Androidのエミュレータ（AVD＝Android Virtual Device、バーチャル携帯電話）をスタートからエラーがいっぱい出たので大変だったけど、すでにJavaの段階に進歩ーすることができた。つづく。。。
Last week I downloaded Android Studio version 3.1.1. Playing
around with an app builder for the second time ever (I’ve tried a couple of online
app builders such as Andromo) I looked at a video called Android Studio for
Beginners part 1, by Bill Butterfield, on YouTube. Was able to install it with few
issues (except for making a donation to eclipse which turned out to be unnecessary, argh),
then with much pausing of the video, drag/drop the elements of the practice
app. Trying to run the app using an Android virtual device (AVD) was the longest
part so far, it generated so many errors. I’m only halfway through the video!! Finally after getting the
emulator to work, I’m now working on the part of the video where Bill writes the —
wait for it — actual Java code. To be continued…
