Answer 1

Use the following steps to generate android signed apk.

1. Generate a release build using following command,
   ionic cordova build android --release --prod

2. Go to the apk path using,
   cd platforms/android/build/outputs/apk

3. Generate private key using following keytool command,
   keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
   (Replace my-release-key with your app name and alias_name with key name (eg myappkey))

4. Sign the unsigned APK, by running the jarsigner.
   jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore android-release-unsigned.apk alias_name
   (Replace my-release-key with your app name and alias_name with key name (eg myappkey))

5. Copy zipalign tool from /path/to/Android/sdk/build-tools/VERSION/zipalign to platforms/android/build/outputs/apk .

6. Run zip align tool to optimize the APK.
   zipalign -v 4 android-release-unsigned.apk app_name.apk
   (Replace app_name with your app name)

   This will generate signed apk.

Firstly you need to move to the project's root directory and then:

You can generate debug (or testing) android-debug.apk using below CLI

ionic cordova build android --prod

This is needed for app store release mode build

ionic cordova build android --prod --release
