download, unpack and open example code 03-1-LifeCycleDemo from V.Matos archives,
or try to create your own version of such Android application, signaling changes of internal state through notifying Toasts e.g.
      Toast.makeText(this, "onCreate", 1).show();
implemented for all following events:  onCreate, onStart, onResume,
onSaveInstanceState, onPause, onStop, onDestroy, onRestart.

This task could be simplified with the use of
 Menu > Source > Override/Implement Methods…
option from the Eclipse’s top menu.

Observe and note the sequence of messages displayed by the Toast-commands after:
  1. Click on application FINISH button
  2. Click on the emulator’s HOME button
  3. Click on the emulator’s CALL ( Green phone)
  4. Long press on the emulator’s HANG-UP button
  5. Receiving a text-message from other emulator
  6. Making a voice-call from other emulator.
Every time, return to the same "running" state, through clicking on device's launch pad,
and selecting your application icon.

Supplementary readings:
       - Android Application's Life Cycle  (file Chapter03-Life-Cycle in archives ZIP )
Laboratory (A1.b)   -   ANDROID - Creating example Currency Converter app.
  1. Follow instructions from lecture slides Android Devlopment Introduction
    (file Chapter01-Intro in archives ZIP , pg.33-41)
    to create new Android project and implement single activity "Currency Converter".

  2. Use DDMS perspective to test and debug internal state of emulator and your Currency Converter application.

Laboratory (A2)  -  ANDROID - Experiments with UI design
Create single screen/activity application demonstrating the use of:  Layouts, Widgets, and Menu components to compose the user interface:
  1. Implement a program demonstrating various possibilities for changes in the color, size and font style (of the displayed TextView content), as a result of pressing different buttons or selecting various menu options.
  2. Create your implementation of a general-purpose mathematical calculator.
  3. Develop some kind of multiple-choice e-learning application, that supports memorizing the correlation of predefined number of word-pairs, in two different languages (e.g. Polish and English)

Laboratory (A3)  -   ANDROID -   Intents and multi-screen apps
Create a multi-activity application demonstrating the use of Android's Intents
to start another activity or build-in Intent handlers (platform provided applications) like: Contacts, Phone Dialer, Web Browser, Google Map, etc:
  1. display the phone contacts list (and receive the data of the selected contact),
  2. send an SMS message to selected receiver,
  3. display google map of the place with the given geographic coordinates (latitude/longitude),
  4. display an “About” screen and return the data bundle containing student's name, email and the version number of the application.
At least one of sub-activities have to be self-made by the student.
At least one of them must return back some results to the launching code.

Supplementary readings:
  - Android Intents - Tutorial (by Lars Vogel)

Laboratory (A4)  -   ANDROID  -  Telephony API
Create "TelephonyDemo" application which provides options for:
  1. gather basic information about the phone state (CallState, PhoneType, NetworkType, subscriber SIM ID, etc)
  2. block all outgoing voice calls to specified phone number,
  3. react to an incoming SMS, automatically sending back another SMS with the name of student (and phone position?) added to the message body.
  4. monitor / listen to phone state changes (ie. the availability of data connection or changes of signal strength)
Supplementary reading: Chapter 7. Telephony API


Laboratory (A_Project)  -   ANDROID -  advanced application
  • Theme of final Android project may be proposed by student.

  • Each student selects at least two of mobile technology aspects
    (which are not included in laboratories A0 - A4):

    3. networking, data synchronization or web services
    4. 3D graphics or animation on mobile device
    5. Bluetooth communication between mobile devices
  • Students use the period of three laboratories assigned to this project,
    to create entirely individual mobile application,
    that demonstrates selected technology aspects.
