Installing NativeScript on Windows
This is a step by step tutorial covering all the aspects of Installing NativeScript on Windows Machine. The NativeScript on the windows machine can be used to develop apps targeted Android Platform. To target IOS platforms you need to install XCode, which is not supported in the Windows.
NativeScript needs only Windows 7 service pack 1 or later, the Android emulator requires a minimum of 3 GB RAM an 1280×800 screen resolution. I recommend a Minimum RAM of 8 GB for faster development experience
- Windows 7 Service Pack 1 or later
- 3 GB RAM minimum, 8 GB RAM recommended.
- 1280 x 800 minimum screen resolution
- 64 bit OS recommended
- Disable Hyper-V Manager (if you are using Android Emulator)
The NativeScript requires us to install the following components
- NativeScript CLI
- Visual Studio Code
- Android SDK (We will install Android SDK via Android Studio)
The first step is to install Node.js. You can check if the Node.js is already installed by using the following command.
If Node.js is installed it will report the correct version, else you will see a message like one above. The current version of Node.js is 8.11.3. You can check the latest version available from the link.
If Node.js is not installed or lower version is installed then you can download and install it.
You can download the Node.js from the following Location https://nodejs.org/en/download/
Double clicking on the Downloaded file begins the installation. The Installation wizard takes you through the initial welcome screen & license agreement screen.
Next, it will ask you where would you like to install the Node.js.
Next, it will let you choose the components to install. The npm package manager is also being installed along with the Node.js.
Clicking on the next will take you final confirmation screen and then the installation begins.
npm Package Manager
The Node.js also Installs the npm package manager. We are going to use npm to install Angular, Typescript, web pack and any other packages/modules required by our application.
The latest version of the npm package manager is 6.2.0. You can find out the latest version from this link.
The version of the npm installed in your PC can be found from the following command.
If you have an older version of the npm, then you can upgrade it with the following command.
npm install -g npm@latest
The Java Development Kit (JDK), officially named “Java Platform, Standard Edition (Java SE)” is needed by Android SDK and Emulator. Hence we need to install it first.
The latest version of JDK is 10 (only 64bit available). The JDK Version 9 is not supported any more.
I Recommend to use the tested and tried JDK version 8.
Downloading JDK 8
The JDK 8 can be downloaded from the link. You need to scroll down and select JDK 8.
Click on download link will take you to next screen, where you are asked to Accept the license agreement before downloading either 64 bit or 32bit version.
Installing JDK 8
Double click on downloaded file to start the installation. After the welcome screen, you are presented with the custom setup screen. Note down the install location.
Click on Next button, will start the installation. Once the installation is complete, the installer installs the JRE Components. Accept it and continue to install JRE as well.
JAVA_HOME Environment variable
The next step is to set up the JAVA_HOME variable to point to the installation directory. We noted down the Installation directory in the previous step, which is in the C:\Program Files\Java\jdk1.8.0_bxx folder where bxx is the update number. Follow the following Steps.
- Go to Control Panel -> System ( or Control Panel -> System and security)
- Click on Advanced System Settings
- Under Advanced Tab Select Environment Variables
- Under the System Variables tab ( in the bottom pane) check to see if JAVA_HOME is available. If found double click on it or else click one new
- Enter Variable Name =JAVA_HOME & Variable Value=C:\Program Files\Java\jdk1.8.0_181.
- Click on OK when done.
Check the JAVA_HOME Variable
Open the command prompt ( if the command window is already opened, then close it and reopen it and type the command Set JAVA_HOME as shown below.
If everything is done correctly you should see the JAVA_HOME return the correct path to Java SDK
The NativeScript command line interface or NativeScript CLI lets you create, build, and deploy NativeScript-based projects on iOS and Android devices
Installing NativeScript CLI
We will use the npm package manager to install the NativeScript CLI. Open the Command window and run the following Command.
npm install -g nativescript
The installation is simple and asks few questions and completes.
Visual Studio Code
We need a code editor to create our Code. The best editor is Visual Studio Code. You can choose any code editor of your choice
Downloading Visual Studio Code
Download it from this Link and install it.
Installing Visual Studio Code
Double click on the downloaded installer to begin Installation and keep clicking on next/yes button until it finishes.
The best way to install Android SDK is to install the Android Studio, which will install the required SDK and comes with GUI tools to create and Manage Android virtual devices & emulators.
Android Studio is IDE for developing Android apps via JAVA and it is freely available under Apache License 2.0.
Downloading Android Studio
The Android Installer is available only for the 64bit version. For 32bit you need to download the zip file. You can download it from this link.
Installing Android Studio
For 32 bit Windows
Follow these steps to install Android Studio in 32 bit Windows.
- Go to C:\Program Files.
- Create a folder named Android.
- Unzip the downloaded Zip file.
- Copy the folder Android-Studio from the unzipped file to the folder C:\Program files\Android.
- Rename the folder from Android-Studio to Android Studio.
- Now go to the folder C:\Program Files\Android\Android Studio\bin.
- Locate the Studio.exe and create a shortcut in the desktop.
For 64 bit Windows
Double click on the downloaded installer to begin the Installation Process. After the welcome screen, you will be presented with the option to choose the component.
Select both the option and click on Next.
Next, you are asked to choose the location. Accept the defaults and click on Next to continue.
In the next window, you are asked to select the start menu folder. Accept the defaults and click on Install to begin the installation. Once completed you are directed to the installation completed screen.
From this point onwards the 32bit & 64Bit installation procedures are the same.
Common for both 32 & 64bit OS
Start Android Studio.
When you Start Android Studio for the first time, it will ask you to Import the Studio settings. Since this is a fresh install select do not import settings and click on OK.
The Android Studio will download a few components and then displays the Android Studio Setup Wizard dialogue box.
The first screen is the welcome screen. Click on Next to continue.
The second dialogue box asks for the install type. Select the default i.e. Standard and click on next to continue to next window.
The next up is select UI Theme dialogue box. Again Accept the default to continue.
Finally, the Verify Settings dialogue appears. Click on Finish to complete the Wizard
Now, the Android Studio setup wizard starts to download the various components etc and installs them in the system. This will take time depending on your internet connection.
You may see an error here.
- If the processor is non-intel based.
- If you have not disabled Hyper-V Manager, then the Intel® HAXM installer will fail.
Ignore those and continue.
Finally, when the installation is finished, your presented with the Welcome to Android Studio screen as shown below. At this point installation of Android Studio is complete.
But, Android Studio will not open until you create a new project or open an existing one. Hence we will create a new project. Click on Start a new Android Studio Project.
The Create New Project wizard now starts running. In the first window accept the defaults and click on next.
The wizard will now open Target Android Devices, again accept the defaults and click on next.
Add an activity to Mobile is the next option. Accept defaults and continue.
Configure Activity is the next window. Click on next.
Component Installer is the last window. Click on Finish
Android Studio may start a few more downloads. Wait for it to finish. Once the download is over the new project is created and you are taken to the Android workspace.
Check for the AVD Manager & SDK Manager option under the tools menu as shown below. In the older version of the Android studio you will find this menu under the Tools -> Android.
It may happen that you may encounter the following errors
- Android Menu under tools is missing.
- Might see “Failed to find Build Tools revision xx.x.x” as shown below
- AVD Manager is greyed out
In such case click on the link provided to fix the error. This will download the required components.
Android SDK Manager
Open the SDK Manager by clicking on Menu Option Tools -> SDK Manager ( Tools -> Android -> SDK Manager).
At left-hand pane Select Android SDK.
At the top, you will see the location where Android SDK files are stored. You can click on the Edit button to change the location.
Note down this location as you need this in the next section.
Ths tab contains the list of Android SDK’s.
The Android SDKs are required if you want to develop apps targeting the Android Platform. Each new version of Android comes with its own SDK version.
SDK Tools contains the set of development and debugging tools for the Android SDK.
NativeScript supports API version 22 and above. Hence any version of API below 22 will not work with NativeScript.
It is also important to decide the target API while developing an app as the Apps targeting higher API levels will not work with lower API. Selecting the very low API level will also limit your options.
The correct way is to check the current usage of API, which you can find out from this link.
You can choose to install API Levels starting from 22 by clicking on Check Box next to the Android SDK as shown in the image above.
While you wait for the download to finish, you can set the ANDROID_HOME environment variable as shown in the next section.
ANDROID_HOME Environment variable
The last step in the installation is to create the ANDROID_HOME environment variable.
Note down the SDK Location from the previous section.
- Go to Control Panel -> System ( or Control Panel -> System and security).
- Click on Advanced System Settings.
- Under Advanced Tab Select Environment Variables.
- Under the System Variables tab ( in the bottom pane) check to see if JAVA_HOME is available. If found double click on it else click one new.
- Enter Variable Name =ANDROID_HOME & Variable Value=Path to SDK Location.
- Click on Save when done
Verifying the installation
Finally, verify everything is working ok by using the tns –doctor command as shown below.
The tns is part of the NativeScript command-line interface, which has many commands including how to create new apps, how to get those apps running on emulators etc.
That completes the installation of NativeScript and its related dependencies.
But before you start to create your first NativeScript mobile app, there is one more thing to do. I.e. Create Android Virtual Devices and configure it run on Android Emulator.
