Creating your First APK with the Cordova CLI - Part II
Diego Lizarazo Rivera
Sr. Developer Evangelist
In Part 1 of this intro to Apache Cordova series, we were able to see how front-end developers could use standard web technologies to create cross-platform mobile applications, and the prerequisites to install Cordova in your dev environment.
In this second part we are focused on creating your first application with Cordova, and how to publish your app in the Samsung Galaxy Store.
Creating the App
After installing Cordova, you should go to the file directory where you maintain your source code. There, you can create a Cordova project. This would be a simple Hello World project, but would give you an idea of the file structure of a Cordova project, and the different parts that you can modify to obtain the functionality you are looking for.
In your terminal or command interface type:
cordova create CordovaProject com.example.hello CordovaApp
- CordovaProject is the directory name where the app is created.
- com.example.hello is the default reverse domain value (package name). You should use your own domain name if possible.
- CordovaApp is the title of your app.
This creates the required directory structure for your Cordova app. By default, the Cordova create script generates a skeletal web-based application whose home page is the project's www/index.html file.
Since Cordova works for multiple platforms, we have to add Android to the build settings. You need to open your project directory in the command prompt. In our example, it is the Cordova Project. You should only choose platforms that you need. To be able to use the specified platform, you need to have installed the specific platform SDK.
All subsequent commands need to be run within the project's directory, or any subdirectories:
Add the Android platform, since this is the target of app, and ensure they get saved to config.xml and package.json:
cordova platform add android
You can also remove a platform from your project by using:
cordova platform rm android
To make certain you have added all the platforms you are targeting you can type:
cordova platform ls
This should list all the added platforms for your current project.
Checking the Install pre-requisites for building
To build and run apps, you need to install SDKs for each platform you wish to target. Alternatively, if you are using browser for development you can use browser platform which does not require any platform SDKs.
To check if you satisfy requirements for building the platform that you just added:
This command should show you a result similar to this one:
Requirements check results for android: Java JDK: installed . Android SDK: installed Android target: installed android-19,android-21,android-22,android-23,Google Inc.:Google APIs:19,Google Inc.:Google APIs (x86 System Image):19,Google Inc.:Google APIs:23 Gradle: installed
Building the App
This step builds the app for a specified platform so we can run it on mobile device or emulator.
If you have added more than one platform to your project, you can limit the scope of each build to specific platforms. For our example we should add 'android':
cordova build android
Build for android platform in release mode and use the specified build configuration:
cordova build android --release --buildConfig=..\myBuildConfig.json
Testing the App
- Using Cordova’s emulator
Now we can run our app. If you are using the default emulator you should use:
cordova emulate android
If you want to use the external emulator or real device you should use
cordova run android
