04 May 2015: Took one week off to port my Java game to Android (50% of my time), hobby electronics (25% of my time) and German improvement (25% of my time). I started with Developing Android Apps course but made no progress due to technical difficulties:
06 May 2015: Started using KanbanFlow.
Android: Android Studio emulator still not working, still not recognizing Nexus 10. Tried to build unsigned apk, success! Realized that my laptop does not recognize my Nexus 10. Installed universal adb driver, disabled USB debugging on Nexus, success. Copied apk to Nexus via USB, install, success. I still cannot see my real Nexus 10 on Android Studio. I might need a better computer. Main source of video lectures: Android Studio Tutorial by Derek Banas.
German: Two practices on Duolingo (20XP)
Electronics: Managed to control a DC motor.
07 May 2015:
Android: Wrote an app that counts from 0 to 9 with 500ms delay. I first tried Thread (which is usual for desktop Java apps), but Nexus said "the application stopped". Then I used postDelayed and finally it worked. This means that my existing Java library knowledge is not of much use, I have to learn new libraries. My tiring workflow was (without any debugging capability):
- Android Studio is painfully slow on my laptop, Samsung ATIV Book 9 Lite (NP905S3G). Specs: Windows 8.1, Quad Core 1GHz, 4GB RAM, 40GB free disk space.
- When I tried to use the emulator, I got "ERROR: x86 emulation currently requires hardware acceleration". Tried to install Intel HAXM, got "Computer does not support Intel Virtualization Technology (VT-x)". Checked BIOS, VT-x was enabled.
- Plugged in my Nexus 10, Android Studio did not recognize it.
- I don't know what else to do.

My tiring workflow was (without any debugging capability):
- Work in 25 minute blocks.
- Build app (~2min the first time, ~30s afterwards)
- Copy apk_debug.apk to Nexus.
- On Nexus install apk_debug.apk.
- Run apk_debug.apk.
- Repeat until you get what you want.
