Android Studio, SDK and NDK on Linux laptop

In recent days, I installed the Android Studio, Android SDK and Android NDK on my Linux laptop named ‘Klystron’. Rather arbitrarily, I decided not to reinstall my Android-building capabilities on the Windows 7 Desktop ‘Mithral’, which were based on the antiquated practice of using Eclipse to build Android apps. It continues in the same vane it started in, with SDK updates.

But the approach of using Android Studio on the laptop suits me, instead of setting up Eclipse in this way again.

Also, I have had to install JDK 8 on the laptop, which under Debian / Jessie means we have to resort to backports. But that was a straightforward task to accomplish.
