6. Deliverables

• Every week you will get homework and you are supposed to compete the work before the next lecture.

• Deliver your work to creativeapps.submission@gmail.com, with your full name in the subject (so that we can find all your work later easily).

• Deliver your work always in one ZIP file attached to your email.
• You don't have to deliver every week. It can be delayed, until one week after the last lecture.

7. Installation

7.1. Android Studio installation

• If you are asked to install JDK first:
  • check if you have earlier versions of JRE or JDK installed. Uninstall previous versions.
  • download the latest JDK for your system (32bit or 64bit).
  • quit the installation program if it still running.
  • restart the installation.

7.2. Start Android Studio

• if you see this message, do not panic, do it accordingly.

  • 

• you might need to install build tools:

  • 

7.3. CPU acceleration status

• if you see the message below when starting the android emulator: In the configuration of the virtual device you need to use ARM cpu instead if the intel one. If you cannot find ARM in the list of choices, you might have to go back to SDK manager to install relevant packages.

  • 

7.4. ANDROID_AVD_HOME

• When starting the android emulator, if it complaints that it can not find the <name of the AVD>.ini in "ANDROID_AVD_HOME" or "HOME" locations:

  1. find out where your ANDROID_AVD_HOME actually is. In AVD manager, select the AVD, then press the button "Details". In the picture below, the path in the red ellipse is actually where ANDROID_AVD_HOME should be.

     • 

  2. Go to Control Panel\System and Security\System, then Advanced system settings, Advanced, Environment Variables, in the lower part of the dialog box about "System variables", press "New..." or if the ANDROID_AVD_HOME exists, press "Edit", make sure it looks like the following. Note: you have to fill out what is actually your ANDROID_AVD_HOME from Step 1.

7.5. An alternative emulator

• If you are fed up by the slow emulator, you may want to try this one:

7.6. How to speed up the emulator

Thanks to Sven Ebens.

• need an intel chipset, that supports VT-X
• need to enable virtualization technology (or simular) in BIOS
• snapshot is not necessarily faster, because it still takes basicly the same time to boot, but you get to continue where you left off
