Android - Android Studio
NOTE : I wrote this section on Nov 2017. You may see a little bit (or widely) different screenshots from what you see here depending on when you are doing the download.
As many other software, downloading Android Studio is very simple. But the downloaded package would not contains all the components that are necessary to fully utilize the Android Studio. This download is to get a kind of minimum set of packages for Android Studio.
Click here to go to the download page as shown below and click [DOWNLOAD ANDROID STUDIO]
Then you would see the license agreement window as shown below. Check the license agreement and click the download button.
As download progresses, you would see the installation guide video as shown below. It will show a short video tutorial for Android Studio Installation. (NOTE : Real installation would NEVER be as simple as shown in the video. This is why I wrote another page for the installation process)
