# This script install Android sdk and ndk.

# It also runs update for SDK API level 21, latest SDK tools, latest platform-tools and build-tools version 23.0.3

# Build-tools version 23.0.3 is the latest usable version for Red Hat 6. Newer version of build-tools, version 24.x.x, requires GLIBC_2.14, which is not available in Red Hat 6.

# Android 16 is the minimum requirement for Qt 5.7 applications, but we need something more recent than that for building Qt itself.
# E.g The Bluetooth features that require Android 21 will disable themselves dynamically when running on an Android 16 device.
# That's why we need to use Andoid-21 API version in Qt 5.9.
