How to set or change the default Java (JDK) version on OSX (Mac)?

First of all check current java versions, run following command in the terminal

/usr/libexec/java_home -V

which will output something like the following:

Matching Java Virtual Machines (2): 9, x86_64: "Java SE 9" /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home 1.8.0_152, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home

Setup Android SDK on OSX with and without the android studio

Hi, I am a fork from https://gist.github.com/patrickhammond/4ddbe49a67e5eb1b9c03.

A high level overview for what I need to do to get most of an Android environment setup and maintained on OSX higher Catalina and Big Sur with and without Android Studio been installed.

Considering the SDK is installed under /Users/<your_user>/Library/Android/sdk folder which is the Android Studio preferred SDK location, but it works fine under /usr/local/share/android-sdk as well, which is a location pretty much used on CI mostly.

Prerequisites:

How to manually self-size UITableView tableHeaderView/tableFooterView in iOS 11
// For the best results, your tableHeaderView/tableFooterView should be a UITableViewHeaderFooterView with your content inside the contentView.
let tableHeaderView = UITableViewHeaderFooterView()
let fittingSize = CGSize(width: tableView.bounds.width - (tableView.safeAreaInsets.left + tableView.safeAreaInsets.right), height: 0)
let size = tableHeaderView.systemLayoutSizeFitting(fittingSize, withHorizontalFittingPriority: .required, verticalFittingPriority: .fittingSizeLevel)
tableHeaderView.frame = CGRect(origin: .zero, size: size)
tableView.tableHeaderView = tableHeaderView
// When you set this view to the tableHeaderView/tableFooterView on the table view, the table view will preserve the existing size of its frame.
// If you need to change the size, remove the tableHeaderView/tableFooterView, set a new frame on it, then re-set it on the table view again.

Raspberry Pi and Thunderboard help

Thunderboard Setup

I had a very difficult time following this tutorial so I am writing this to help me and other people. I would recommend following the directions in the tutorial using this page for reference if things go wrong.

I did this whole process on my Raspberry Pi 3 with Raspbian OS.

Following the GitHub doc

First things first: clone the repository.

git clone https://github.com/SiliconLabs/thundercloud.git
