Ionic Android Signature Package configuration

Onic Android Signature Package configuration Android SDK tools configuration

The so-called Anrdoid package is to package the Ionic project into an apk file that can be installed on an Android system, when packaged, using the Cordova tool, but before you do, you need some preparation: Configuring the JDK, Android The SDK also has each Android version of the package download, the most important is the need to successfully create a ionic project, for the Ionic project to create a detailed tutorial, please refer to the following articles:

Configuring the JDK

The main process is the following: Download configure environment Variables test

Ionic Installation

Using the node and NPM settings, let's install the ionic and Cordova CLI.

$ npm install-g Ionic Cordova

Note: this-G means that this is a global installation, so you need to open the Administrator command Prompt for window. For Mac/linux, you need to run sudo with a command.

When you are done, create your first Ionic application:

$ Ionic Start HelloWorld blank

To run your application, please CD into the created directory and run the Ionic serve command to test your application in the browser!

$ CD HelloWorld

$ ionic Serve

Ionic packaged Android SDK

Production Build

To run or build your app for production, run

Ionic Cordova run Android--prod--release

# or

Ionic Cordova Build Android--prod--release

This narrows your application's code to ionic's source code and removes any debugging functionality from the APK. This feature is typically used when deploying applications to the Google Play store.

Sign Android APK

If you want to publish your app in the Google Play store, you must sign the APK file. To do this, you must create a new certificate/KeyStore.

Let's use the Keytool command that came with the JDK to generate your private key:

Keytool-genkey-v-keystoremy-release-key.jks-keyalg rsa-keysize 2048-validity 10000-alias My-alias

You will first be prompted to create a password for the keystore. Then, to answer other good tool questions, when all the work is done, you should create a file named My-release-key.jks in the current directory.

Note: Make sure to keep this file in a safe place, and if you lose it, you will not be able to submit the update to your application!

To sign an unsigned apk, run the Jarsigner tool, also included in the JDK:

Jarsigner-verbose-sigalg Sha1withrsa-digestalg Sha1-keystore My-release-key.jks Android-release-unsigned.apkmy-alias

This is the appropriate location for the APK. Finally, we need to run the zip alignment tool to optimize the APK. The Zipalign tool can be found in the/path/to/android/sdk/build-tools/version/zipalign. For example, on OS X with Android Studio installed, Zipalign is located in ~/library/android/sdk/build-tools/version/zipalign:

Zipalign-v 4 android-release-unsigned.apkhelloworld.apk

Verify that your apk is signed to run Apksigner. Apksigner can also be found in the same path as the Zipalign tool:

Apksigner Verify helloworld.apk

Now that we have our final version of binary file helloworld.apk, we can post this binary file on the Google Play store for the world to enjoy!
